dim mak works pretty well... or so im told.Haha I agree. I meant to say bend, I have got to spot working 20 hour days. If they already took boxing what would some of you guys suggest, for a confidence boost and general exercise.
serious answer- if someone already does boxing, then you probably dont need an additional martial art. you probably also dont need a high impact sport since boxing tends to strain the tendons and ligaments enough. i would recommend swimming. great cardio, non-impact, also helps loosen the tendons and ligaments and help them repair.
