“These are one of my favorites because they are great for both strength and cardio, and they can be done anywhere, on either a flat surface or with a step or bench,” Edwards says.
Start with your right food in front and your left leg behind you, with your knee bent just over the ground. Using power, jump in the air and switch your legs so that the left foot is in front and the right is in back. For a low-impact option, step the feet together to switch legs instead of jumping. Continue alternating legs for 30 seconds, completing as many repetitions as possible. Repeat three times.
