20 Group Reformer lessons. This is for 20 group reformer lessons, expires within 6 months. Please NOTE: To join group reformer at KORE, you must do a mandatory private with one of our reformer teachers, since we teach Classical Pilates, which is not offered at many studios. The technique, mechanics, breath, and formula are in depth. This is for YOUR benefit. We don't want our clients to feel lost during group classes, which is why we require this first. Please respect our policy.
