17. Step Jack to Star Jumps
Step jacks make an excellent way to warm up before you get down to the nitty-gritty of your exercise routine. They’re easy to do, and you can increase the difficulty to help you burn even more calories. These warm-ups are ideal for your glutes, calves, and inner thighs. Stand with your feet together and your hands at your sides, your palms facing forward. Raise both arms, keep them straight, and lift your right leg. Return to starting position, and then repeat with your left leg. If you want to increase the difficulty, jump with arms and legs spread wide like a jumping jack, but return them together before you land.
