Fix It with Partial Reps…
Set up a box about 2 inches behind your body. As you squat back, sit on the box so your upper thighs are parallel to the floor. Then stand back up. Complete 1 to 3 sets of only 1 to 3 reps each. As you become stronger, use higher boxes and add weight, which creates more tension.
Why it works: The box removes all momentum where the lift is most challenging, which forces your muscles to work harder to start back up. And by limiting your range of motion, you learn to handle heavier loads.
