When you’re trying to advance your fitness yet don’t have the time to research everything you need to know to do it, you’re left to rely on advice from “the experts.” Of course, the hope is that these nuggets of wisdom will help you develop a more toned body, but sadly that isn’t always the case.Here are a few of the pieces of worst advice we’ve ever heard about fitness:“There’s only one way to get fit.” If someone tries to sell you on the idea that their program or routine is the only way you’ll ever get in shape, then realize that they’re not just concerned with improving your fitness. They’re probably more interested in selling you their products or services.“No pain, no gain.” While it’s normal to feel some discomfort when you’re building your muscles and challenging your body, the reality is that you shouldn’t be feeling pain. If you are, either you’re pushing yourself too hard or doing something wrong, neither of which is good.“Cardio is better” or “Resistance training is better.” Certainly, all fitness experts probably have their preference when it comes to cardio activity or resistance training, but you need both in order to have the best level of fitness possible. Cardio helps keep your weight down whereas strength training keeps you looking thin and trim, more toned.“If you’re thin, you’re healthy.” Being within your ideal weight range is good, but true health is more than that. You can be what is called skinny-fat, which means that your weight is okay but you have too much fat around your internal organs. Fitness means that you’re healthy inside and out.These are just a few pieces of bad advice we’ve heard about fitness. Any that we’ve missed? Feel free to add them below!
