6. Glute Bridge
This can be done with your back on the ground and your hips lifted up. Drive your hips up with your feet firmly planted on the ground and squeeze your booty at the very top of the motion. To make this harder, you can rest a dumbbell on your pelvis, try pulses and holds, or add a resistance band. Doing glute bridges for just 40 seconds a day can help strengthen your bum, pelvic floor, and entire back body. Plus, it opens up the back and neck.
