The workouts in Disc 5 pull together all the work you’ve done so far. The interval intensities return to Steady State and Tempo levels but keep the total workload high with longer efforts, and the whole Progressive Power Series ends with another shot at the CTS Field Test so you can measure and clearly see how much progress you’ve made. Nothing makes you faster on a bike then increasing your overall power. Carmichael Training Systems Progressive Power DVD’s are designed to do just that – use them independently, or combine all 5 DVD’s, to get 16 power workouts that studies show can increase your overall sustainable power by 12% (Klika, et al., 2000). Each DVD contains three 1-hr workouts. CTS Field Test disc is included with each order.
