Set a barbell on blocks or raised platforms so it starts around knee height. Stand with feet hip-width apart and grip the bar. Brace your core and lift the bar by extending your hips and knees, keeping the bar close to your body and your back neutral. Stand fully upright at the top, then lower the bar back to the blocks in a controlled manner.
Log your barbell deadlift from blocks sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
