CrossFit will help you build lean muscle while shedding your bodyfat. The use of fully functional movements mixed with high intensities will burn more calories and speed up your metabolism. Workouts are 60 minutes in length and your heart rate is elevated through different intervals throughout the whole class from warmup to cooldown. Dynamic warmups, strength and skill work, WOD (workout of the day), and a cooldown with stretching. This high intensity style training has been shown to burn up to an average of 20.5 calories per minute for males and 12.3 calories per minute for females.
