10 repeatable functional tests — heart rate recovery, grip strength, chair stand, balance, VO2 max and more — with a baseline/retest tracker.
Where oxygen recovery fits in
Recovery tools support consistency — they do not replace training, sleep, or nutrition. If passive recovery belongs in your routine, see the research behind Bimini oxygen nanobubble immersion, including the Rice Sports Medicine pilot white paper.
Studied at Rice University. Bimini systems are wellness devices, not medical devices, and are not intended to diagnose, treat, cure, or prevent any disease.
