Tom Butler completed his 4th VO2 max test after training fifteen minutes a day for 11 weeks. His results show relative VO2 Max and METs increases of over 28%.
Experts say the maximum gains for VO2 Max is 15-20%. Tom achieved this in under 20 hours of actual training with LiveO2™. Tom used LiveO2 Adaptive Contrast which limited his hypoxic intervals to about 10,000 feet of simulated altitude.
LiveO2 – Extreme provides adjustable hypoxia to about 25K feet of simulated altitude and is better suited to VO2 Max and Lactic threshold training methods.
