Explosive Jacks Exercise

These power-boosting explosive jacks will increase your heart rate, improve your strength and help you burn more calories. But be warned -- this is hard work!

How to do Explosive Jacks:

• Stand tall with feet shoulder-width apart and your arms at your sides.
• Hop into a squat for two counts, bringing your knees together, bent over ankles.
• Cross forearms in front of chest, hands in fists facing the body. Keep back straight and lean slightly forward.
• From the squat, hope your legs out slightly wider than shoulder-width and hold for two counts.
• At the same time, open your arms out to the sides with elbows slightly bent and fists at shoulder height.
• Jump back into squat.
• Work up to two sets of eight jacks.
