Always hear and see guys talk about training twice a day 4 times a week or more, imagine that shit, running in the morning, lifting weights and then sparring or hitting pads. Do you know how fucking sore your body would be if you would do this without the help of some sort of recovery ped or microdosing test. Your body would literally not have enough time to repair all the microtears in your muscles and in turn your body would start breaking down, testosterone levels would drop, cortisol levels would go up, muscle would start breaking down... It's simply not possible, dont believe me? Try it, not for a month, just two weeks and see what happens. Take it from someone that did two sports when i was a kid. Played football(soccer) and after that i changed clothes and went to track and field. I was sore all the time and i was a kid, kids can get away with more since they have an abundance of growth hormone and they dont have as much muscle making theme recover much faster. And i wasnt lifting any weights back then either. They're all on steroids. Dont believe the natty athlete hype.
