Of course. His breathing power is so much bigger now. Probably out taking a 42 km sprint as we speak.
ahhhh, the 42km spints.... I would have thought he would be on the 43km sprints by now...uphill I looked up some info on it and bumped into this forum: http://www.runnersworld.co.uk/forum/forummessages.asp?UTN=8225 Some impartial reviews on it. Some posts in particular:
I bought it myself today I can definitely see this being of use to me, I tried level 4 and the out breath feeling I got is very simillar to the type of out of breath feeling I get when running. It isnt so much my muscle endurance or even my heart rate, its mostly my breathing. I'll see how it goes the next few weeks. I researched about it and read some posts from other forums regarding the product, seems to be mixed opinions.
