Stand about one leg-length away from a wall and place one foot on it at around hip height.
Slowly bend your knee to let your body drop forward.
Pause and then press through the ball of your foot to smoothly return to the starting position.
Keep your torso upright and neutral throughout the whole exercise.
Pushing on a wall instead of an elevated surface (like in the Incline lunge ) makes this exercise a bit easier from a strength perspective, but harder from a flexibility perspective.
