How to Build Cardio for Boxing: Endurance Training for Amateur Boxers

Aspiring boxers quickly learn that superior conditioning—being able to produce, recover, and repeat high-intensity bursts—is as important as technical skill. Research shows boxing is 75-80% aerobic, with much time spent above 90% of max heart rate during sparring and bouts¹. Yet the sport’s defining challenge is repeated anaerobic flurries, so your training must develop both a high aerobic ceiling and red-zone dominance.

Understanding Boxing’s Endurance Demands

Building an Aerobic Base (“Roadwork”)

Long, steady efforts—traditionally called “roadwork”—lay the foundation for ring endurance. Aim for 2-3 sessions per week of:

The Pedestal app auto-calculates your zones and highlights Zone 2 sessions, adapting to daily fatigue and terrain so every roadwork run truly builds your base.

High-Intensity Interval Training (HIIT) for Boxing

To master those final flurries in round 3, integrate anaerobic drills:

Research confirms interval-based circuits significantly improve both aerobic capacity and muscular endurance in combat athletes⁵.

Periodization: Structuring Your Conditioning

A block-periodized approach maximizes gains and prevents burnout:

Periodization ensures you peak in aerobic capacity and red-zone power when it counts.

Monitoring Intensity with Heart-Rate Zones

Use a heart-rate monitor to guide every session:

A balanced weekly split—60-70% low-moderate zones, 20-30% high zones—builds endurance without overreaching.
