Kris Stallenberg 60-min Z2 (Endurance) Medium #06 Build muscular endurance and strength with this low-cadence Zone 2 workout. By reducing cadence, you increase the force required for each pedal stroke, which helps develop strength without the high cardiovascular stress of harder zones. This session targets specific muscle fiber recruitment while staying within the aerobic Z2 defined by Coggan Power Zones. Focus on a smooth, powerful pedal stroke and avoid rocking your upper body. bike
