Are you training for professional fights or something? That much weight training seems strange to me also but every coach is different, and the proof is in the pudding as they say. Our club website is absolutely, diabolically bad, but here it is anyway:
http://beehive.courier.co.uk/default.asp?WCI=SiteHome&ID=15054&PageID=95465 Our only boxer of real interest is Janie Brashill, a female boxer who has achieved quite a lot at the national level (to the point where there are no real fights for her left in the country). There's a bit about our club at the end of this ABAE newsletter as well, you can download it here:
http://www.abae.co.uk/News_Archive/2009/August/News_items/ABAEnews_August_14th.asp (pdf. file) By the way, I'd describe our club as at the casual end of things, so possibly I'm not the best one to comment on stuff like this - although I intend to go as far as I can, personally.
We just use trainers for running on the beach, no ones going to be arsing about spending money on extra pairs of shoes just for that. Running is probably the best way to raise your fitness if you ask me. I got woken up by my drunken housemates as about 4:30 last Saturday early morning and couldn't get back to sleep so I went and ran about 8 miles flat out, almost killed me but the next sparring session felt like a complete walk in the park, I didn't even get out of breath
As a side note I weighed myself at 70Kgs today, so I've lost 4-5 over the past two weeks. Christ knows how or where it's coming off though, I'm eating a lot more carbs as well
Edit: watched the De La Hoya Vs. Pacquiao fight today from last year - what the hell was De La Hoya thinking??? A 35 year old well past his prime against the best of the best? The fight should have been stopped a couple of rounds sooner if you ask me, he was getting battered.
