If you think bodyweight workouts aren't difficult enough, a booty band really ups the intensity. This ladder from personal trainer Bret Contreras, PhD, who calls himself the "Glute Guy" on Instagram, shows a booty workout that only uses two moves — glute bridges and supine hip abductions — and a booty band.
To really feel the burn, Bret recommends performing them as a ladder, starting with 13 (or 15 if you're really advanced): 13 bridges and 13 abductions, then 12 bridges and 12 abductions, all the way down until you get to one. This will really burn out your glutes, so feel free to take rest breaks in between if you need to!
