The New Science of Getting in Shape
In fall of 2013, the Vail Vitality Center and the Human Performance Lab at Anschutz Health and Wellness Center in Denver debuted a performance test to the public that had previously only been offered to elite and professional athletes. Developed by Basque doctor Iñigo San Millán, it goes beyond discovering VO2 max (an indicator of your aerobic fitness) and lactate threshold (an indicator of your anaerobic fitness), and does what no other test has done before: It gives you an exact number range for your six heart rate training zones and pinpoints the exact beats per minute (BPM) when you stop burning fat and start burning carbs.
That’s a big deal.
