I’m still undecided on whether or not we need personal trainers, at all. For centuries humans managed to exercise without someone telling them when and how to. That being said, we also didn’t used to sit around as much as we do, or consume so much processed foods. There was a time when our great, great, great ancestors got their exercise by literally hunting their food and scaling boulders. So, I do understand that, our regular activities don’t encourage us to use all of our muscles the way we once did. I also understand that maybe we don’t know how to safely use them all. So, do we need personal trainers at all? The jury is still out. But are there trainers who definitely do know what they’re doing and some that…don’t? Absolutely. Here is some bad advice personal trainers give women.
Do crunches for abs
The reality is that you can do crunches all day and you will not see abs if your body fat is too high. Abs hide under stomach fat, and we mostly lose stomach fat through diet (cardio plays a small role, too). Doing hundreds of crunches a day, without adjusting diet, will just lead to back pain and no ab definition.
