This is an interval session that involves 2-3 minutes of jumping rope and running. A rest period follows each interval combo (jump/run). If you don’t have a jump rope simply jump in place as though you were actually jumping rope. Ok? The workout begins with a short series of dynamic warm-up exercises. At the end of this program you’re asked to do a one-minute plank. Jefit Strong, Michael Wood, CSCS JeFit Team Member
