If you need a little extra motivation today, grab a buddy! Having a friend at the gym who can help push you will make a big difference in your workouts. You can also look at your "before" photos. By now, you should be seeing some excellent size development in every muscle group!
Once you're motivated, head to the gym armed with this hypertrophy-focused chest and triceps workout. It should be a fairly quick workout, but that doesn't mean you should rush your reps or sacrifice clean form. Make every rep count!
