Martial Posture is a great place for karate instruction. There is a wide range of students here, from little teeny white belts as young as 4 all the way up to big tall black belts, and everything in between. Located at 21st and Chestnut, this is a convenient location for Center City residents — close to parking, mass transit and many restaurants. Classes are held for each level on Saturdays and two days during the week(some M&W, others T&Th). For $ 99 you get eight lessons a month, which you can take whichever days you want. This flexibility has been very helpful. What really sets this school apart to me though is the excellent teaching staff. Mr. Ish leads the school and he’s a great leader to both the students and his staff. Discipline is maintained, but never in a mean way, always with kindness or humor. Black belt students help with classes and often assist students who need extra help. Classes are small or split up into smaller groups, and each starts with a very good warmup followed by instruction which concentrates on a series of moves; teachers also show the students how the moves apply to actual combat. In addition to classes there is a sparring class for all ages. There is also a room for students before or after class where they can read, watch a movie or play computer games, do their homework or just hang out. There’s a water dispenser. The classes are supplemented by summer camp weeks and there are after school programs and camps that often coincide with school holidays. I can’t speak highly enough of this great school and the terrific job they do here.
