I love OTF! I love the workout. I love your location but would go to this location more if the treadmills were different. I really would love love love if you switched out the treadmills so they are the same as the ones at Colonnade, PV, Scottsdale Ranch.
The coaching and having a coach directing the class to maximize each individual participants workout. That's not easy to do. Also, even though it might be the coaches 3rd or 4th session he/she makes you feel likes it's his 1st session of the day. That's not easy to do either.
