A hamstring exercise apparatus preferably includes a frame provided with a seat section, handle bars, rear axle, rear wheels and swiveling front wheels. The seat section is mounted at a front end of the frame such that the frame is provided with a first opening intermediately disposed between the rear axle and the seat section for receiving user feet therethrough while the user is seated on the seat section and facing the rear end of the frame. Such a frame is further provided with a second opening intermediately disposed between the handle bars. The second opening receives the user feet therethrough while the user is seated on the seat section and facing the front end of the frame. Such first and second openings are advantageously provided for providing room for feet or foot placement and leg movements as the hamstring exercise apparatus is propelled forward during use.

What is claimed as new and what is desired to secure by Letters Patent of the United States is: 1. A hamstring exercise apparatus for strengthening hamstring muscles, said hamstring exercise apparatus comprising: a portable frame adapted to receive and support a user thereon, said frame including a rear axle extending transversely to a longitudinal length of said frame, a seat section mounted at a front end of said frame, and a plurality of handle bars extending upwardly from said front end of said frame and statically engaged to said seat section; a plurality of front swivel wheels coupled to said front end of said frame; and a plurality of rear wheels coupled to said rear axle; wherein said frame is provided with a first opening intermediately disposed between said rear axle and said seat section for receiving user feet therethrough while the user is seated on said seat section and facing said rear end of said frame; wherein said frame is further provided with a second opening intermediately disposed between said handle bars, said second opening for receiving the user feet therethrough while the user is seated on said seat section and facing said front end of said frame; wherein said frame comprises a U-shaped bottom section having a rear end situated distally of said rear axle for providing support to the user feet, said bottom section extending along an entire longitudinal length of said frame and being monolithically formed with said handle bars at said front end of said frame; wherein said bottom section is oriented along a horizontal plane registered above said rear axle and thereby supported by said rear axle. 2. The hamstring exercise apparatus of claim 1, wherein said rear axle has a planar top surface spanning along an entire width of said frame, said top surface being adapted to receive and support the user feet thereon. 3. The hamstring exercise apparatus of claim 2, wherein said seat section comprises: first and second rectilinear legs extending upwardly from said bottom section of said frame; a rectangular platform statically mated to top ends of said legs and said handle bars respectively; and a pad situated on said platform for providing a cushioned surface on which the user sits during operating conditions; wherein said legs are registered orthogonal to said bottom section and located midway along the longitudinal length of said bottom section. 4. The hamstring exercise apparatus of claim 3, wherein said platform is centrally aligned along a width of said frame. 5. The hamstring exercise apparatus of claim 4, wherein said front swivel wheels are freely rotated along a corresponding vertical axis registered orthogonal to said bottom section. 6. The hamstring exercise apparatus of claim 5, wherein said handle bars are forwardly offset from said vertical axes and thereby allow the user to lean forwardly and away from said seat section during exercising procedures. 7. The hamstring exercise apparatus of claim 6, wherein said rear wheels are fixedly aligned along a uniform direction and rotate about an x-axis without swiveling away from said uniform direction as said front swivel wheels rotate about said vertical axes respectively. 8. A hamstring exercise apparatus for strengthening hamstring muscles, said hamstring exercise apparatus comprising: a portable frame adapted to receive and support a user thereon, said frame including a rear axle extending transversely to a longitudinal length of said frame, a seat section mounted at a front end of said frame, and a plurality of coextensively shaped handle bars extending upwardly from said front end of said frame and statically engaged to said seat section; a plurality of coextensively shaped front swivel wheels coupled to said front end of said frame; and a plurality of coextensively shaped rear wheels coupled to said rear axle; wherein said frame is provided with a first opening intermediately disposed between said rear axle and said seat section for receiving user feet therethrough while the user is seated on said seat section and facing said rear end of said frame; wherein said frame is further provided with a second opening intermediately disposed between said handle bars, said second opening for receiving the user feet therethrough while the user is seated on said seat section and facing said front end of said frame; wherein said frame comprises a U-shaped bottom section having a rear end situated distally of said rear axle for providing support to the user feet, said bottom section extending along an entire longitudinal length of said frame and being monolithically formed with said handle bars at said front end of said frame; wherein said bottom section is oriented along a horizontal plane registered above said rear axle and thereby supported by said rear axle. 9. The hamstring exercise apparatus of claim 8, wherein said rear axle has a planar top surface spanning along an entire width of said frame, said top surface being adapted to receive and support the user feet thereon. 10. The hamstring exercise apparatus of claim 9, wherein said seat section comprises: first and second rectilinear legs extending upwardly from said bottom section of said frame; a rectangular platform statically mated to top ends of said legs and said handle bars respectively; and a pad situated on said platform for providing a cushioned surface on which the user sits during operating conditions; wherein said legs are registered orthogonal to said bottom section and located midway along the longitudinal length of said bottom section. 11. The hamstring exercise apparatus of claim 10, wherein said platform is centrally aligned along a width of said frame. 12. The hamstring exercise apparatus of claim 11, wherein said front swivel wheels are freely rotated along a corresponding vertical axis registered orthogonal to said bottom section. 13. The hamstring exercise apparatus of claim 12, wherein said handle bars are forwardly offset from said vertical axes and thereby allow the user to lean forwardly and away from said seat section during exercising procedures. 14. The hamstring exercise apparatus of claim 13, wherein said rear wheels are fixedly aligned along a uniform direction and rotate about an x-axis without swiveling away from said uniform direction as said front swivel wheels rotate about said vertical axes respectively.
