All you need is a chair or bench and something solid to grab onto.

This is a Single Leg Bench/Chair Squat.

On the page, I'll give you the full rundown on how to set it up and how to get the most out of it, including how to add resistance when bodyweight gets too easy.

If you really want to build up your glutes fast, use this exercise in conjunction with my Daily Specialization program, found here.

It only takes a few minutes a day and it'll build up your glutes faster than anything else I've tested.
