Calvin, Paige and Amy are great trainers! I've had Chantelle once and liked her too. Trainers make or break the experience. Their energy, attention to detail, music, motivation - it all makes for the best workout experience!
This style of workout is very effective for me. Circuit training proved very beneficial to building muscle and increasing stamina. The instructors are all knowledgeable and very nice; the have each client's best interest in mind. The facility is very clean and organized. The front staff is professional, helpful, and kind, too.
My only hangup was the loud music, but that was a personal preference. Maybe 3/4 as loud?
Just a bit of feedback... in every other city that I've done OTF, you stay w/ the same # station for treadmill, rower AND floor. It makes for very smooth, quick transitions. I've been to your OTF multiple times and it's always a free for all of people scrambling to get a station on the floor, one time two women were using weights from my station and it wasn't even s full class. I think it would be great if you also implemented this process. Isn't that why everything is numbered?
