Of all the places I've worked out, I would say although probably the hardest, I've had the most fun working out at Flywheel. I've only done the cycling classes, but I'm sure FlyBarre would be equally as difficult. Most classes are only 45 minutes long, but you definitely get your workout in. I always leave sore and totally sweaty but with a smile on my face. From the instructors who motivate you through the entire class to the club like music and dark ride, it makes working out dare I say... Fun?
