CellAir
Intermittent Hypoxic Training Device from Cellgym. Designed to simulate the effects of high-altitude training, Cellair helps improve oxygen efficiency, boost stamina, and support recovery by alternating between periods of low and normal oxygen levels.

CellAir is a cutting-edge device from Cellgym that harnesses the power of intermittent hypoxic training (IHT) to enhance overall health, fitness, and performance.
What is CellAir
Training at altitude, indoors.
This innovative technology is especially beneficial for individuals seeking to improve their physical conditioning, manage stress, or support cellular regeneration. At Dr Jinah Yoo Clinic, we use the Cellair IHT device to help our clients optimise their wellness and fitness goals, improve recovery times, and achieve enhanced mental and physical resilience.
How CellAir works
Low oxygen, then normal.
The Cellair device utilises intermittent hypoxic training, which involves brief exposure to low oxygen levels (hypoxia) followed by periods of normal oxygen levels (normoxia). This process simulates the conditions of high-altitude environments, encouraging the body to adapt to reduced oxygen availability. As the body adapts, it improves oxygen delivery to tissues, which helps boost endurance, increase energy levels, and promote overall wellness.
