The Wunda Chair is the reformer's short, upright cousin: the same springs, worked sitting and standing, and much harder than it looks. Classes are four people at most, on four chairs, so the instructor watches all of you and corrects each of you.

At most 4, because that is how many pieces of equipment the studio has. Nobody is at the back of a room.
No. Every exercise is set for the person doing it, and a first class is spent teaching you the machine rather than pushing you on it.
A single class is KES 2,500, and packs bring that down. Prices are on the pricing page, and what you see is what you pay.
60 minutes.
