This Class FitSugar workout led by AFAA- and ACE-certified trainer Nicole Steen is a go-to sweat session for Yerin Kim, associate editor of trending and viral features at POPSUGAR. "Nicole explains every move so clearly and the modifications are great, so it was the perfect workout for me to dip my toes into getting used to exercising at home at the start of quarantine. Now, it's a part of my weekly rotation, and it's easily adjustable to make more challenging with advanced moves and added weights. As an added bonus, I just love Nicole's energy and positive vibe!"
