DETAILED DESCRIPTION

(11) Referring to FIGS. 1 through 10, wherein like reference numerals refer to like components in the various views, there is illustrated therein some implementations of an exercise device.

(12) FIG. 1 is an isometric view of one implementation of a first block 12 of an exercise device. First block 12 may be in the form of a modified rectangular prism (e.g., approximately 8 inches high by 24 inches long by 17 inches wide) having a top 14, bottom 16, front 18, back 20, right side 22, and left side 24. The left side 24 of the first block 12 may have a pair of cutouts such as D-shaped cutouts 26 extending downwardly from the top of the block (e.g., approximately 4.5 inches wide by 4-6 inches deep, with a medial portion extending inwardly into the block approximately 6.75 inches to accommodate a user's feet) for some exercises, or a user's elbows for other exercises. The right side 22 may have a single cutout such as D-shaped cutout 28 extending downwardly from the top of the block (e.g., approximately 4.5 inches wide by 4 inches deep, with a medial portion extending inwardly into the block approximately 6.75 inches to accommodate a user's foot) for some exercises.

(13) FIG. 2 is a left side view of a first block 12. A portion 30 of the front side 18 may slope inwardly toward the bottom 16 of the block (e.g., approximately 24 degrees inward angle). A portion 32 of the top 14 of the block may slope inwardly toward the front side 18 (e.g., approximately 12 degrees inward angle).

(14) FIG. 3 is a top view of a first block 12, and FIG. 4 is a front view thereof. At the junction of the top 14 and front side 18, a rectangular notch 34 may be provided for cradling a user's upper arm for some exercises, or a user's lower leg for other exercises.

(15) FIG. 5 is an isometric view of one implementation of a second block 40 of an exercise device. Second block 40 may be in the form of a rectangular prism (e.g., approximately 8 inches high by 8 inches long by 17 inches wide), and may be joined to the first block 12 for use in some exercises, or separated from the first block for use in other exercises.

(16) FIG. 6 is an isometric view of one implementation of a third block 50 of an exercise device. Third block 50 may be in the form of a truncated triangular prism or wedge (e.g., approximately 8 inches high by 3.5 inches long by 17 inches wide, with an approximately 79 degree included angle), and may be positioned between the first block 12 and the ground to tilt and/or stabilize the first block during some exercises.

(17) In some implementations, one or more sides of some of the blocks may incorporate a surface feature to enable the blocks to interlock or otherwise be joined with each other. For example, a trapezoidal tongue 60 on the back side of first block 12 (FIGS. 1 and 2) may slidingly engage with a trapezoidal groove 62 on a front side of second block 40 (FIG. 5). Similarly, a trapezoidal tongue 64 on a back side of second block 40 (FIG. 5) may slidingly engage with a trapezoidal groove 66 on a front side of third block 50 (FIG. 6). In some implementations, the back side 20 of the first block 12, two opposite sides of the second block 40, and one side of the third block 50 may include one of a trapezoidal tongue or corresponding trapezoidal groove to enable all three blocks to be joined together.

(18) These tongue and groove positions can be reversed or exchanged on the respective blocks, or other interlock or joining features to join the blocks could be utilized, as is well known in the art.

(19) FIG. 7 is an isometric view of a first block 12, second block 40, and third block 50 of an exercise device having been partially interlocked together by the trapezoidal tongues and corresponding trapezoidal grooves surface features described above, while FIG. 8 is an isometric view of a first block 12, second block 40, and third block 50 of an exercise device having been fully interlocked together.

(20) FIG. 9 is an isometric view of another implementation of a first, second, and third block of an exercise device, illustrating an alternate surface feature to enable the blocks to interlock or otherwise be joined with each other. First block 70 may include one or more offset posts 72 on a back side thereof, to engage complementary inset sockets 74 on a front surface of second block 76. Similarly, second block 76 may include one or more offset posts 78 on a back side thereof, to engage complementary inset sockets 80 on a front surface of third block 82. In some implementations, the back side of the first block 70, two opposite sides of the second block 76, and one side of the third block 82 may include one or more of an offset post or corresponding inset socket to enable all three blocks to be joined together.

(21) These offset post and inset socket positions can be reversed or exchanged on the respective blocks, or other interlock or joining features to join the blocks could be utilized, as is well known in the art.

(22) In some implementations, the blocks may be used separately or arranged together for a variety of exercises, for example:

(23) Using the first block with the third block underneath will make an incline. Using the blocks this way will allow the user to do the following exercises: incline bench press, incline fly, hyper extension, tricep extension, dumbbell curls, hyperextension, sidekicks for legs, lunges, stretch, decline press, and decline fly.

(24) Using all three blocks with the first block face down, place the small end of the third block under the angle edge of the first block to make a flat surface. Place the second block on the opposite side of the first block to lengthen. Exercises: bench press, dumbbell fly, pullover, nose breakers, and aerobic step.

(25) The blocks may also be used separately or arranged together for a variety of other exercises including but not limited to stretching calves, runners stretch exercise, double standing calf raise exercise, donkey calf raise exercise, seated calf raise exercise, single calf raise exercise, thigh stretch exercise, lunge exercise, aerobic step exercise, side leg raise exercise, single leg squat exercise, hamstring curl with dumbbell exercise, hamstring stretch exercise, hyperextension exercise, stiff leg deadlift/bent over row exercise, donkey kick exercise, bent over row exercise, pullover exercise, bench press exercise, incline bicep curl exercise, dumbbell row exercise, shoulder press, dumbbell side laterals, front laterals, bicep curls exercise, ab stretch/push-ups exercise, decline press exercise, decline fly exercise, e-z curl tricep extension exercise, dips exercise, concentration curl exercise, preacher curl exercise, forearm wrist curl exercise, runners bicep curl exercise, standing preacher curl exercise, lower ab leg raise exercise, sit-up/lower ab exercise, sit-up exercise, and oblique exercise.

(26) The blocks may be constructed from any suitable or appropriate material. In some implementations, the blocks are constructed of polyurethane foam. In some implementations, the blocks are constructed of polyethylene. In some implementations, the blocks are constructed of polypropylene. In some implementations, the blocks are constructed of nylon. In some implementations, the blocks are constructed of inflatable rubber. Other materials may also be used, and the blocks may also be covered, such as by fabric or plastic, for example.

(27) The blocks may be produced by any suitable or appropriate technique. In some implementations, the blocks are produced by roto molding. In some implementations, the blocks are produced by blow molding. In some implementations, the blocks are produced by machining.

(28) In some implementations, the blocks may be contained and carried in a folded mat. In some implementations, the blocks may be part of a core block kit with three blocks, a carrying strap, and a mat.

(29) FIG. 10 is a partially cutaway isometric view of one implementation of a separate block 90 that may be used for core and lower back exercises. Block 90 may be generally rectangular in plan view and with an arcuate cross section (e.g., approximately 6 inches thick at the center by 28 inches long by 18 inches wide), and may include one or a pair of cavities 92, which may be used as a hand grip when doing leg raises. For a sit-up or crunches the user would sit at the end of the block and rock back and forth. When doing leg raises the user would turn the block over to where the arc part would be face down to the floor, and the user would sit in the center of the block and hold on to the cavity hand grips and lean back and do a leg raise. To stretch the stomach the user could lean back on the arc looking at ceiling and have a nice stretch. Also, with the arc facing down to the floor the user could lay face down with their stomach on the arc and do lower back “hyper extensions.”
