So here we are, im a volleyball player, who's in love with basketball lol (played it all summer about 4hrs per day that helped me alot to loose my weight)

I want to increase vertical so i can spike good and dunk a basketball (my dream). Here are my stats:
AGE:17
HEIGHT:184cm
WEIGHT:75kg
SLEEP SCHEDULE: Because my highschool got 2 shifts, i go to school for one week in the morning, then second week afternoon, and its switching in whole year, if you understeand me, so when i go to school in morning i use to get in the bed before 23:00 and get up at 07:00, when i go afternoon its about 23:30 and i get up at 09:00.
BODY TYPE: I was 85kgs but im 75 now and i got to work on my muscles, my upper body is solid, i have to work on my chest and arms mostly. And about my lower body i got kinda big quads, and solid calfs, i have to work on my hamstrings...
GOALS: Heh... i would like to increase my vertical up to 30'' for short term and to 35-38'' for long term.
CURRENT ABILITY: My vertical is now about 24'' with one leg jump and 22'' 2 feet jump.
INJURY HISTORY: I can say that i havent broke any bone in my life and i wasnt suffer by any kind of legs injury in my whole life.
TRAINING HISTORY & ACHIEVEMENTS: Im training volleyball for about 6 years now, and it wasnt so serious at the beggining so trainings were easy and it was hanging around with my buddies and screwing around. For last 2 years we are training constantly and we were achieveing good results. I got very low VJ in comparing my friends who (most of them) can jump over 30'' with ease. So this is the reason i want to work and train hard! When i started aa3 i never passed any training i worked everything like it says so and with 110% of my strength, i havent seen results untill week 6 but i was still doing no matter i havent gain not a single inch, so after week 6 i got my first results. Anyway im prepared to do any kind of exercise including weight training starting from the next year. I also lost 10 kgs over 6 months and im feeling much lighter and better now

CURRENT ACTIVITY LEVEL AND/OR TRAINING PROGRAM: I go to my volleyball training ( monday, wednsday,friday), sometimes i miss some training because i dont want to overuse my muscles because im doing air alert constantly.
BRIEF OVERVIEW OF CURRENT DIET: I dont drink craps like Coca cola or Sprite... I drink a lot of milk, i drink natural juices sometimes. When im on some birthday party or celebration i drink beer mostly. I eat meet

fruit and vegetables, ham, eggs, ketchup ( with almost every meal), sometimes some sweets, cakes etc... I dont do any diet program.
IMPORTANT ACTIVITIES: Got to work air alert on mondey, wednsday,friday, and on other weeks: tuesday,wednsday,thursday. Also volleyball training: monday, wednsday, friday, but i skip some trainings because of air alert and we dont have any league runing in this season.
That would be it, if you need any more informations feel free to ask.

I have few questions. Can you explain me this "S1 or S2 or S3 etc mean supersets... anything labeled S1 means do all those exercises back to back, then rest after the final exercise", and what should i use as a protein? And i think i wont able to do these kinds of pull ups cause i dont have anything to hang on in my flat. All other exercise are doable.
Best regards!
