A hyperextension or back extension done on the plyo box is a great way to work your lower as well as mid to upper back muscles.
A plyo box is typically used in Plyometrics-style workouts, also called plyos or jump training. However, you can use the plyo box with other bodyweight exercises to add another level of challenge to your workout routine.
Lay on the box with the hips on the corner and hold on to the back or sides. Squeeze the glutes and hamstrings to raise the feet up to hip height ad then lower back down.
