You need cardio for fitness, health, and fat loss, but traditional cardio like running isn't the most effective option, and it's stressful on your joints.
The cure: a circuit-training routine that builds strength and endurance in one workout. Skip rope for 3 min changing your intensity levels through out then move directly to each one of the following exercises for 60 seconds— do as many reps as you can. Then rest 30 seconds and move on to the next exercise.
Complete the circuit twice, performing squats, pushups, paratrooper lunges, dips, and burpees with a jump. (Start standing up and then bend and put your hands on the ground and kick your legs back so that you end in the plank position. Then thrust your legs forward between your arms, and jump into the air.)...perform this workout on non weight training days and watch as your body scorches fat & builds lean muscle tissue.
