Set-up: Set up with barbell resting on your upper back and traps. Lift the off leg slightly off the ground and slightly bend that knee.
Movement: Initiate the movement by hinging at the hips and lowering your trunk forward as your off leg moves backward. Lean forward until your trunk is nearly parallel with the ground, and return to the start of the movement focusing on firing your hamstrings and glutes. Brace through your core and keep a neutral spine throughout the movement. Do not lower your trunk past a place where you can no longer maintain that neutral spine position. Focus on form first and range of motion later.
Repetitions: Perform all prescribed reps on one side, then on the other. This counts as one set.
