[quote author="Scott Thomas" date="1285788113"]CF has commented on use of heavy sleds in Bolt’s training program saying that it may lower the requirement for lower body weights. I think he mentioned that he himself would do similar to what has been mentioned here (decreasing load with increased rep distance).
Could you expand on this? Do you have information about the sled/hill work used by Bolt?[/quote]
There are some photos of Bolt with some weight plates on a sled running in trainers. Asafa does similar with up to 50 lbs per Stephen Francis. They do them from blocks as well in flats.
