Optimize Your Workout: Train Back and Biceps Separately

Lat Pulldown Variations You Shouldn’t Skip Both overhand and underhand lat pulldowns train your back, but they place slightly different emphasis on the muscles involved. 👉 Overhand grip: Builds back width and overall lat development. 👉 Underhand grip: Increases biceps involvement while still targeting the lats. Don’t overthink it. Alternate them or program both and your back will grow stronger, wider, and more balanced. 💪 #synermuscle #latpulldown #backtraining #lats #pullworkout
