7 Glute Bridges That'll Wake Up Your Butt and Core

To add an extra effort to a single-leg bridge, add an abduction to the top. This will recruit your side glutes on top of your other muscles — and you'll likely feel it the next day.

• Lie on your back with your knees bent and feet flat on the floor, palms pressed into the floor by your sides. Find a slight posterior pelvic tilt, and then extend your right leg and lift it a few inches off the floor. This is the starting position.
• Press your left heel into the floor to lift your pelvis up until your body forms a straight line from shoulders to knees, bringing your right leg with you.
• At the top of the movement, pause and move your right heel out a couple of inches, then bring it back in.
• Slowly lower your hips to tap the floor. That's one rep.
• Do three sets of 10-12 reps. Repeat on the opposite side.
