Some stuff i found on Jay Schroeder
The Ultra Fit system of training completely eliminates the need for running as a conditioning method. Instead of running to condition the body, we train the body to be able to run and eliminate oxygen debt through the training system itself.
What is the difference between Ultra Fit training and the strength and conditioning program we presently use?
All strength programs - Olympic lifting, power lifting, or body building - work the muscle primarily in concentric contraction (the shortest length).
Ultra Fit primarily works muscles in there longest and strongest length, by stressing eccentric contraction.
How does Ultra Fit training help reduce injuries?
All injuries are caused by the bodies inability to absorb force. Ultra Fit training is the only training which trains the body to absorb massive amounts of force.
How does Ultra Fit training improve speed and athleticism?
Ultra Fit training trains and strengthens the body to contract and relax the appropriate muscles quickly to facilitate fluid movement
