at certain times, when running an intense drill or running there are atleast a few seconds, probably at the end when you just feel like you cant handle it anymore - you gotta stick with it. sure you feel like quitting right then and there, but afterwards you feel accomplished and it seems like there wasnt any pain at all. About your running, you just have to practice.. running. The heavyweights might of had been cheating like someone else mentioned, or they've simply been running alot and are used to the pain. And about your coach, my coach says the SAME thing for every drill we do. He's just trying to motivate everyone, and if you're trying youre best he'll understand that (well most do). Try breathing evenly and deeply when you run, and stretch good (important).
Now about my third day. Same running as the day before, and we did more conditioning inside.. wheelbarrow with partners, crawling, hand walking with partners, spinning,etc. moves, review and some new ones. So it was pretty easy till the end, when the coach suprised us with some cardio. did the bike, stairmaster, steps, this other stairmaster? you move foward and your hands hold and move with you by holding the bars. All of it was easy, till the abs.. i found my weakness. Well actually crunches werent bad, but then we had to do two excercises that i was struggling with. You had to put one of those big bouncy balls in between your legs, then raise your legs 90 degrees, and the second was almost the same - but you throw your legs up and your partner pushes them down, cant touch the floor. I was struggling with the first one.. was raising only like 35-45 degrees up.. then the second time around.. i found out that i have alot of trouble doing leg lifts... i was trying to pull my legs up and my the guy i was working with was one of the captain kids and he kept yelling to try harder, and it was massively hard. What muscles does it train? I'm gonna start doing basic leg lifts or something at home now, and work on those so that doesnt happen again.
