SEP, the Safe Energy Production, shows the momentary maximal energy generation that the aerobic system is capable of with aerobic domination.
You get real-time SEP data from mnsX during training (red graph). SEP value is relative, and its range is 0-100%. The effort that belongs to 100% is changing from training to training. It is based on your daily form.
SEP's value and gradient contain a lot of different types of information, which depends on the section of training (warmup, high-intensity, regeneration phase, or cooldown).
SEP is the key to complete control over your training.
