VASPER
NASA-derived liquid cooling. Blood flow restriction compression. Precision interval training. In 21 minutes, Vasper triggers the anabolic hormone cascade of a 2-hour high-intensity workout — without the damage, fatigue, or recovery time.

Maximum Signal.
Vasper is a patented fitness and rehabilitation technology that combines three scientifically validated principles: liquid cooling, compression, and interval training. Originally developed using NASA liquid cooling garment technology, Vasper creates the physiological response of an intense 2-hour workout in just 21 minutes — at any fitness level.
During exercise, your body normally shunts blood away from working muscles to cool the skin — reducing oxygen delivery and accelerating fatigue. Vasper's liquid cooling keeps your core temperature low, keeping oxygen-rich blood in the muscles throughout. Simultaneously, compression cuffs rapidly accumulate lactic acid, sending a powerful anabolic signal that triggers a cascade of growth hormone and testosterone release.
The Science
Behind It
Each pillar is independently validated. Together their synergy creates the Vasper effect — an anabolic hormonal response your body can't achieve any other way in 21 minutes.
Originally developed for NASA astronaut spacesuits, liquid cooling circulates cold water through compression cuffs on your arms, legs, and a cooling vest. This prevents blood from being shunted to the skin surface during exercise — keeping oxygen-rich blood inside the working muscles throughout the entire session. The result: dramatically higher exercise efficiency, near-zero sweating, and no post-workout soreness.
Compression cuffs on all four limbs safely restrict venous return during exercise at low intensity — rapidly accumulating lactic acid in the muscles. This metabolite buildup mimics the physiological signal of an intense, exhausting workout, triggering the body's systemic recovery response: a massive release of Human Growth Hormone and testosterone. Compression activates fast-twitch muscle fibers and drives the anabolic cascade without any high-load joint stress.
Each 21-minute Vasper session follows a precisely calibrated interval protocol — warm-up, alternating sprint and recovery intervals, customized to your chosen intensity level. The interval structure maximizes the anabolic hormonal response, enhances mitochondrial biogenesis, and drives cardiovascular conditioning. All metrics — heart rate, power output, session data — are tracked on a fully integrated tablet and can be emailed post-session.
4 Levels of Intensity
Every Vasper session is customized. Our team selects the right protocol based on your goals, fitness level, and health status before every session.
Gentle introduction to compression and cooling at minimal intensity. Ideal for your first session, those new to exercise, or anyone who wants to understand the Vasper experience before progressing. You'll still trigger the hormonal response — just at a comfortable, manageable level.
Designed for individuals recovering from injury, surgery, or managing chronic pain conditions. The low-impact NuStep platform eliminates joint stress while compression and cooling still drive the anabolic hormone response, accelerating tissue repair and reducing inflammation without exacerbating existing damage.
The most popular protocol for active adults and longevity seekers. Delivers the full Vasper effect — significant GH release, elevated testosterone, mitochondrial enhancement, improved sleep — in 21 minutes. This is where most clients spend the majority of their sessions once acclimated.
Maximum compression, maximum interval intensity — calibrated for competitive athletes, professional sports players, and those seeking peak endurance and power output. Drives the most significant hormonal, cardiovascular, and metabolic response. Used by Olympic athletes, NHL players, and elite endurance competitors.
Born From
Space Science
Vasper was founded in 2009 by Peter Wasowski after integrating NASA's liquid cooling garment technology with blood flow restriction research. It is currently used by Olympic athletes, professional sports teams, rehabilitation centers, longevity clinics, and veterans facilities across the US.

Vasper is contraindicated for individuals with Deep Vein Thrombosis (DVT), active blood clotting disorders, or open wounds. The compression cuffs apply significant pressure to the limbs — which could be dangerous if clots are present. Always disclose any history of blood clots or clotting disorders before your first session.
Vasper is not recommended during pregnancy. The combination of compression, cooling, and elevated exercise intensity creates physiological changes that are not appropriate during pregnancy. If you are pregnant or may be pregnant, please consult your healthcare provider before participating in any exercise program at Longevity Gyms.
You are barefoot during Vasper sessions because the soles of your feet are one of the body's most effective heat exchange surfaces. Cooling your feet throughout the session helps regulate your core temperature and maximizes exercise efficiency. Bring comfortable socks to wear before and after your session if desired.
A cardiovascular safety study of 20 healthy participants across 7 sessions with varying compression pressures found no significant differences in heart rate or blood pressure — confirming Vasper's safety across the full allowed pressure range. Our team reviews your health history before every first session and monitors all clients throughout their workout.
The Research
Behind It
Vasper is built on three independently validated scientific principles. The research spans direct Vasper studies, NASA technology documentation, and the broader blood flow restriction and cooling literature.
Direct Vasper study documenting that exercise with Vasper's cooling and BFR system mobilizes CD34+ hematopoietic progenitor cells and platelets to peripheral circulation — with potential applications for vascular repair, angiogenesis, and orthopedic recovery enhancement. Jagiellonian University researchers linked this finding to endothelial repair and blood vessel regeneration.

Documents the NASA origin story, the technology transfer, and early clinical applications including use by Olympic athletes and professional sports players.
Read Full Article→Pilot trial at the Warrior Evolved Veterans Rehabilitation Facility (Colorado Springs) documenting significant sleep improvements in 71% of US armed forces veterans after 24 Vasper sessions over 6 weeks — measured by the Pittsburgh Sleep Quality Index (PSQI). Also documented improvements in energy and fatigue scores on the SF-36 quality of life questionnaire, suggesting broad wellness benefits beyond physical performance.
Read Research→Research documenting that combining blood flow restriction (BFR) compression with high-intensity interval exercise produces Growth Hormone release exceeding 2000% above baseline — far surpassing conventional resistance training. This is the core physiological mechanism behind Vasper's anabolic effect: lactic acid accumulation from BFR compression sends the maximum possible GH release signal to the pituitary gland in just 21 minutes.
View Journal→Vasper study of 5 professional baseball players over 8 sessions (2 weeks) found 80% showed increases in free testosterone levels, with an average increase of 132% across all participants. Testosterone is critical for muscle growth, bone density, fat metabolism, mood regulation, and competitive performance — making this finding particularly significant for both athletic performance and longevity applications.
Read Research→2021 meta-analysis confirming that low-load resistance training combined with blood flow restriction (BFR) produces gains in muscle strength and mass comparable to high-load conventional resistance training — without the joint stress, muscle damage, or recovery time. This is the scientific foundation for Vasper's ability to build strength at any fitness level, including rehabilitation patients and elderly individuals who cannot tolerate heavy loads.
