The Cardio Training System is designed to build aerobic fitness that supports recovery, consistency, and long term performance.

Programs in this collection are built using the MHR Cardio system, where intensity is controlled and volume is applied progressively to improve endurance without excessive fatigue. Cardio is treated as a foundation, not a punishment, supporting all other training goals.

Cardio training within this system focuses on:

• Developing a reliable aerobic base
• Improving endurance and efficiency
• Supporting recovery between training sessions
• Maintaining consistency through busy periods of life
• Fitness that transfers to daily activity and long term health

Programs may use a variety of modalities including running, walking, cycling, rowing, or machine based cardio. Each program clearly explains how aerobic work is structured and progressed within the system.

This collection suits people seeking improved fitness, health, and endurance through controlled, sustainable cardio training.
