I'm a freshman in HShigh school. I've been workingoutworking out for a little over a year now I've. I've finally reached a max of 55lba 55 lb curl with one arm and now I would like to increase bicep size for my arms, which are only 11.5 inch when flexed. I would also like to increase endurance could. Could anyone give me an ideal weight and rep range for increasing size and endurance?
