WIDE GLUTE BRIDGE
Start by lying on your back with bent knees and feet flat on the floor, wider than your hips (a). Make sure your toes are turned out in line with your knees. Press through your heels and engage your glutes to lift your hips up (b). You should aim to have your hips, knees, and shoulders in a straight line. Don’t forget to keep your abs engaged and your glutes squeezing to prevent your lower back from dropping. Do 20 repetitions.
