Champion you say you are 15, a wise man at that age.
back in the 80’s a 15 year old girl who was doing the same type of program which included a leg press won a 12 months subscription to a gym in a bench press comp, competing against body builders etc. 3 lifts, percent of bodyweight. In the weight room she did matrix with a max of 40lb plus bar. her weight was 60kg and lifted 1.5% of her weight to win. She was found by some talent scouts and the story ends there.
BTW she used to come 2nd at state behind Jana Pittman and she has won at world champs, youth, junior and senior.
To train smart doesn’t always mean heavy.
