Thoughts about my workout plan

Hey guys, since my summer break is coming up, I have made a little workout plan that I will hopefully follow in the next two and a half months. I tried to spread the workouts throughout two days, with one day off after the two-day cycle. To get the exercises I need, I use an app on my phone called Home Workout that quite nicely paces the exercises throughout the month. That is why my plan is based on that app (although any suggestions of better apps or an alternative are welcome). I will do the workouts twice a day, once in the morning and once in the evening. I also do each exercise day from the app twice, and since all the exercises are repeated twice in each day, this basically makes it 4 sets which I think is fine. I would like to note I avoid certain exercises such as jumping jacks, knee hops etc. due to an injury I have. Without further ado, here is the plan:

Day 1:

• morning: abs
• evening: arms & legs

Day 2:

• morning: shoulder & back
• evening: chest

An example of the first day exercise routine from the app for each muscle group:

• Abs:
  • High Stepping x20 (which I skip due to injury)
  • Jumping Jacks x30 (skip)
  • Standing Bicycle Crunches x20
  • Mountain Climber x20
  • Abdominal Crunches x10
  • Heel touch x16
  • 30s plank
  • This repeats once more, with a few stretches at the end
• Arms:
  • 30s Arm Raises
  • 30s Side Arm Raises
  • Triceps Dips x10
  • 30s Arm Circles Clockwise
  • 30s Arm Circles Counterclockwise
  • Diamond Push Up x6
  • Jumping Jacks x30 (skip due to injury)
  • Chest Press Pulse x15
  • Leg Barbell Curl Left & Right x8 each side
  • Diagonal Plank x10
  • 30s Punches
  • Push-ups x10
  • Inchworms x8
  • Wall Push-Ups x12
  • Stretches
• Legs:
  • 30s Side Hop (skip due to injury)
  • Squats 24x (I do them really wide with feet turned outward due to injury)
  • Side-lying Leg Lift Left & Right 24x each side
  • Backward Lunge x14
  • Donkey Kicks Left & Right x30 each side
  • Stretches
• Shoulder & Back:
  • Jumping Jacks x30 (skip)
  • 16s Arm Raises
  • Rhomboid Pulls x14
  • 16s Side Arm Raise
  • Knee push-ups x14
  • Two stretch sessions
  • 30s Arm Scissors
  • Rhomboid Pulls 12x
  • 14s Side Arm Raise
  • Knee Push-Ups 12x
  • 30s Cat Cow pose
  • Prone Triceps Push Ups x14
  • Reclined Rhomboid Squeezes x12
  • Prone Triceps Push Ups x14
  • Reclined Rhomboid Squeezes x12
  • 30s Child's Pose

I know this is a long post so thank you for getting this far. Any opinions on this schedule are more than welcome. I haven't included cardio since I am not able to do any due to the injury that I have. The workouts in the app aren't always like the ones I listed, they get progressively harder with each day. Do you think doing all the in-app days (an in-app day is, for example, the one I listed under legs or arms) twice is too much? Should I only do them once? Thank you for all the opinions
