Thoughts on movement, fitness, training and gym culture.

Iron is a Girl's Best Friend! Again!

October 22, 2016 Jennifer Thomson

Today I'm reposting one of favourite pieces! I really enjoyed writing this one, as I was able to incorporate my own knowledge, experience and love for lifting into an article that I think is pretty interesting and enlightening to read! I'm also reposting this one because I have BIG NEWS: Small But Mighty will now be offering Semi-Private Women's Basic Barbell and Powerlifting in the Queen West area beginning Saturday November 5th! Check out all the details on the 'MIGHT IS RIGHT' program and grab your spot here!

Batman is one of my favourite superheroes, not only because of his dark and stormy mystique but also because he is just a 'regular guy,' with no innate superpowers like x-Ray vision or superhuman strength. He relies on both his mental strength and physical will to defeat his enemies, and often undergoes quite a beating doing so. Every time I lift heavy, I'm reminded of a quote from the Dark Knight, when Batman and the Joker come face to face in the 'final showdown' for Gotham City: "...This is what happens when an unstoppable force meets an immovable object..." It took me a few years of lifting to realize (and gain the confidence to be sure) that I am that unstoppable force, and though lifting is always a physical and mental challenge, the barbell is certainly not immovable. 

I think that the first paragraph of this post highlights one of the main reasons why I love lifting myself and programming it for my clients: confidence and empowerment! There have been too many times to count when faced with a mental or physical challenge I've thought to myself, "if I can squat 200 lbs, I can certainly do this"... And I'm not the only one! I've had clients report similar experiences in their daily lives, in situations ranging from moving furniture to surviving pregnancy, labour and delivery! With every kilo lifted, there comes a sense of accomplishment, of having done some 'work', of having put in time and effort towards a bigger goal or purpose! While you may leave a lifting session both mentally and physically exhausted, it is there, that little spark that keeps you coming back to the bar for more. 

In addition to building strength, a periodized resistance training program will also positively impact your body composition; it will help preserve your lean muscle mass, and may also lead to an increase in your basal metabolic rate (i.e. the rate at which you burn calories while resting). For women specifically, regular weight-training will also positively impact your bone health, and help prevent osteoporosis; this is very important in times of peak bone growth, as well as in the elderly.

Also, a well-organized lifting program will decrease your risk of injury by improving your balance and coordination, and may also benefit your sport-specific performance (Healthline 2013). In fact, studies have shown that in as little as 8 weeks, a heavy squatting routine can improve running economy and time to exhaustion at maximal aerobic capacity in highly-trained male and female long-distance runners (Storen et al, 2008).

With regards to sports participation, a prospective study of over 1200 high school athletes demonstrated that untrained female soccer, volleyball and basketball players had a 3.6 greater incidence of knee injuries versus female athletes that underwent a neuromuscular training program including weight-lifting, plyometric movements and flexibility training (Hewett, 1999). In the elderly, periodized resistance training has been shown to increase quality of life, improve power, body composition, and energy expenditure, and reduce the difficulty of completing acts of daily living (Hunter et al, 2004). 

Finally, on a personal note I have to say that through lifting I have met some of the most awesome and life-strong ladies I know! Girls that can lift heavy, run fast, eat burgers and rock a summer dress like the best of them! I mention this because there is an expectation that lifting will automatically make girls bulky! This is NOT true! While aesthetics is certainly the last reason I would promote as motivation to lift, resistance training is certainly figure-friendly. My female lifting pals and I get compliments on our figures all the time...funnily enough, the women providing the compliments often don't ask how I train, they only ask how-often. Its one of my favourite things to fill them in on my little iron secret! Seriously though, if you're all about that bass, squats are for you!

I also love lifting because its cathartic, quiet and focused. In the weight-room, there is no pressure to look pretty, to move in a 'lady-like' way, or even to play the most up-to-date music! There is just you, the bar, and if you're lucky, some other awesome ladies to cheer you on and spot you when you need it! In short, lifting is an awesome way to make new friends, build mental and physical strength, increase the resiliency of your muscles and joints, and improve your sport-specific performance. So head on over to your local gym, grab a rack and get lifting. If you're looking to get strong, your barbell will be your new best friend.

Training and the Delivery Room: Trese Z + Jenny T

July 19, 2015 Jennifer Thomson

Labor is a natural process that results in the birth of one or more infants; "normal" birth begins with the spontaneous onset of labour between 37 and 42 weeks gestation (1). Infants born prior to 37 weeks are considered premature, and those born after 42 weeks are considered postmature. 'Gestational age', a measure of fetal age/maturation, is measured in weeks from the first day of the woman's last menstrual cycle to the date of measurement (2). Although labor is a normal physiological process, it is associated with significant risks of maternal and fetal morbidities, and occurs in three stages (1):

  1. Commencement of regular painful contractions to full cervical dilatation
  2. Full cervical dilatation to birth of the infant
  3. The interval between delivery of the infant and delivery of the placenta and membranes

In the past, it was believed that exercise during pregnancy, particularly the third trimester increased risk of preterm delivery, however, recent research suggests this is not the case. In fact, a randomized controlled trial comparing 70 women engaging in supervised moderate intensity resistance exercise between 12 and 38 weeks of gestation to 70 inactive women suggested there was no difference in gestational age between women who engaged in training and those who did not (3). A study of 131 well-conditioned recreational athletes engaging in aerobic and endurance exercise during pregnancy offered similar results, suggesting women who exercised at or above 50% of their pre-conceptional level had a lower incidence of abdominal and vaginal operative delivery, as well as a shorter period of active labor, with similar rates of pre-term labor to the inactive group (4). Although birthweight tended to be lower in the exercising group, clinical evidence of fetal distress was less frequent in these women, suggesting a beneficial effect of aerobic activity on the course and outcome of labour (4). Exercise during pregnancy has also been associated with shorter hospital stays, fewer maternal and fetal complications, and decreased health-care costs (5).

There is certainly more to be said for the benefits of prenatal exercise on labor outside of demonstrating that it does not cause preterm labour. While research in the area of prenatal exercise and labor is variable, some sources suggest women who exercise while pregnant have lower rates of cesarean delivery as well as lower rates of perceived exertion during labor (5). Additionally, research completed at the Trondheim University Hospital and several outpatient Physiotherapy clinics in Norway suggests not only that pelvic floor training during pregnancy strengthens the pelvic floor muscles, it also prevents urinary incontinence in 1 out of 6 women during pregnancy and 1 in 8 women post-pregnancy (6). In addition, it also suggests that intensive training of the pelvic floor muscles during pregnancy facilitates labour and may also prevent a prolonged second stage of labor (active pushing) in as many as 1 in 8 women (6).

Finally, the impact of prenatal exercise on stress, mood and birth outcomes cannot be overlooked. Recent research suggests that stress and negative mood during pregnancy increases the risk for both postpartum mood issues, as well as poor childbirth outcomes such as earlier birth, younger gestation age and lower birthweight (7,8). A recent study of pregnancy-specific stress and birth outcomes linked high levels of pregnancy-specific stress to pre-term delivery as well as low birthweight. In this same study, prenatal exercise and healthy eating were inversely related to pregnancy-specific stress (8). 

While all of this information is promising, the main theme running through this series has been individuality. Each woman will both engage in and respond to exercise in her own way. Please note that all exercise performed in the aforementioned studies was supervised to ensure both appropriateness as well as safety for both mum and baby. Obstetrics Nurse Trese Zannis expands on this concept based on her experience in the Sunnybrook Labour and Delivery rooms: 

“My experience in the birthing unit at SHSC has allowed me to work with women of varying backgrounds, socioeconomic statuses, and ages; providing one-to-one care in such a setting allows for the formation of a bond between the patient and myself. I have had patients that range from athletes to the women who enjoy walking in their spare time. Even though each patient comes with their own exercise background, there has been one commonality between them all: physical activity in pregnancy (when done under the supervision of a doctor and interdisciplinary team) has many benefits. My experiences with exercise in pregnancy and how it can be beneficial in the labor and delivery period are all anecdotal…I once had a patient who was a competitive runner tell me that continuing to be active in her pregnancy allowed her to cope better with the labor experience and that she had an easier time healing in the postpartum period. I have also had women who continued to do such things as: yoga, walking, and weight lifting tell me that not only was the pregnancy more manageable (with regards to less fatigue and more energy), but that they felt more prepared for the labor and delivery process because they were used to pushing their bodies in some capacity when they exercised. So while exercise posits a plethora of benefits, one should always consult their physician and interdisciplinary team of health care providers before starting or continuing an exercise regime in pregnancy.”

My Training for Two Story: by Susan L

July 17, 2015 Jennifer Thomson

I’ve been active my entire life. I did gymnastics and rode horses as a small child, played soccer, volleyball and ran track as an adolescent and young adult, and started dancing competitively in my 30’s.

Right up until I got pregnant, I was dancing about 10 hours per week and running an/or lifting weights 1-2 times per week. I also played soccer on the weekends.

After doing a bit of internet research and speaking to my OB and nurse, I really had no concerns about training during pregnancy except for any activities that involved contact. The only thing I stopped doing was playing soccer to avoid the risk of getting hit.  I continued dancing and running hills, mowing lawns,  and playing occasional sports such as volleyball, tennis, I even did the Warrior Dash when I was 16 weeks pregnant.

Throughout my pregnancy, I felt that I knew my body well enough to adjust my activity level as I went along based on how I was feeling. My bottom line, if anything hurt or became abnormally uncomfortable, I wouldn’t do it. My cardio fitness went first, I felt short of breath often during aerobic exercise.

By the time I got to about 6 months pregnant, I could no longer run. It was too uncomfortable and sometimes painful with the pressure of my growing belly. I could still dance and lift weights and walk, so I did as much as I could comfortably do. I walked everyday and lifted light weights a few times per week.  I never worked with a fitness professional, I just did my own thing. My main goal was to keep my weight gain to the recommended amount and keep my energy and fitness level up. I continued doing all of these things right up until the birth of my son. In fact, during the final week of my pregnancy, I was trudging through the deep snow for 2 hours per day, trying to encourage labor to start.

I had a tough labor and delivery, I truly feel that if I was not in good physical shape, my birth story would have had a different ending. My fitness level and core strength were huge factors in the birth of my son. My physical fitness gave me confidence in myself and enabled me to keep a positive attitude throughout my long and challenging labor and birth.

I attribute the speed of my post partum recovery partially to the level of fitness I maintained throughout my pregnancy.  I used the same principals for going back to training. I listened to my body and only did what felt right. Being able to exercise again was a big relief for me. I followed the general rule which is to wait until your 6 week check-up at the doctor. All went well, and I was cleared to exercise again. I began walking daily 1 week post partum, started running and dancing 6 weeks post partum and doing CrossFit classes 12 weeks post partum. I was back to my pre-pregnancy weight/size after 5 months.

Most people around me were very encouraging and positive about my activity level. Sometimes I felt like I was not cautious enough because many of my friends felt that they were putting their babies at risk if they exercised. My husband was very encouraging as well,. He supported me throughout the entire process. One of my role models is my mom, she told me to do whatever I was doing before I was pregnant. She rode her horse when she was pregnant with her 3 daughters. She’s a free spirit, to say the least.

A few years ago, this picture almost broke the Internet! It sparked huge controversy as people from all over the world offered unsolicited opinions on whether a woman in her third trimester should be exercising in this manner or at this intensity. It seems at this time, on a general scale, people follow one of two trains of thought: either exercise is unsafe during pregnancy, or exercise is essential for a healthy pregnancy. So what does science say? The short of it is, the safety and benefits of exercise during pregnancy depend on the person.

Lets get the legal stuff out of the way first: this series is NOT a substitute for medical advice; it’s not a green light to go postal and lift cars on your way to work! While I recognize that most expectant mothers and moms have what can be described as 'superhuman capabilities', not ALL exercises are recommended during pregnancy, and not all women will have the same response to training. The best pre-natal training plan is one that is developed and monitored by an interdisciplinary team, with input not only from your physician, but also from your trainer, and most importantly, from yourself!

In 2003, both the American College of Obstetricians and Gynaecologists (ACOG) and the Society of Obstetricians and Gynecologists of Canada (SOGC) created guidelines regarding exercise during pregnancy and the postpartum period.  The major recommendation of each of these guidelines was this:

“All women without contraindications should be encouraged to participate in aerobic and strength-conditioning exercises as part of a healthy lifestyle during pregnancy(1,2).”

Participation in regular weight bearing exercise during pregnancy has been shown to have numerous positive effects including psychological benefits, improving maternal fitness, restricting weight gain without compromising fetal growth, and hastening postpartum recovery(3). Both the Canadian and American guidelines further suggest that not only may a woman continue to exercise during pregnancy, but she also may BEGIN to exercise during pregnancy, as long as she does so slowly and smartly(1,2). For the previously inactive woman, the 'best' time to begin an exercise program is in the second trimester, once the nausea, vomiting, and fatigue that characterize the first trimester of pregnancy have subsided(2). Aerobic exercise, (read: cardio), should be taken on gradually, beginning with 15 minute sessions of continuous exercise three times per week, slowly increasing to 30 minute sessions, 4 times per week (2). For elite athletes, the SOGC recommends a custom program, with supervision from an obstetric care provider who has an in-depth knowledge of the impact of strenuous exercise on both fetal and maternal outcomes(2). Although Alysia Montano, (pictured above) is unbelievably inspiring, her physical activity regimen will not be ideal for all pregnant women; in general, for previously active women, the SOGC recommends the following with regards to aerobic training during pregnancy:

“Reasonable goals of aerobic conditioning in pregnancy should be to maintain a good fitness level throughout pregnancy, without trying to reach peak fitness, or train for an athletic competition(2)”

Having said all of this, it is important that exercising pregnant women focus on balancing their training with proper nutrition, adequate hydration, and rest; they must also avoid large increases in their body temperature by exercising in loose clothing in a temperature controlled environment (3). Here are some other tips provided in these guidelines to help ensure safe and efficient pre-natal and postpartum training:

Women should choose activities that will minimize the risk of loss of balance and fetal trauma(2,3). As changes occur in weight and weight distribution, coordination and balance may be affected; exercise programs should be modified if they pose a significant risk of abdominal injury or fatigue, such as the removal contact sports, water skiing and scuba diving (3). Bicycle riding should be avoided after the first trimester as a result of changes in balance and risk of falling(3).

Exercising in the supine or prone positions should be avoided after the first trimester (1-3) as compression of the vena cava (a large vessel returning blood to the heart), may be caused by the pregnant uterus. Additionally, the ability to perform abdominal exercises may be impeded by the development of diastasis recti (separation or tearing of the rectus abdominal muscles at their midline junction) and associated abdominal muscle weakness(2).

Exercise intensity should not exceed pre-pregnancy levels(3). Because there are changes in circulation, and consequently heart rate and blood pressure in the pregnant population, exercise intensity should not be regulated by heart rate, but rather by how hard a woman believes she is working; generally, a 'moderate to hard' intensity is safe for women who are accustomed to this level of exercise (3). Tools that can be used to monitor exercise intensity in this manner include the 'talk test' and the Borg Scale for Rating of Perceived Exertion (2). 

Resistance exercise and flexibility training may also be included in the prenatal exercise prescription (1-3). There are certainly some precautions that must be observed here! With regards to resistance exercise, heavy weightlifting, powerlifting and other activities that require straining should be avoided(3). Neither the Valsalva maneuver nor breath holding should be used during pregnancy, nor should any other activities or techniques that result in the 'pressor response' (a quick and large increase in blood pressure) (1-4). General recommendations for resistance training during pregnancy include the following(4):

  • Avoid breath holding/Valsalva Manueuvers
  • Use weight machines or resistance bands rather than free weights to decrease the risk of injuries caused by changing centre of balance
  • Decrease resistance (weights), increase repetitions and use shorter sets
  • Focus on maintaining proper form during all lifts!
  • Avoid Powerlifting activities

With regards to flexibility training, both the woman and her trainer must be aware of the effects of Relaxin on ligaments and joint laxity. Flexibility training should be very slow and controlled, focusing on joint stability in new found positions (1-4). 

Initiation of pelvic floor exercises in the immediate postpartum period may reduce the risk of future urinary incontinence(2). Returning to exercise postpartum is an extremely individualized issue! There is no definitive period of time that a woman must wait before returning to exercise, however, the decision should be made in consultation with her medical team, considering issues such as the duration and intensity of labour, whether she underwent a cesarian delivery, her activity level pre-pregnancy and prenatally, and how she is recovering post-delivery (4). According to the American College of Obstetricians and Gynaecologists, exercise routines may be resumed gradually as soon as it is physically and medically safe (1). Many women begin to plan their return to exercise with their physician at their 6-week postpartum check-up.

For the breastfeeding new mother, moderate exercise during lactation does not affect the quantity or composition of breast milk, nor does it impact infant growth(2). Mothers who find that their baby does not feed as well immediately post-exercise may consider pumping breast milk pre-exercise, or waiting an hour post-exercise before feeding (2). 

Signs that you should stop exercising and seek medical attention include (1-4):

  • Vaginal bleeding
  • Dyspnoae (shortness of breath) before exertion
  • Cramping
  • Dizziness or Significant Nausea
  • Headache
  • Chest Pain
  • Muscle Weakness
  • Calf Pain or Swelling (need to rule out thrombophlebitis/blood clots)
  • Preterm Labour
  • Decreased Fetal Movement
  • Amniotic Fluid Leakage
  • Persistant Pain
  • Chronic Fatigue

Lastly, there are some very stringent....

GUIDELINES ON WHO SHOULD NOT EXERCISE (1,2):

&nbsp;

 

As you read through this article, I'm hoping you gleaned one very important thing: Training during the Pregnancy and Postpartum period, while generally safe, is extremely individualized and complex. Decisions on the frequency, type, intensity, and length of your training sessions should be based on your training history, prenatal health and made with input from a variety of WELL INFORMED sources including your physician, trainer, and yourself! Listening to your body is essential, as is open and honest communication with your healthcare team! Up next, read my close friend Zartaj's personal 'Training for Two' Story!
