I started in mid november at 88kg and managed to get down to 81kg (179lbs), but because of christmas I went back up to 85kg.
When finding this out I decided to go superman on my training (cardio) and am now back down to 83kg. My goal is 75kg.
So far it has been beneficial to my knees and movement! I was fast already but it was much more wear and tear style of running. Not as tired as well
