A muscle strengthening apparatus comprising a substantially arch-shaped member having a first end and a second end, the arched-shaped member having a predetermined degree of resiliency, an ankle contact member having a pair of ankle contact portions for contacting the ankles of a user, the ankle contact member being attached to the arch-shaped member adjacent to the first end, and a buttocks contact member for contacting the buttocks of the user, the buttocks contact member being attached to the arch-shaped member adjacent the second end.

Apparatus for stimulating hamstring contraction to effect optimum abdominal muscle conditioning

A muscle strengthening apparatus comprising a first elongate member, a second elongate member, a feet securing member and a support member. The first and second elongate members have a pair of end portions. The feet securing member secures the feet of a user and is attached to an end of the first elongate member. The other end of the first elongate member has an engagement portion. The second elongate member is slidably engaged with the first elongate member. The axes of the first and second elongate members are substantially coaxial and the movement of the first and second elongate members is substantially linear. The apparatus further comprises a system for exerting a force on the first and second elongate members so as to urge the first and second elongate members in opposite directions. The support member is configured to contact the buttocks of the user and is attached to the other end of the second elongate portion. The apparatus further includes a spring disposed within the first and second elongate members wherein the spring urges the second elongate member in a direction away from the feet securing member.

Linear motion apparatus for stimulating hamstring contraction to effect

A muscle strengthening apparatus comprising a feet securing member for securing the feet of a user, a support member for contacting the buttocks of the user, and a resilient member attached between the feet securing member and the support member. The resilient member comprises a first portion and a second portion wherein the first and second portions are angulated with respect to each other. The first and second portions each have an end opposite the point of contiguity of the first and second portions. The feet securing member is attached to the end of the first portion. The support member is attached to the end of the second portion. When the user's feet are secured by the feet securing member and the user's buttocks contacts the buttocks support member, the first and second portions of the resilient member are positioned generally posteriorly and/or medially with respect to the legs of the user.
