While I don’t disagree with the comment, I tried this for the first time today and I was impressed how effortless it was to use. Everything TR does seems well thought out and just on the mark, like your favorite car. (that’s an old Mad Magazine joke: Cadillac, the Rolls Royce of cars)
At the very low powers I train at, my trainer can’t go any easier, so I can “overdrive” the trainer and run the extended cool down at whatever intensity I want; it’s like it’s not in Erg mode.
