weights perhaps? 3 sets of 15; or like we do in my gym, do speed drills where you throw as many punches as you can in 1 minute without stopping
Sure, sports specific exercise. Punching the bag (drills for example), shadowboxing, pad work, sparring, things that involve punching.
And you're saying weights don't work..... you're fully extending your arms with weight resistance... helps hold up your arms, and the constant back and forth motion helps with punches.
you're also causing muscular imbalance which will lead to injuries, especially with the hypertrophy rep range you suggested.
weight training is perfectly fine as long as its light weights and higher reps to strenghthen what you have without having to build more muscle.It burns fat. I would say the best way to condition your arms would be to keep doing the boxing stuff you have been doing.After a while you will laugh at the newbies that go through what we all go through at the start of our training career.:good
Muscular imbalances only occur when you dont know what your doing or you stick to the same exercise with no variation.
Light weights DOES NOT burn fat. Heavy weights burns fat because it increases your metabolic rate. Light weights frankly are pointless and only serve to warm up a muscle and get loose. Too many people recite this same tired line without knowing that resistance means BETTER results. Raising your arm a thousand times wont do anything other than stimulate slow twitch fibres which to be frank is pointless. It will not increase your performance in the slightest in comparison to the effect more resistance has on fast twitch fibres.
