Best Chest Workout in Brief

The best gym chest workout starts with a heavy horizontal barbell press (3–4 sets of 6–8 reps), followed by an incline dumbbell press for the upper clavicular head (3 sets of 8–10 reps), chest dips for lower pec density (3 sets of 8–12 reps), and finishes with cable crossovers or pec deck flies (3 sets of 12–15 reps) for continuous mechanical tension.
