I'd say 90% of ALL fighters jump rope to a degree. You dont need to be a master at it like SRL, you just need to put the work in. Do your standard 15-20 minutes of rope work per day and thats all you'll need. If you cant jump rope to save your life, do jumping jacks and knee highs while holding 1lb weights in each hand. Jumping rope is only one piece of the puzzle.
I can't possibly imagine how come consummate, top professional fighters like Ricky Hatton, David Tua or any other mentioned name wouldn't do what is a standard training procedure in any boxing gym. You have a clock with a bell in most gyms, everybody switches activities such as punching the heavy bag, working with the fast bag, shadow boxing, jumping the rope, other general gym workout ( push ups, benches, pull ups, et cetera) until the period of time ends and the bell rings, and so that nobody takes time off and unwanted breaks. Of course sparring and outdoors training have different procedures ( more appropriate with each fighter and thus, with varied workout routines) but I cannot see how can guys at that level skip that. Even Riddick Bowe jumped the rope and ran slowly when he was above 240 lbs... You don't have to do tricks like Mike Tyson used to but I would say 100% of fighters jump the rope, I don't see a legitimate reason not to.
I've seen fighters' workouts all over the world -- some unique to a particular place. But I've never seen floorwork as eccentric as Wlad Klitschko's. He and his former German trainer looked like a syncronized swim team. The trainer constantly monitored Wlad's heartrate.
Evander Holyfield was the first to use Fitness Gurus and if you still watch his fights, wonder what conditioning trainer Tim Halmmark does on Holyfield's corner??? Holyfield pushed it too far, forgot about sparring/boxing and payed heavily against Double M in 94... Wlad's team was probably taking the same approach, Holyfield had heart ailment back then and looks that Klitschko was not far from it against Brewster, the first time... I got to know Wlad used to make swimming butterfly strokes so the comparision is not that awkward.
Calzaghe says he doesn't skip. It's probably due to his Dad who is one of the more progressive trainers, who don't slavishly follow the routines of the old timers on the basis that 'that's what boxers have always done', without actually thinking about the benefit in relation to time possibily spent doing something else, ie improving ones skills. I'm a boxing coach and personally think that other than a nice warm up, skipping is a waste of time. As opposed to most sports, boxing training seems to be rooted in the past, without consideration of modern training techniques/excerises/nutrition etc
In his book he says it's because he can't think of anything more boring, that's why he doesn't skip much. What are modern training techniques/excersises/nutrition? Calzaghe runs 6 miles a day, doesn't lift weights and eats cake after he weighs in, he really rebels against his dad then if Enzo is progressive :huh The calzaghes are as old school as they come.
Jumping rope is not necessary. It is very good for the stamina but for the specific work it's useless. You are obliged to include it in your training sessions though cause your boxers will ask for that : the "legend" with the Rocky films, the videos of the old boxers etc. But in fact it's not a fantastic exercise. Far better exercises are now available to work the rythm, the footwork etc.
