THIS IS A MISTAKE. Mona Fartlek has been around for years and was a regular workout in Steve Moneghetti’s programme. Whilst Warming Up this morning to do a Mona Fartlek session I did an Instragram Story and described the workout incorrectly, this workout here is the result, which I’ve called Mona Fartlek Plus….because it is a little bit more than a Mona Fartlek.
