Zee, When I fought for my world Title is Atlanta Georgia, my manager sent me to train with Tim Hallmark, Hollyfield's fitness trainer in Houston Texas. He would push me in different areas of training and we would keep track of my heart rate, BPM. count the BPM for 6 seconds then ad a 0. 10 Beats in 6 seconds would be 100 BPM. this was the way we kept track of my endurance improvement. We did many different exercises and after each one when we were at rest, i would measure my heart rate, BPM and then when i would start up again after a minute(the time for rest in between rounds) I would measure it again, to see how fast my recovery was, how much i could lower it before i began again. it was excellent in the way i would be able to see improvement in my endurance. 1. weights and cardio mixed. do a complete set of exersices on the machines then run for about a minute or two. then back to another set, (circuit training, light and high reps) then run again, start off with two sets then build up. and after you do your next set of weights do a few minutes on the stationary bike, then the next set do the versaclimber. break it up. remember, one way you can stay motivated in your training, the body, mind and spirit has to work together, challenge the mind, strenthen the body and push the spirit. with consistancy you will see results in those areas. always record your training, the results, what works and what doesn't. 2. In a pool wearing a wet suit that keeps you just above the water and shadow box, punching and kicking, excellent training. remember to keep track of your heart rate. you control your heart rate, don't let it get out of control. force yourself to breath in as slow as you can then exhale slow as you can. this will lower your heart rate so that you are able to maintain a level of consitancy with executing good technique on everything you do. these are just a couple of techniques that's worked for me. anyway i hope this helps. Good luck, be smart in your training. Peace.
