Donner is 3x12-minute Threshold repeats which undulate between 95-99% FTP and 6-minute recoveries separate the intervals.
Donner's primary aim is to increase higher-muscular endurance, also referred to as strength endurance.
Over time, the ability to work harder without accumulating high levels of blood-lactate and muscle fatigue will improve.
These intended adaptations yield less muscle burn, higher sustainable power and an improved ability to tolerate and process excess lactate.
