As we reach peak training load / taper initiation mileage is high, the load on the system is high & some fatigue is normal. The purpose of this workout is to restore a light & springy quality to gait. The plyometric focus here is on quickness & agility. A different form of plyometrics can be used for power & strength, but that is best done after a base strength has been established and no major events are on the near horizon.
