Heel Lift Squat
With your feet about the width of your hips apart, lift your left heel clear of the floor. Now lower your bum by pushing back with your hips, raising your arms in the air at the same time. When your thighs are roughly parallel to the floor, return to the starting position. After 10 reps with your left heel raised, do the same with your right heel off the floor. Works quads and glutes.
Single Leg Glute Bridge
Lie on the floor with bent knees, as if you were going to perform sit ups. Extend your left leg and lift your butt off the floor by squeezing your glutes and raising your hips, before lowering it back to the floor again. Aim for 15 repetitions on each leg. This exercise will give your core a work out as well as your glutes.
