I was going to try Martha's at one point, but I didn't follow up for some reason. In general, the price for individual lessons is very high (I used to do it back in the states, though), but I thought I would give Pilateszone a try for a mat class as a colleague recommended it. I was more than pleasantly surprised as I thought mat classes were pretty weak at gyms, etc. Jasmin is very hands-on and well trained in the methods...a bit I actually need to come up to speed with the others. But even after 4 lessons I see a noticeable difference -- it's actually harder than the individual lessons I used to take!
