Is there a relationship between hypertrophy and endurance?
I am aware that high reps are believed to produce both. However, are increases in hypertrophy necessary for increases in endurance? I am asking because I am on a caloric defecit, and I do not expect significant gains in muscle mass. But yet, I do some high rep training for endurance. So, can I have significant endurance gains without significant mass gains?
Thank you for your time.
