IHT Factor Training in downtown San Diego delivers intermittent hypoxic training from its Sixth Avenue altitude lab, simulating elevations up to 13,000 feet to trigger oxygen-efficiency adaptations during HIIT and strength circuits. The altitude chamber forces the body to increase red-blood-cell production and improve VO2-max under reduced-oxygen conditions, a nervous-system adaptation protocol that stacks with the hyperbaric and shockwave recovery modalities at Swell Chiropractic in Bankers Hill. Post-session recovery rotates through cold plunge, infrared sauna, and contrast therapy, cycling members between thermal extremes to accelerate lactic-acid clearance and reduce delayed-onset muscle soreness. Active-duty military members receive a standing rate reduction, and the facility runs dedicated boxing, core-training, and body-conditioning classes outside the altitude chamber for members who want to train at sea level. The full-spectrum recovery protocol—altitude stress followed by thermal contrast—builds a physiological rebound cycle that parallels the assisted-stretch and mobility programming at Stretch & Recovery Room. The most advanced programming layers altitude-exposure intervals with boxing conditioning and heart-rate-zone tracking, building sport-specific aerobic capacity for competitive endurance athletes and tactical professionals.
