I’m an ast. manager at Gold’s Gym. I work and workout with trainers all day and they all say that jumping rope is one of the best cardio excersises a person can do. I’ve been using it in my workout regimen going on three years now and let me tell you, there is nothing better. I’m 6’0 and weigh between 175-180. If I didn’t include my jumprope routine it’d probably be a bit higher. It works that well. I do very little lifting. My workout is simple; my jumprope routine, 3-5 sets of 12 pullups, and running/walking for about 45 minutes to an hour. So if your not into weight training, this is the perfect calorie burning workout that also gives you shredded lean muscle. Here’s my 15 minute jumprope routine.
