i have excellent explosive power and pound for pound strength, but my muscular endurance is horrendous. this is never more obvious than when rolling or hitting the mitts/heavy bag at full force. i rarely endure the entire round of striking as either my shoulders or chest will give out, and my hams and back/biceps give out when rolling much faster than my cardiovascular. how can i increase muscular endurance without sacrificng power? is it possible? if i can't win early i have a very difficult time winning at all.
It sounds like you need to spend more time hitting the bag. It's a lot like wrestlers who try and build up their sport stamina through exercise and it doesn't quite work...they usually end up puking all over the place (slight exageration). However, BeWater passed this onto me a couple of days ago that's inspired by Dan John... 1X20 snatch drops 1X50 snatch high pulls from the high hang 1X20 snatches from the hang 8X5 over head squats You could start incorporating an endurance day in your workouts or start incorporating things like dumbbell swings for high reps, etc
I think over on T-Nation there is a great article called GPP ASAP by Chad Waterbury. http://www.t-nation.com/readTopic.do?id=468125 This shouldn't hurt your strength any but you will definitely improve endurance.
I'm sorry bro, but I think you might have to change your name to something like "Faster than you, in a short race". I kid, I kid. I agree with Samurai. This may be one of the rare instances where a period of lighter weight, higher rep (anywhere from 15-100) work is appropriate. More sport-specific bag work or groundwork would be fine. 1 or 2 days a week of this kind of work should be plenty. I don't know if I'd go with an exact G.P.P. routine like Blake suggested, only because G.P.P. is more of a general conditioning exercise. It's more cardiovascular endurance, not so much muscular endurance. If you're certain it's not your "wind", then Waterbury's program wouldn't be correcting much.
