There are very few aspects of fitness that can’t be developed using just your own bodyweight. Upper body explosive strength is certainly not one of them, and the GOFLO Trainer is a great tool that can help to train it.
The GOFLO clapping push-up requires that you forcefully "jump" your hands to a height at which you can clap and then quickly return your hands to the floor. The clapping pushup requires strength and speed. You will strengthen the muscles of your upper body, including your chest, arms, shoulders and core.
