Training mask

A training mask, often called a respirator or elevation mask, is a device worn over the face to restrict airflow during exercise. It simulates high-altitude conditions by limiting how much air you breathe in, which can help improve lung capacity and stamina over time. The mask doesn't just make breathing harder; it creates a training environment similar to being at higher elevations, encouraging your body to adapt and become more efficient. Athletes use it to enhance endurance and respiratory strength, although its actual effectiveness varies and it should be used safely within proper training routines.
