NFL George Kittle Details Vasper Training Boosting Testosterone, Recovery

San Francisco 49ers tight end George Kittle has openly discussed his use of the Vasper machine, a recovery bike that combines blood flow restriction, compression, cooling, and interval training to enhance recovery and boost testosterone levels. Kittle revealed on the "Bussin with the Boys" podcast that he incorporates the Vasper machine into his routine four days a week during summer training, noting that it improves his sleep quality and has a surprising positive effect on his sex life, specifically increasing testosterone and sexual performance. Initially skeptical, Kittle acknowledged how the machine was promoted among NFL players for these benefits, with some coaches also regularly using it. The technology tricks the brain into thinking the body has undergone intense exercise, stimulating recovery and muscle growth without the physical wear and tear of typical training. Kittle, who invests significantly to maintain his peak condition, is optimistic about his NFL future and expects to play until it no longer remains enjoyable. His candid comments have sparked interest in this unconventional training method's impact both on athletic performance and personal well-being.
