Huff Post speaks to Kaitlyn Colgan, PT, DPT, SCS, physical therapist at HSS on what not to do while exercising.

Warming up is a necessary first step for any workout, but Colgan said there’s one kind of warmup she avoids: static stretching.

“I think people often are like, I want to stretch before I work out, but just doing static stretching where you’re leaning into a stretch and holding for 30 seconds to a minute, that’s not necessarily going to be your best way to warm up,” Colgan said.

Instead, Colgan said a dynamic warmup or dynamic stretching is best before you jump into exercise. This can include body weight exercises like planks and push-ups or dynamic stretches like high knees or butt kicks.

"The biggest thing during a workout that I try to be cognizant of is not doing the same thing every single time,” explained Colgan. 

While working out in any capacity is good, it’s best for your body to have a mix of strength training and aerobic exercise to reap the full benefits.

“Getting a variation of those will give you more of the full scope of benefits of generalized exercise for the body,” Colgan said.

Plus, it’s safer to mix up your workout, too. “Doing the same thing over and over can lead to overtraining, which can cause injury down the line,” Colgan explained.
