A strong chest won't look that impressive if you don't have a well-developed backside to balance it out. Complete all sets of these back-building compound movements, and you'll soon see added strength to your lifts. As a bonus, you'll hit up your biceps and abs at the end of the workout.
Make sure you pick a challenging enough weight that the last 1-2 reps of each set are a challenge. Give yourself enough rest time between each set to feel recovered, but you shouldn't be taking more than 2-3 minutes.
