Damn all that and you're still only 17? If you're still passionate about it, keep going with it man. You still have a lot of time to improve. If you still want to box, then you should put as much time into it as possible instead of doing another sport. A lot of things will click and come together with age.
[QUOTE="reznick, post: 18277877, member: 54206" If you still want to box, then you should put as much time into it as possible instead of doing another sport. A lot of things will click and come together with age.[/QUOTE] This. Nick and Nate Diaz train for and participate in triathlons along with their pro MMA career, but they're freaks who are also full-time fighters. A few of the things you said can be integrated into your training, a few crossfit style workouts a week for example, but some would be silly to attempt along side boxing if boxing is your main sport. It's definitely possible to do multiple sports as I said above, but it's tough and takes a lot of planning. Put everything into your boxing.
I think you guys are right, i would stick to the boxing routine and then start with some kind of work in the gym. By the way, the other two guys that qualified for the youth world championship, couldn't go there since there was a problem with the passport of our couch that is cuban.
Just to add to the yoga. With boxing the muscles grow taut because they are used when contracted and then asked to explode to generate massive power. Yoga allows you to stretch those same muscles and more, yoga is also great for fostering good breathing technique, and funnily enough this is what I am finding most useful for sparring. In yoga you consciously think about how you are breathing, when you translate this into the ring it encourages smoother and deeper breathing that means you don't get puffed so quick. Taken about 3 months to really see the benefits in terms of breathing, but the benefits of stretching properly under informed supervision is immediate.
Swimming. Yes I know it's hard to learn at the start but bloody hell it works all your body. Back, shoulders, arms, legs! A WHOLE BODY WORK OUT!
I would add that yoga/mobility is not something you have to recover from so you should be doing that for sure. Should also foam roll/lacrosse ball/myofascial release stuff with that. You won't have time to box and to BJJ so I don't think that makes sense. There would not be enough transfer of training in bjj to boxing to make that worth it. Crossfit would make the most sense IMO because you don't really have time to separate strength and conditioning when you are already have to invest so much time in boxing too. Crossfit would benefit your conditioning, explosive power and strength endurance so it will all transfer to boxing. Ideally, I would look for a crossfit gym with some coach that has some idea of the needs of a fighter. Investing tons of time in snatch technique isn't going to make much sense.
Very interesting background, I quite like the amateurs so if you're still on forums; how are things going now?
