Open the CIPO recordAbstract From the Canadian patent
An apparatus for isolating the abdominal muscles and effectively loading them during exercise is disclosed. The device supports the user's body in a position which allows for trunk flexion; however, it forces the user's knee flexor and hip extensor muscles to contract, relaxing the hip flexor muscle, and isolating the abdominal muscles. Consequently the only muscles exercised during the trunk flexion are the abdominal muscles.

Why it's free to use
- Filed July 6, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
