EQUIPMENT: BODYWEIGHT
VARIANT 01
Stand with your arms at your sides and your feet together. In one movement, jump up and spread your legs apart as you raise your arms to the sides and over your head. You should land with your arms over your head and your feet more than hip width apart. Immediately jump up again and in one movement, bring your legs together and your arms back to your sides. That completes one jumping jack. Continue in this manner. When doing jumping jacks in a HIIT cardio workout, work intervals can either be for time (ie, 30-60 seconds) or reps (ie, 20 reps, 50 reps). When using jumping jacks for cardioacceleration, do them for 30-60 seconds between lifting sets.
