Note: you will need to take the tour first! I came to this place initially to supplement my kickboxing/weight training and running workouts. Used a Groupon but ended up joining for $399 for 1 year.
I was initially afraid of the "hot room", but it's actually not that bad. Obviously you need to go to a couple classes to get used to the heat but once you do get accustom to it, the workouts are quite satisfying. Hot Pilates, Yoga+Pilates 75X and kettle bells are my personal favorites. I hear good things about the Boot camp and Barre class also. As for instructors, Julie, Eliza, Diana, Cameron, Lisa V., Danielle, and Marie are all great (and hard)!
