An exercise machine is provided having a platform on which a user is supported in a reclining position with the weight of the user being utilized as a resistance which may be selectively varied to the various exercises which may be performed on the exercise apparatus. A lever is pivotally connected to the platform with the lever being actuated by the user for raising one end of the platform with respect to a pivot point with resistance to such raising being varied by the pivotal mounting of the lever on the platform. Two of the various embodiments include a base support having a rail on which a lever has a roller mounted for riding movement thereon and pivotally connected to a lower leg for pivotal movement. Other embodiments include a lever having telescoping members with an inner one of such telescoping member being selectively fixed to a rail. Such inner telescoping member reciprocates within an outer telescoping member as the platform is raised and lowered.
An exercise machine adapted for placement on a supporting surface and adapted for using the body weight of the user as a resistance to exercise which may be selectively varied, said exercise machine comprising:
An exercise machine for supporting a user in a reclining position thereon and using the body weight of the user as a resistance to exercise which may be selectively varied, said exercise machine comprising:
An exercise machine for supporting a user in a reclining position thereon and using the body weight of the user as a resistance to exercise which may be selectively varied, said exercise machine comprising;
