About Ben Greenfield

Ben Greenfield is a human performance consultant, speaker, and New York Times bestselling author of 18 books including Boundless and Beyond Training. A 13-time Ironman triathlete and former collegiate multi-sport athlete, he was voted America's top Personal Trainer by the NSCA and named one of the top 100 Most Influential People in Health and Fitness. His Ben Greenfield Life podcast consistently ranks among the top health shows in the world with millions of downloads.

Greenfield first discovered Vasper in 2012 - before it was commercially available. Years later he installed a unit in his home gym in Spokane, Washington, ran a personal 40+ session experiment over 3 months, then interviewed Vasper co-founder Sebastian Wasowski on his podcast. He lists Vasper as a permanent recommendation on his site and uses it every morning as part of his daily protocol.

Why this Matters

Ben Greenfield has tested hundreds of devices and interventions over 20+ years. Unconditional superlatives from him are rare - he calls Vasper "bar none" the best exercise machine he has ever used, a statement that carries real weight in the biohacking community. His audience actively follows his protocol-level recommendations. His permanent product recommendation page on bengreenfieldlife.com drives ongoing organic discovery month after month.
