I’ve been attending Yalckun’s mat pilates classes since September 2015, and I can’t recommend them highly enough. Yalckun is an incredibly thoughtful, detailed, and thorough teacher, and his classes are always interesting, challenging, and fun. The strength and fitness I’ve gained from the class has been remarkable—it’s as close as my 45-year-old self is going to get to the fountain of youth. Like many other people, I spend an awful lot of time sitting at a computer for my work, and the mat pilates classes have been essential for me in both healing and preventing all the aches and pains that can go along with such work. Yalckun is a knowledgeable, kind, and patient teacher, and works well with a wide range of ages and fitness levels. His goal when teaching class is to improve everyone’s strength, from whatever fitness level they are at—so he will modify exercises where necessary. Yalckun is also adamant about maintaining safety for everyone’s back and joints. So (unlike some exercise classes I’ve taken at regular membership gyms), no matter how challenged I feel by Yalckun’s pilates class, I don’t fear being injured. I know the techniques Yalckun is teaching are safe, and that I won’t be pushed beyond what I am capable of doing. If you are considering pilates, I urge you to give Yalckun’s mat class a try.
