What should I do to achieve excellent conditioning for amateur boxing?

I'm 6'2, 234lbs, natural heavyweight, hard hitting, so far my stamina is good but not great. I'm focusing on conditioning myself now, at boxing we do circuits which are tough but I'm talking about running, swimming and that stuff. How many miles is good for a run, how often to run this? And how long to swim a week.|||First of all, you've got good size, but I don't want you to get cocky, but rather confident. Breathing is the most important thing to learn to do correctly and regulate it. Conditioning is more than 70% in amateur boxing. You could be the biggest guy there, with the best punch, but if you run out of gas before the end of three tough rounds, it's worthless. ROAD WORK is most important. Not just running, but miles of endurance building road work. Run, stop, shadow box, move around, keep running, not sprints, but a good steady pace that keeps you breathing through your nose, not your mouth. Learn to pace that breathing as much as possible. Secondly, don't be a head hunter. That body punch both left and right can do just as much damage as the big punch to the chin. Don't bully so much, but know how to use your punches. My son is 6'4" 235 and I taught him to box tall. Reach, a great jab, movement, not Ali shuffling , but the ability to use angles on your opponent.





Keep your roadwork constant, but vary the locale to keep from getting complacent or bored. Good luck. If you vary the roadwork do 5 miles or more daily, or at least every other day. Breath...don't forget to breath and keep yourself under control. In the gym, beside your regular bag work, sparring, do the box exercise for your legs and again breathing. It's like a stepper. Up one side of a raised platform, say 12 inches high and up and down on this box will be lots of stain on the legs. Good exercise for endurance and again breathing.|||Cardio is key in conditioning. Swimming, Running, and Climbing are very valuable assets for increasing your stamina and cardio.


Muhammad ali was running 4-10 miles per day, weeks before fights.


But if you have no fights upcoming, the best way to stay in shape is to keep a routine for a week and then increase the routine, start off running 3 miles per day for the first week, with 10 laps in the pool, and 1 hour of climbing. The following week Increase each of these, Running= 3 1/2 miles, 12 laps, and 1 1/2 hr of climbing.
