DETAILED DESCRIPTION OF THE PRESENT INVENTION [0019] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0020] Reference is now made to Figs. 1 and 2 which illustrate an exercise device 10 according to some embodiments of the present invention. Exercise device 10 may comprise a first foam layer 12 and a second foam layer 14. First foam layer 12 and second foam layer 14 may be attached to each other so that a side of first foam layer 12 defined by the two longest dimensions of first foam layer 12 is attached to a side of second foam layer 14 defined by the two longest dimensions of second foam layer 14.

[0021] According to some embodiments, first foam layer 12 may be affixed to second foam layer 14 in a detachable form, such as by means of hook and loop fastener 15 (e.g., Velcro®) so that the hooks side of fastener 15 is attached to a first side of one foam layer 12 or 14 and the loops side of fastener 15 is attached to a second side of the other foam layer 12 or 14 so that when layer 12 and layer 14 are attached to each other, the hooks side of fastener 15 and the loops side of fastener 15 should be facing each other.

[0022] It should be appreciated that other detachable affixing means may be used such as buttons, zippers and any other detachable affixing means known in the art.

[0023] According to some embodiments of the present invention, first foam layer 12 may be affixed to second foam layer 14 in a non-detachable manner, such as by means of adhesives.

[0024] First foam layer 12 may have a thickness of between 10% and 35% of the entire thickness of exercise device 10, and may have a Shore 00 value of between 60 and 85; and a compression deflection at 25% in the range of 100 kiloPascal (kPa) and 145 kPa.

[0025] First foam layer 12 may be made of a polyethylene foam block, such as Palziv Palfoam

PB65, having a density of 65Kg/m ³ , compression deflection at 25% of 132kPa and a Shore 00 value of 70. It should be appreciated that other foamed polymers may be used.

[0026] According to some embodiments, second foam layer 14 may be softer than first foam layer

12. Second foam layer 14 may have a thickness of between 65% and 90% of the entire thickness of exercise device 10. Second foam layer 14 may have a Shore 00 value of between 30 and 65; and a compression deflection at 25% in the range of 20kPa and 75kPa.

[0027] Second foam layer 14 may be made of polyethylene foam block, such as Palziv Palfoam PA30 having a density of 30Kg/m ³ , compression deflection at 25% of 62kPa and a Shore 00 value of 54. It should be appreciated by those skilled in the art that other foamed polymers may be used. [0028] According to some embodiments, in order to ensure that first layer 12 is harder than second foam layer 14, a minimum difference between the shore 00 values of first layer 12 and second layer 14 may be set. For example, first foam layer 12 may have a Shore 00 value that is 15 points higher than the Shore 00 value of second foam layer 14, on the shore 00 scale. According to other embodiments, first foam layer 12 may have a Shore 00 value of between 65 and 85 and second foam layer 14 may have a Shore 00 value in the range of 35 and 55.

[0029] According to some embodiments, first foam layer 12 and second foam layer 14 may have substantially identical length I and width « . Length t, according to some embodiments may be in the range of 80cm and 300cm. Width « may be in the range of 80cm and 300cm. Thickness t of exercise device 10 may be in the range of 8cm and 25cm. It should be appreciated that other dimensions for length t, width « and thickness t may be used.

[0030] Reference is now made to Figs. 3A, 3B, 4A and 4B. Exercise device 10 may comprise a third foam layer 16. According to some embodiments, third foam layer 16 may have a convex face 16b and a flat face 16a. Third foam layer 16 may be shaped as a half cylinder (as seen in Figs. 3 A and 3B) or a half globe (as seen in Fig. 4A). Flat face 16a may be affixed, in a detachable form, to an outer face of first foam layer 12, opposite to the face of first foam layer 12 attached to second foam layer 14.

[0031] According to some embodiments, third foam layer 16 may be attached to first foam layer 12 by means of hook and loop fastener 17 or by any other detachable affixing means known in the art. According to other embodiments, third foam layer 16 may be attached to first foam layer 12 in a non-detachable manner, e.g., by means of adhesives.

[0032] Third foam layer 16 may be harder than first foam layer 12. Third foam layer 16 may have a maximal thickness ntt in the range of 2 cm to 25 cm. Third foam layer 16 may have a length that is equal to or smaller than length I of exercise device 10, and may have a width that is equal to or smaller than width « of exercise device 10. Third foam layer 16 may have a Shore 00 value of between 60 and 90; and a compression deflection at 25% in the range of 90 kPa and 250 kPa.

[0033] Third foam layer 16 may be made of polyethylene foam block, such as Palziv Palfoam PA125 having a density of 125 Kg/m ³ , compression deflection at 25% of 225kPa and a Shore 00 value of 79. It should be appreciated by those skilled in the art that other foamed polymers may be used.

[0034] With reference to Fig. 4C, exercise device 10 may further comprise, according to an embodiment of the present invention, one or more unsmooth portions 141 on at least one side of foam layer 14, facing away from foam layer 12 when foam layers 12 and 14 are attached. Unsmooth portions 141 may be embossments of or grooves in foam layer 14, or may be separate layers of rough material, detachably connected to foam layer 14. [0035] It should be appreciated that in addition or alternatively, unsmooth portions 141 may be created or attached on an outer side of foam layer 12.

[0036] Reference is now made to Fig. 5 which is a flowchart of a method for using an exercise device according to some embodiments of the present invention. The method may comprise providing a first foam layer (block 510); providing a second foam layer (block 520); where the first foam layer is harder than the second foam layer.

[0037] The method may further comprise attaching the first layer to the second layer to be partially or fully overlapping (block 530). According to some embodiments, the attaching of the first layer to the second layer may be in a detachable manner, e.g., by hook and loop fasteners, by means of buttons, zippers and the like.

[0038] Optionally, a third layer, having a convex face and a flat face, may be attached to the first layer along the flat face of the third layer (block 540). It should be appreciated that the third layer may be attached in a detachable or non-detachable manner to the first layer.

[0039] After the first and second layers and optionally the third layer are attached, the exercise device may be placed on a rigid surface so that the second layer is in contact with the rigid surface or so that the second layer faces away from the rigid surface (block 550). The exercise device's position is determined according to the specific exercise or set of exercises that should be done.

[0040] For example, when a balance exercise is required, the third layer may be attached and the exercise device may be placed on a rigid surface such as a floor with the convex face of the third layer facing the surface, and the second layer facing substantially away from the rigid surface. In another example, the exercise device may be used as an aerobic step. In this example, the third layer may not be attached or may be removed, and the exercise device may be placed with the softer layer (i.e., the second layer) facing the rigid surface.

[0041] While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
