The single-leg deadlift is a strength training exercise that targets the muscles in the legs, glutes, and core. It involves balancing on one leg while lowering a weight, such as a dumbbell or kettlebell, towards the ground. This movement helps improve stability, balance, and coordination. To perform the exercise, stand on one leg with a slight bend in the knee. Hinge at the hips, extending the other leg straight behind you while lowering the weight. Keep your back straight and core engaged. Return to the starting position by driving through the heel of the standing leg.
