Yemi runs the new F45 studio in Brixton. If you're not sure what F45 is, think an Australian version of CrossFit with the mentality of Soul Cycle. It's "community meets technology," Yemi explains. You work out with other people and with plenty of different exercises in play, you never get the same workout twice. Most importantly though, it's fun. "In my first class I was laughing as I was working out, even though I was struggling to breathe," remembers Yemi. "There were exercises that I’ve never done before, so I had aches that I never thought that I could have because the moves were so dynamic. And doing it with a friend made it more enjoyable."
