Great Stuff!
You can also include push-ups, there a several you can do, from regular push-ups to hands close together pushup--works more of the triceps--to off set push-ups, where one hand is on something (like a small medicine ball) and one is not--and also band push-ups.
All of these variations will hit the muscles a bit differently--and they will all give you a fantastic upper-body workout.
Yes, you are very right. Push ups are great for the upper body! Thankyou for sharing all this information :)
