Training in Heart Rate Zone 5
Benefits of Zone 5 (90-100% MHR) Cardio:
✅ Improve max speed
✅ Increased Anaerobic Enzymes
✅ Increased Phosphocreatine
✅ Improved Capacity for Repeated Max Efforts
To really develop maximal speed you need to train close to maximal speed.
📊 This requires short high efforts with adequate rest that is about 12 to 20X as long as the work bouts.
Cut rest too short and you’ll quickly end up down to zone 4 and miss out on developing top end speed.
Zone 5 is hard work💪🏼
