How to Improve Your VO2 Max: A Data-Driven Guide

VO2 max is the maximum amount of oxygen your body can take in, transport and use per minute. Watch estimates can be 10-15% off; a laboratory test with breath-by-breath gas analysis gives the real value plus ventilatory thresholds VT1 and VT2. Build an aerobic base, add 4-6 x 3-5 minute intervals at 90-95% of max heart rate, keep threshold work and recover deliberately for 10-20% gains in 8-12 weeks.
