Hello my name is Henry and I am currently in self improvement and am about to turn 15 years old. I want to mainly gain strength and some muscle too, I am just getting started working out and have not been consistent so far, hope you have a great day :)

If I want to increase my pull up numbers, should I train to failure like in the new vid w emom/drop sets or should I go for strength with form, currently at 8-9 chin over bar pull ups.
