ULTIMATE WORK OUTS FOR YOUR BUTT
Barbell/dumbbell exercises – These are what you need to do with heavy weight if you want to make your butt BIGGER. Everything else will help make your butt rounder and firmer, but will not add significant size.
Cardio/plyometrics – This stuff is great for shaping your butt while challenging your heart at the same time.
Bodyweight exercises – I do these when I don’t have access to a gym. You can make these more challenging by holding heavy stuff like gallon jugs full of water.
