Squat Side Kicks: Stand with your feet parallel and shoulder width apart. Bend your knees and squat to a 90 degree angle, with your hands held out in front of you. Then stand back up and lift your right leg out to the side. Step your foot back to the shoulder width position and squat again. This time you will lift your left leg to the side.
Speed Bag Punches: Raise your arms slightly below chin level and make sure your elbows are parallel to the ground. Make a fist, and alternate punching motions. You can also adjust the speed.
Cross Jacks: This is like a typical jumping jack, but instead you will alternate crossing your left foot over your right foot each time you jump. You can also choose to alternate your arms as well.
Skaters: Start with a squat, then jump sideways to the left and land on your left leg. Then bring your right leg behind your left ankle without letting it touch the ground. You can count this as one rep, or repeat with the other leg and have that count as one.
