To perform a one-leg glute bridge, start by lying on your back with one knee bent and the other leg extended straight in the air. Lift your hips off the ground by pressing through the heel of the bent leg, engaging your glutes and core, while keeping the extended leg elevated throughout the movement. Lower your hips back down to the ground and repeat for the desired number of repetitions to strengthen the glutes, improve balance, and address any muscle imbalances between the two legs.
