@madscientistofmuscle: Roller Blade Interval Sled Pushing (90 lbs)... this is phenomenal conditioning and lower body training. Naturally, you'll need to have a sled and roller blades and enough skill to actually push without wiping out. I used to be a speedskater back in high school (short track) and would have loved to have trained like this! I went for 1/3 of a mile, with short rest periods between work intervals until I was done with the distance. After the sled pushing, I decided to go for some moderate speed training - about 80% of a full-out sprint. --------------- Want bigger legs FAST? Try this free 3 week specialization program...
