Sit with your upper back against a bench under a Smith machine bar and feet flat on the floor. Position the bar across your hips, brace your core, then drive through your heels to lift your hips upward until your body forms a straight line from shoulders to knees. Squeeze your glutes at the top and lower back down with control.
Log your smith hip thrust sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
