Gliders were inspired to mimic the Pilates Reformer moving carriage - except lightweight, handbag-size, and travel-friendly. Dual-sided means you can slide on both carpet and hard floors. Benefits go far beyond the convenience factor - they layer a whole new dimension to your workout and will take body sculpting, balance, and cardio to the next level. They are a low-impact (joint-friendly) solution to building strength, endurance, flexibility, and coordination. Save the stress for something other than your joints.
