I've had alot of tendon injuries and have decided to quit heavy weights almost entirely, other than a boxing bag workout using it as a dead weight. does anybody have any suggestions as to some workouts i can do to improve cardio, quickness, muscular endurance and a bit strength, but i don't want too much weight gain as i want to stay in my weight class at 165. My strength is high enough as is, i was benching 225 lbs at this weight before i dislocated half my ribs from a really bad fall in judo from an idiot blue belt. I've got some plyometrics happening to increase explosiveness, but couldn't really think of that many i could do, does anybody know some plyometric excercises i could do? also anything to improve chin, i've been using a judo belt tied to a 20lb weight, and its been working a bit, does anybody know any others? heres the equipment i have to work with. Door frame (for chinups) two focus mitts two 200lb boxing bags one hanging, one free 5-40 lb dumbells 45 lb bench press bar bench press bench regular bench 5-45 lb barbell weights 4 5 pound ankle and wrist weights a small field (50 ft by 25 ft) mats (maybe 10 ft by 5 feet, but can use bigger ones up to 25 ft by 25 ft 2 pairs MMA gloves 1 pair boxing gloves 2 pairs speed bag gloves boxing wraps a whole crapload of judo belts an old judogi 2 new judogi's one boxing sparring partner stairs skipping rope walls (for wall pushups) a 3 foot stick I listed all of the equipment i could possibly think of because i know when i make up workouts i'm usually really inventive, i've used all of these for workouts before, they all work pretty good for something. If anybody knows any plyo, endurance, harsh cardio, or just generally MMA, judo, kickboxing or submission wrestling applicable excercises i could do that would be awsome. I need some plyo for my back, i haven't thought of anything yet (bouncing the weights in one arm row?) thank you for any help you can give me.
