The dumbbell single-leg hip thrust is a single-sided exercise that targets the posterior chain, particularly the glutes and hamstrings. It involves balancing on one foot and fully extending your hips while holding a dumbbell across the front of your hip. It is a great movement to activate the glutes prior to other lower-body training, but can also be performed in the main part of a workout, or for high reps as a glute burnout.
