Stand beside a wall and extend one arm up and slightly forward, placing your palm or forearm against the surface. Gently lean your body away from the wall to feel a focused stretch down the side of your torso and into your lat muscle. Keep your hips square and breathe steadily to enhance flexibility and reduce tightness.
Log your single arm lat stretch against wall sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
