Is this a good Workout schedule?

So I will soon be finished with chemotherapy for cancer that I had and I want to live a healthier lifestyle. I used to workout alot so I know what it takes for the most part. My goal for the next few months is to really develop my arms, shoulders, and legs, with a little bit of cardio (something I neglected in the past). Im aware of the necessity for mass protein intake and a healthy diet that includes veggies, fruits, whole grains, dairy, etc. So don't inform me on that please. Considering im trying to build mass im also aware of the low rep heavy weight fact and proper form so don't inform me on that either. All I would like to know if this is a good schedule for my goals.

Day 1

Muscle: Shoulders

Barbell Shoulder Press (3 sets to failure)

Seated Arnold Dumbbell Press (3 sets to failure)

Front lateral Raise (3 sets to failure)

Side laterals (3 sets to failure)

Barbell upright row (3 sets to failure)

Shrugs (3 sets to failure)

Day 2

Muscle: Legs/Biceps

Leg Press (3 sets to failure)

Leg Lifts (3 sets to failure)

Seated Dumbbell Curls (3 sets to failure)

Close Grip EZ Bar Curls (3 sets to failure)

Hammer Curls (3 sets to failure)

Reverse Grip EZ Bar Curls (3 sets to failure)

Day 3

Muscle: Triceps

Close Grip Tricep Press (3 sets to failure)

Skull Crushers (3 sets to failure)

Seated Tricep Press (3 sets to failure)

Day 4:

Muscle: Cardio

1 hour of biking (will improve as I get in shape)

This is just a basic schedule so far but It is my game plan for the most part. I didn't include chest because I feel it is already developed as I used to do a lot of benching in the past so don't worry about that. If you could please tell me what you think of my schedule I would really appreciate it. I'm open to criticism so hit me with what you got.
