My final cool-down set was done without the PB and that was awful - it felt as if my legs were hauled into the depths of the pool! I can see why PB training is controversial as although I've had great arm workout and been able to focus on stroke technique I've been misled into my speed. I think I'll do a few floating drills next session to focus on keeping my legs up without the need to kick. The PB has really highlighted the importance of streamlining to me.
