Exercising is one of the best ways to stay healthy. But certain exercises should never be done even though they are popular. Read on to learn what these exercises are and some better alternatives you should be doing instead.
Crunches seem to be the go-to exercise to work out your ab muscles nowadays, but in reality they aren't much better for you than sit ups. Every time you do a crunch you are bending your spine and over time this can cause damage -- at best this can just cause bad posture, but even worse it can cause permanent injury. A much better and safer way to work out your ab muscles and your entire core is to do planks instead.
