She's President of the "Ratchet Mom Club," a dynamite Peloton tread instructor, and proud mama of two. Yes, the inspiring Kirsten Ferguson is joining Maria today. Despite her enormous success after just one year at Peloton, she reveals that she wasn't always a big fitness girl. Kirsten shares how fitness found her at the right time and the moment she recognized it was her calling. She also gets vulnerable with her road to motherhood -- the highs, the lows, and everything in between. Both her fitness and motherhood journeys have taught her some valuable lessons that she shares with us today. And, we learn her go-to song and cocktail right now!
