Mate, your routine is unbalanced. Where is the leg work? Where is the back work? What equipment do you have access to? You would see much more benefits from full body 3 x week training. Throw in arm work once per week if you need to, but they will get hit with the bigger compound lifts. You are heading for muscular imbalance the way you are training, & injury down the track as a result.
You would benefit from doing compound exercises like squats, military press, rows, dips, pull ups, deadlift, bench.
