Don't Do That!

We should stretch before we get active – right? No!

You can skip those big stretches before you work out. According to personal trainer Dmitriy Petrov, touching your toes or bending side to side can do more harm than good. The whole purpose of a warm-up is to heat up your muscles so they’ll be less prone to injury. Dramatic stretches like that don’t raise your body temperature and are just stressing out your cold muscles.

The best warm-up techniques include dynamic stretches like jumping jacks, peddling or even a slow walk for a few minutes.
