Hi all!!! I'm 52 years old and determined to get fit, I lost almost 2 st over the course of last year, had a hysterectomy 4 months ago and now I feel fab for the first time in quite a few years. So after doing week 1, I was raring to go on WK 2!!!! 90 seconds feels like an eternity at the moment, am praying it gets easier on run 2 tomorrow Lol!!!!
