Overview
An 11 inch diameter, 3 inch high balance disc built for pelvic floor and deep core activation, supporting up to 264 lbs and including a non-slip base plus an exercise manual.
The design targets a narrower use case than a general balance trainer, pelvic tilts, pelvic clock exercises, and postpartum or pelvic floor rehabilitation work, though it also scales up to more demanding Pilates movements like V-sits and toe taps for users who progress past the basics. OPTP frames it as a starting point for pelvic floor and core stability work rather than a general fitness balance board, and recommends checking with a physician before beginning a pelvic strengthening program.
- 11 inch diameter, 3 inch high exercise platform
- Supports up to 264 lbs
- Includes a manual with pelvic tilt and pelvic clock exercises
- Non-slip base included for extra traction
Who it's for
Suited to people beginning pelvic floor rehabilitation, postpartum core recovery, or SI joint support work under guidance from a physical therapist or physician. Not intended as a general purpose balance trainer for athletic training or plyometric work.
Pros and cons
- Soft rubber edge cushions seated and supine exercises
- Non-slip base adds grip on slippery floors
- Supports up to 264 lbs
- Comes with an exercise manual to guide the pelvic floor program
- Narrow focus on pelvic floor and core work, not a general balance trainer
Performance notes
The 11 inch platform and 3 inch height create instability aimed at activating the transverse abdominis and pelvic floor muscles during seated or supine movements like pelvic tilts and pelvic clocks. The soft rubber edge cushions contact points during floor work, and the separate non-slip base adds grip on surfaces that would otherwise let the disc slide. Progression from basic tilts to Pilates moves like V-sits depends on core strength built up over the included program, not the disc itself.
