Kris Stallenberg 75-min Z2 (Endurance) Pushing #08 This workout blends steady Zone 2 endurance with short, high-power 'stomps'. These 15-second bursts into Zone 6 (Anaerobic Capacity) are designed to recruit fast-twitch muscle fibers without creating significant lactate buildup, teaching your body to handle sharp accelerations or power over short hills. The core of this session remains aerobic, aligning with the principles of Coggan Power Zones for building endurance. Focus on recovering quickly back to your Z2 pace after each stomp. bike
