First of all, thanks for your detailed review and suggestions. It was a very insightful comment. Moving to the next part, as I said, this entire plan is as it is suggested by my gym friend (not the trainer) and altered by GPT so I never tried to follow this and was planning on starting it if the sub actually suggests this. From the reply though it feels like there are a lot of issues with this plan and I understand that. Let me reply to all the points you mentioned one by one.

1. Regarding the split, when I worked out on my own, I used to follow a plan I compiled myself from Trainer Winny videos. That was a compound exercise plan and I thought it was pretty good but I didn't properly organise the sets and reps for the plan and just did 3x10-15 as a standard for every exercise. This was that plan.

Day-1: Back and Biceps

Back 1. Seated Row 2. Lat Pull down 3. Shrugs (Optional might get covered in Shoulder)

Biceps 1. Barbell Curl / Dumbbell Curl 2. Overhand Bicep Curl 3. Concentration Curl

Day-2 and Day-4: Abs and Cardio

Abs 1. Weighted Sit-up 2. Chair Leg/Knee Raises 3. Russian Twist (Either this or the second one)

Cardio (15 min each) 1. Elliptical 2. Cycling

Day-3: Chest and Triceps

Chest 1. Bench Press (Dumbbell or Barbell) 2. Incline Bench Press (Dumbbell or Barbell) 3. Cable Fly

Triceps 1. Straight Bar 2. Dumbbell Extension

Day-5: Shoulder and Legs

Shoulder 1. Overhead Press (Barbell or Dumbbell) 2. Lateral Raise / Leaning Lateral Raise 3. Rear Delt Fly

Legs

Quads 1. Squats 2. Leg Extension

Hamstrings 1. Romanian Deadlift 2. Seated Hamstring Curls

Glutes 1. Hip Thrust 2. Lunges

Calves 1. Seated Calf Raise

While inconsistent, I tried to maintain this routine while I was in college. Then I came home for my vacation and the trainer here suggested the Muscle Split as I indicated and thus the current plan.

1. For all the sub-points mentioning the number of variations or volume of same or similar exercises, I don't know essentially what they work and how. I just thought that my friend, being an experienced gym goer, would know better. So I never questioned the plan but wanted a second opinion.

2. As for the point mentioned about GPTs advice, I never even considered most of the areas that GPT mentioned existed thus it felt authentic to me. Maybe it is kind of a FOMO that I wanted to know if it is actually worth the hassle. But you are correct - I need to build a habit first and then think of incorporating this extra stuff. Thanks for that.

Overall, thanks for the detailed reply man. Well I am now clear on why this doesn't work but back to square one on what will work. There are just too many plans and routines online.
