A wide back is key to an aesthetically pleasing physique. With today's mix of exercises, you'll hit everything from your lats and middle back to your biceps and traps.
Visualize each movement to help target the muscle. If you're blasting your lats with the bent-over barbell row, remember to squeeze as hard as you can in the top, contracted position, and hold for a brief pause.
Challenge your body with each rep. You should be lifting progressively heavier whenever possible, so do your best to earn today's three-minute rest periods.
