This excuse is most often voiced by an athlete who already has a background in sports or exercising.
"They believe they have to spend hours at the gym, and that it isn't possible to get a full workout in such a short amount of time," says Coach Patrick.
What many former athletes don't realize—but quickly discover once they actually try CF—is that the amount of work you do in a typical one-hour class is equivalent to several hours in a regular gym.
You are constantly moving, and what's more, you are continually working several parts of your body at once.
Take the CrossFit staple exercise, the Burpee.
This movement alone not only works your cardiovascular system, but also your legs, core and arms.
Pair it with some Pull-Ups, Squats and Sit-Ups and you've got yourself a hell of a strength-building, calorie-incinerating training session.
