发明名称 Waist and buttocks exerciser
摘要 A waist and buttocks exerciser has a base, a seat being mounted pivotally on the base, multiple connectors being mounted on the base, a resilient rope being wrapped around the connectors and two leg supporters being attached rotatably onto the base. Each leg supporter has a pin being mounted through the leg supporter and being mounted between and abutting the resilient rope. When a user sits on the seat and places his feet on the leg supporters, the leg supporters can be driven toward different directions. With pins abutting and keeping pushing the resilient rope, user's waist, buttocks and thighs can be exercised.
