If you want to give your body weight interval routines some kick, try adding the following three body weight exercises to your routine. Of course, it is a matter of building up your strength to perform these exercises. You may not even be able to perform one rep but the more you practice, the stronger and better you will become.
One Armed Push-Up
The one armed push-up is a great body weight exercise to perform if you want to really build up your pectoral muscles. It is also good for your triceps and shoulders. Those two muscles are sure to feel the burn. The exercise is performed by placing one arm behind the back and lowering your chest to the ground using your other arm. If you really want a challenge, you can perform this exercise using a medicine ball, kettlebell, or with one leg raised.
One Legged Squat
I have tried the one legged squat and have yet to master one repetition. It is considered one of the best body weight leg exercises around. It is performed by extending one leg out in front of you with your arms up and straight ahead. You slowly lower yourself using the other leg until you hit the parallel bottom position, then slowly raise yourself back up. For added resistance you can also hold a kettlebell or dumbbell.
The Burpee
Performing these always tires me out. It is a great overall body exercise and works well for developing your core muscles. It is a little difficult to put into words how to perform this exercise, so check out the video:
