You have four different exercises for each main muscle groups on each day. The only problem is that eventually your muscles will get used to the motions and you'll see less and less improvement, you'll stagnate in term of strength and muscle size.
What I suggest you do is choose 2 of the 4 exercises and do that for the week, the following week do 2 different exercises, this will help to stimulate your muscles more and keeps it stimulated longer. You may want to add some compound movements as they work multiple muscle groups which means more muscles are working together so more energy is expended. Compound exercises such as squats also helps to release more testosterone which helps to build muscle.
I'm aware that I've given you a lot of information in 2 posts. Try and add the information i've given you slowly over time so you can incorporate it into your daily routine and it becomes second nature.
