Pilates Equipment

The Pilates Reformer is a piece of equipment used in Pilates created by Joseph Pilates and improved by STOTT PILATES professionals. The reformer is unique to other strength training machines in that has spring resistance versus a weight load. As instructors we can use the spring resistance to increase or decrease the challenge in any exercise.

Nucleo Fitness is a fully equipped studio with all the Pilates equipment and the common theme is the spring load to create resistance. No two workout sessions will be the same with the variety of equipment used. For example; we incorporate the Chair, Cadillac, Barrels, and various mat tools in our programing. Our instructors have been trained by STOTT PILATES Instructor Trainers on these various pieces of equipment to give our clients a safe and effective workout each time they train with us.


STOTT PILATES ® is a contemporary approach to the original exercise method pioneered by the late Joseph Pilates. Co-founders Moira and Lindsay G. Merrithew, along with a team of physical therapists, sports medicine and fitness professionals, have spent more than a decade refining the STOTT PILATES method of exercise and equipment. This resulted in the inclusion of modern principles of exercise science and spinal rehabilitation, making it one of the safest and effective methods available. This clear and detailed approach forms the basis for STOTT PILATES training and certification programs. It’s used by rehab and prenatal clients, athletes, celebrities and everyone in between.
