Add all the benefits of cardiovascular fitness to your AeroPilates workout with the AeroPilates with Free-Form Cardio Rebounder. In fact, with the AeroPilates reformer, you will reach and maintain your target heart rate as effectively as with a treadmill. But unlike the treadmill, the AeroPilates Free-Form Rebounder is low impact and gentle on your joints, and since you are lying on your back, there is no concussion on your legs, hips, or spine. Some Pilates machines feature a padded jumpboard made of solid wood, but the AeroPilates Free-Form Rebounder is like jumping on a trampoline. So, there is more give and less shock to your joints. Plus, the AeroPilates strength and flexibility training gives you the strong, streamlined, flexible body that only Pilates can achieve. Assembled dimensions: 85" long x 20" wide x 27" high. The cushion assembly is 21.5" wide, and the stand is 12" tall, so the 27" height is measured from the floor to the top of the Free-Form Cardio Rebounder when the unit is on the stand.
