The Importance of Flux Training

A robusted athlete is an athlete who can handle a bit of variety of races, pieces, shifts, changes. And one of the ways to throw it in the training is to vary the training up and use flux. Bob Schulstein's pre-3040 drill: 10 by 100 meters at 3k effort with slow down walk turnaround recovery back up again. The more you do at it, the better you get at it. But only if you do it every day on the regular.
