Jumping jacks and jumping rope are exercises you can incorporate into aerobic or anaerobic workouts. These activities are ideal for warming up your muscles before engaging in more vigorous physical exercise such as sprinting, swimming, weightlifting or sports. They also are good complementary exercises you can integrate into circuit training workouts. Doing jumping jacks or jumping rope between anaerobic exercises helps to keep your heart rate elevated, which optimizes the circuit training objectives to increase muscle strength and develop cardiovascular endurance. The two exercises are ideal in that they do not require a lot of space to perform or large equipment such as a treadmill or elliptical trainer.
