I have been interested in joining a boxing gym for quite some time now. I have narrowed it down to a few gyms, and before I go choose which gym I would like to join I would first like to increase my fitness as to maximize the benefit I get from joining the gym.
With regards to my strength I consider myself slightly above average. I can do 10 proper pullups, 15 chinups, 60+ pushups, ~20 dips.
I acknowledge that my greatest weakness is lack of stamina. I can barely run 2km. This lack plus weak asthma(I breathe really heavily after just warming up, but I'm not tired?).
At what point am I fit enough to pursue boxing. What fitness programs out there cater to my weakness to help me improve to that level of fitness.
