Kris Stallenberg 120-min Z6 (Anaerobic Capacity) Easy #09 This workout combines a solid set of anaerobic intervals with a block of pedal stroke drills. After the main high-intensity work, we'll use the long recovery period to focus on technique with single-leg drills. This combination builds top-end power and then refines the efficiency of your pedal stroke, making you a more effective rider. bike
