Just a quick question, someone may be able to shed some light.
Sprinters always have a serious physique, very strong, in the upper body in particular.
Why do they focus on this? Is that strength required for physical endurance or something? One might think its in their legs that they want that strength.
Anyway the reason i'm asking is because, well it makes sense to me that this would translate well for a kickboxer, the athlete powerful upper body physique.
Not for power in the punches necessarily but rather that physical endurance to keep going.
Even with very good cardio I find sometimes I can loose momentum in a bout when it starts to get tough and I really feel it around the upper body. What steps would I take to improve this?
