[QUOTE=PhilG;230384]Interesting, I would have thought that even at that level concentrating on 30m would be a bit too short, how would you progress this ?
Also, would 15 mins recovery not be too long bearing in mind at her level the CNS output will not be very high.
Progression could be out to 2 x 80m after the 30s,however real progression is through the increase in speed/ intensity of the workout.
one way to increase cns output is to increase the recovery.
