A New Year means more people come to the party and with them they carry on believing in old views about fitness and weight loss. Science gets ignored and myths prevail. Good results sometimes require debunking bad ideas. Far too many enter the New Year with old ideas. They still believe fitness myths that were probably debunked years ago. The following are 10 myths that live on because their friends, coworkers, family members, and popular media continue to endorse them.
- Lifting weights makes you bulky. To be fair, my industry has come a long way in dispelling this one. But you’ll still get people, particularly women, who believe three-pound weights will build a lean, toned physique while anything heavier will likely lead to tighter pants. There are literally mountains of science-backed benefits linked to resistance training, like improvements in strength, mood, anti-aging effects and metabolism. Look it up. I’m not lying.
- The key to results: Eat a lot less and exercise a lot more. This one is so widespread. It’s convincing because it’s only partly true. You do need to be mindful of what you’re eating and for many that simply means eating a lot less. And most likely you need to exercise more frequently. The trick is not to tackle both at the same time, especially not at full speed.
- Keto is the best diet for weight loss. Another year, another diet. Just in the low-carb category, we’ve gone from Atkins to South Beach to Paleo and now to Keto. We could create separate timelines for everything from low-fat to vegetarian to fasts and cleanses. Do you see the ridiculousness? With each new fad, we learn yet again that no single diet is right for everyone, while some aren’t a good idea for anyone. When it comes to a lot of these popular diets, most people don’t completely understand the challenges of a particular diet. Stop following blind faith and believe in good ol hard work!
- A good workout burns a ton of calories. As someone in my industry who I admire, Gray Cook says, “First move well, then move often.” Burning calories is a byproduct of your physical activity. It will happen. But labeling any workout good or bad by the number of calories burned and you’re not getting the idea. You generally don’t burn a ton of calories in a workout. In fact, unless you are monitored with gas exchange equipment, it’s a best guess.
- Cardio is the only way to lose weight. Visit any gym on any day in January and you’ll be hard-pressed to find an open treadmill, elliptical, stationary bike, or stairclimber. It’s a sure sign that the general public still believes cardiovascular exercise is the premier way to drop pounds. After all, a cardio machine keeps a running count of the calories you’ve burned, like exercise is a video game and the goal is to get the highest score. Of course cardio exercise can burn a lot of calories. But there’s a catch: You have to do a lot of it.
- Stretching will loosen tight muscles. Humans evolved to move, not spend long hours sitting. We sit at our desks at work, on our couches at home, and in cars. The problem with traditional stretching is that it only pulls on a given muscle, with no consideration for the mobility or stability of the joints surrounding it. A more practical approach: improve range of motion and joint function.
- Big muscles are built with big weights. Bigger muscles are typically stronger, and stronger muscles are typically bigger. But the science of muscular hypertrophy is actually more nuanced. Load is just one of the major drivers of hypertrophy. You also need time under tension, which is achieved with moderate to high rep ranges and controlled movements, and volume. The more total sets and reps, the greater the training effect.
- Every workout needs to be all-out. Never judge the quality of a workout by how fast your heart is racing or how much you are sweating. What’s even more dangerous is going full throttle when you struggle with less than 50%. Learn to progressively increase workout loads and how beneficial it is to cycle your workouts.
- Deadlifting hurts your back, and squatting is bad for your knees. The only people who believe this are those who have never done either exercise properly. The squat and hip hinge movement patterns are vital for health and performance. The best training programs include multiple examples of both. You will receive greater benefit from either or both exercises, than skipping them altogether.
- Hiring a personal trainer will fix everything. For so many, contracting a personal trainer is a get-out-of-jail-free card. It means you can cheat on your diets, skip workouts, do whatever you want, etc. After all, you hired a trainer, and that should be enough, right? Don’t you wish. Having an experienced trainer, not some glorified cheerleader, for you will be the one stop solution to getting everything and more out of your fitness journey.
Til next time, train smart, eat well, and be better.
