Patent ID: 10786704

Abstract:
An assisted abdominal sit-up device comprising a foam in a lumbosacral assist block, hip elastic straps, abdominal elastic straps and a hip stability pad. During an extension phase of a sit-up cycle, the hip elastic straps become stretched and stores energy and the abdominal elastic straps keep the lumbosacral assist block in close contact with the user's lower back. When pressure is released from the hip elastic straps during a flexion phase of the sit-up cycle, the stored energy will be released from the hip elastic straps to a user's lower back. When the user's lower back rises up from the floor during the flexion phase, the lumbosacral assist block stays in direct contact with the user's lower back. The hip stability pad adapts to the human pelvis and prevents the assisted abdominal sit-up device from moving along a floor.
