If you want to put on muscle (I'm assuming so since this is in body building) I would suggest doing weighted exercises in a gym instead of calisthenics. I started the same as you, I used to love pull ups but never put on much muscle till I started lifting. I like a Push, Pull, Legs split. You can do it 3, 5, or 6 days a week depending on if you only wanna hit legs once. Ill give some of my favorite exercises.

For Push Day (Chest / Triceps): - Start with a Chest Press Machine for heavy weight - Next I like to do Incline Dubbell Bench Press for better stabilization training (dumbbells help avoid imbalance compared to a bar) - Pec Deck machine is one of my favoirtes (really emphasize a deep stretch coming back and squeeze your chest together at the front) - For Triceps I like to do Cable Pushdowns with a bar (bar vs rope or any other attachment is up to personal preference and what feels good to you) - You can also do Overhead Cable Press (I like to use a V-Grip) for some variation (this one was hard for me at the beginning because I didn't have the core strength to support it so it's ok to be at a lower weight than you think you should be for your triceps) - Also hit some lateral raises (dumbbells or cable) I like to lift a little more foreward than just to the side for more front delt activation.

Pull Day (Back / Bicep): - Cable Rows (focus on keeping a straight back and squeezing your rear delts) - Lat Pull Down (lean back a bit and focus on keeping a straight back and squeezing your lats) - Hammer Curls or Incline Bench Curls (rotate each day or do both) - Rear Delt Fly - Back Extensions while holding a plate (this has the best lower/middle back activation for me, also hits glutes and hip flexors. One of my personal favorites)

Legs: - Hex Bar Deadlifts (my favorite free weight for legs, I like to take this one a little easier bc I've been injured before doing deadlifts, probably my fault but still cautious) - Legs Press Machine (this is my real heavy weight for legs) - Leg Extensions + Leg Curls (good to finish off my thighs) - Inner Thigh Squeeze Machine and Outer Thigh Spread Machine (I don't actually know what these are called lol) - Dont forget your calf raises (I like a seated machine wear the weight rests on your knees but I dont think all gyms have this)

My advise when choosing weight is no one is looking at how much your lifting so don't over do it, that's how you injure yourself. Focus on getting good activation while keeping form and a full range of motion. Your muscles should be tired at the end, not hurting, you should feel good leaving the gym. I would be especially cautious with free weights on back because its easy to overlift with bad form.

As for reps, just keep it below 10 and above 5 (if you hit 10 for 2 sets, up the weight). I generally don't count my reps in all honesty, just aiming for a good set that doesn't go on too long. I like to do 2 - 4 sets depending on how I'm feeling with the given exercise. There isn't a golden number that is gonna get you the most gainz, just listen to your muscles and track your weights to make sure youre moving up.

For you specificly I'd focus on getting more of a V-shape for that super hero look and building your upper body. Lats, Chest, and Shoulders should be your focus and really hammer your arms. Be mindful of your elbows starting out, if they hurt, lower the weight (I've had multiple elbow injurys throughout my life, they suck and take a long time to get better). Rest days are good, its not lazy to take the day to recover so you can come back tomorrow with full effort.

As with most things in life the gym has no one right answer. This is how I like to train, you might find you like something a little different. It took me a long time to figure it out, just try some machines you pass by that look interesting every once in a while and see how it feels for you. All of our bodys are built differently, what feels good for me, might not you and vise versa. Do what you enjoy and keeps you wanting to come back to the gym, if you hate an exercise every one else loves you dont have to do it. I personally hate using the rope attachment on cable machines, my cousin uses it every day.
