We also provide the Heart Rate Reserve using Coggan's zones, a highly regarded methodology in sports science.

For the more seasoned athletes, we propose the Lactate Threshold Heart Rate (LTHR) method, which accounts for the stage at which lactic acid starts to build up in the bloodstream; Joel Friel's approach, tailored specifically for cyclists and triathletes; and the British Cycling method, a commonly used strategy in professional cycling.
