Last week I had a conversation with someone who had never tried CrossFit but had always wanted to. After chatting for a few minutes I knew that CrossFit could be a great fit for this woman and her physical and athletic goals. I also knew that the gym environment (Roots) would be a welcoming place for someone who had been “beat down” by fitness programs over the past 15 years.
Then came her concern, “I’ve just never wanted to do CrossFit because, you know, lifting heavy weights has always made me bulk up.“
As a new-to-CrossFit female back in 2007, I was drawn to CrossFit and the chiseled and lean physiques of the women who dedicated their time to the program. They had abs, they were strong, and they looked like athletes.
But in the back of my head I did wonder, would I get bigger doing this program? Sure I want muscles but I don’t want muscles that are too big.
Luckily, I came across this article,
It’s helpful. Read it. If you’re a man and you also fear
After 11 years of doing CrossFit, I can attest to everything outlined in this article – both as a CrossFitter for the past 12 years and as a CrossFit coach for the last 11 years. Getting bigger is a goal, a dedicated choice, and largely enabled by the food you consume in concert with the training program you select.
Top 10 Reasons Heavy Weights Don’t Bulk Up the Female Athlete
1. Women do not have nearly as much testosterone as men.
In fact, according to Bill Kreamer in Essentials of Strength Training and Conditioning, women have about 15 to 20 times less testosterone than men. Testosterone is the reason men are men and women are women. After men hit puberty, they grow facial hair, their voice deepens, and they develop muscle mass. Because men have more testosterone, they are much more equipped to gain muscle. Because women do not have very much testosterone in their bodies, they will never be able to get as big as men.
2. The perception that women will bulk up when they begin a strength training program comes from the chemically-altered women on the covers of bodybuilding magazines.
These “grocery stand models” are most likely pumped full of some extra juice. This is why they look like men. If you take the missing link that separates men from women and add it back in, what do you have? A man!
For women, toning is what happens when the muscle is developed through training. This is essentially bodybuilding without testosterone. Since the testosterone is not present in sufficient amounts, the muscle will develop, but it won’t gain a large amount of mass. The “toned” appearance comes from removing the fat that is covering a well-developed muscle.
3. Muscle bulk comes from a high volume of work.
The repetition range that most women would prefer to do (8–20 reps) promotes hypertrophy (muscle growth). For example, a bodybuilding program will have three exercises per body part. For the chest, they will do flat bench for three sets of 12, incline for three sets of 12, and decline bench for three sets of 12. This adds up to 108 total repetitions. A program geared towards strength will have one exercise for the chest—flat bench for six sets of three with progressively heavier weight. This equals 18 total repetitions. High volume (108 reps) causes considerable muscle damage, which in turn, results in hypertrophy. The considerably lower volume (18 reps) will build more strength and cause minimal bulking.
4. Heavy weights will promote strength not size.
This has been proven time and time again. When lifting weights over 85 percent, the primary stress imposed upon the body is placed on the nervous system, not on the muscles. Therefore, strength will improve by a neurological effect while not increasing the size of the muscles.
5. And, according to Zatsiorsky and Kreamer in Science and Practice of Strength Training, women need to train with heavy weights not only to strengthen the muscles but also to cause positive adaptations in the bones and connective tissues.
6. Bulking up is not an overnight process.
Many women think they will start lifting
7. What the personal trainer is prescribing is not working.
Many female athletes come into a new program and say they want to do
8. Bulking up is calorie dependant.
This means if you eat more than you are burning, you will gain weight. If you eat less than you are burning, you will lose weight. Unfortunately, most female athletes perceive any weight gain as “bulking up” and do not give attention to the fact that they are simply getting fatter. As Todd Hamer, a strength and conditioning coach at George Mason University said, “Squats don’t bulk you up. It’s the ten beers a night that bulk you up.” This cannot be emphasized enough.
If you’re a female athlete and training with heavy weights (or not), you need to watch what you eat. Let’s be real—the main concern that female athletes have when coming to their coach about gaining weight is not their performance but aesthetics. If you choose to ignore this fact as a coach, you will lose your athletes!
9. The freshman 15 is not caused by strength training. It is physiologically impossible to gain 15 lbs of muscle in only a few weeks unless you are on performance-enhancing drugs.
10. Most of the so-called experts are only experts on how to sound like they know what they are talking about.
The people who “educate” female athletes on training and nutrition have no idea what they’re talking about. Let’s face it—how many people do you know who claim to “know a thing or two about lifting and nutrition?” Now, how many people do you know who actually know what they’re talking about, have lived the life, dieted down to make a weight class requirement, or got on stage at single digit body fat? Invariably, these so-called experts are also the people who blame their gut on poor genetics.
These so-called experts are the reason you see so many women doing sets of 10 with a weight they could do 20 or 30 times. They are being told by the experts that this is what it takes to “tone” the muscles. Instead, they are only wasting their time doing an exercise with a weight that is making no contribution to the fitness levels or the development of the muscle.
In case you haven’t figured it out by this point in the article, what is currently being done in fitness clubs to help female athletes tone their bodies is not working. It’s not helping these women get toned, and it is definitely not helping improve athletic performance. Maybe it’s time for a change. Contrary to the ineffective light weights currently being used, heavy weights offer many benefits for women including improved body composition, stronger muscles, decreased injury rate, and stronger bones (which helps prevent osteoporosis). Let’s try lifting some heavy weights and controlling our diet and watch this logical, science-based solution make the difference we’ve been looking for.
