Started going to their Sunday Karma classes because I wanted a drop-in yoga that was cheap, and it was an awesome perk knowing that the money goes to a good cause each class! The room is almost always close to full, but never uncomfortably so. The karma yoga varies in difficulty each time, but tends to be on the tougher side. The class is a whole hour and 30 minutes! It's a hot yoga, but not over the top with heat. The instructor covers sun salutations, strength poses, balances, and abs as well as a longgg shavasana and a chilled lavender soaked towel at the end. Heavenly after some tough yoga!
