Performing a deadlift from a block decreases the range of motion, making the move slightly easier. Try this before progressing to deadlifts from the floor.
Grip the bar with your hands just wider than your feet, sitting in a hinge position with your bum back and your back flat. Lift the bar by pulling your hips through and standing up straight. Squeeze your glutes at the top, roll your shoulders back, and lift your chest up.
Then lower the bar back down to the block by sending your bum back in a hinge. You may need to bend your knees depending on how low the block is.
This exercise works your lower body and practices the hinge movement pattern.
