Slow progres on core and pull muscle
so im 14 and started puberty like a year and half ago. trying to get taller and build muscle but not really caring about legs
right now i can do:20 push ups, 6 pull ups, 3 chin ups, idk about core stuff never really tested it
the problem is my pull ups are progressing so slow and my grip is too bad. like 4 months ago i could only do 4 and now im at 6,can only hang about 30 second and my hand is burning after.
i got 7 days a week free so i can train whenever. just want a plan that helps with height (heard hanging helps?) and gets my pull ups and core stronger
any tips? please dont be toxic im new and dont know a lot about stuff
