This is a whole body exercise, it targets your Triceps, Glutes, Legs and Abs all at once.
In the beginning position, make sure your hips are off the floor. And your straight leg is tight.
It is very important to keep a good form.
This is one rep. Do 3 sets of 10 on each side. As you become more advanced, you can pause at the top of the Triceps Bridge for 10 seconds.
When you keep a perfect form in every exercise, you will engage a lot more muscles, and get a much better workout in a shorter time.
