Stand with feet wider than shoulder-width and toes slightly turned out, barbell elevated on stable blocks. Bend at hips and knees to grip the bar with hands inside your legs. Brace your core and keep a neutral spine. Push through your heels and extend hips and knees to lift the bar up, keeping it close to your body. Pause at the top, then lower the bar back down with control to the blocks. Repeat for reps.
