Awright, fitone. It looks like I’ll be the first one to answer this. Ko is currently in sunny and warm Puerto Vallarta and will be back on Saturday - I, in the meantime, am home holding down the fort with our four parrots. Oh, sorry way too much needless info. But, hmmm. Torn ligament? And his Hapkido Promotion in in June - I trust you have something in mind that will work his upper body (especially to maintain punching power) when he can resume upper body training? Seems like what would be good for right now in training is focusing on mobility. That would require training specifically to execute fast offensive technique AND fast defense. In any martial arts system, superior footwork is the cornerstone. You gotta learn to get into your opponent’s “kitchen” and strike fast - keep 'em busy, moving - and also know when to move defensively. You can’t allow your upper body (shoulders, head, eyes) to give off signals to your opponent as to your next move. So, in a way, this injury could be a godsend for your client. May I suggest incorporating basic plyometric exercises? I have a book by Donald Chu that is very good - and I know of another book about plyometrics, but haven’t seen that one, so I can’t really tell you if it’s good or not. I know footwork drills may seem boring, but those were some of the toughest training sessions for me. You work so hard on making your movements look effortless and you have to gradually work in speed, and pinpoint punching/blocking techniques. Ko will be calling me later tonight - I’ll pass on this question to him and see what he has to say. He’s more knowledgable on this topic, while I’m more of the “muscle-head”.
