Pushups are great for working the upper body and chest, but they're also a great core exercise. You can add even more intensity by adding a jumping jack to your pushup. This is an advanced exercise, so modify by bending your knees or jumping the feet out and in without the pushup. If you have any back problems, you may want to avoid this exercise.
- Begin in a plank position with the hands wider than shoulders and the body in a straight line from head to heels.
- Jump the feet wide at the same time you bend the elbows into a pushup, going as low as you can.
- In a smooth movement, spring back up, jumping your feet back together into your plank.
- Continue with pushup jacks for 30-60 seconds.
