Abstract

Claims (57)

1 . A plank training device, comprising:

a base having a first height;

a foot support assembly rotatably engaged with the base;

a foot well defined by the foot support assembly, wherein the foot well is singularly U-shaped and vertically-oriented in an initial position;

wherein the foot well is adapted to receive at least a portion of a human's feet; and

wherein the foot support assembly is rotatable about an axis relative to the base.

2 . The plank training device according to claim 1 , further comprising:

a base plate of the foot support assembly adapted to support the portion of the human's feet;

at least one adjustable block adjustable relative to the base plate of the foot support assembly; and

wherein the adjustment of the at least one adjustable block defines a size of the foot well.

3 . The plank training device according to claim 2 , wherein the at least one adjustable block further comprises:

an adjustment screw releasably engaging the at least one adjustable block to the foot support assembly between one or more positions relative to the foot support assembly.

4 . The plank training device according to claim 3 , further comprising:

a first set of adjustment apertures defined in the at least one adjustable block to receive the adjustment screw; and

wherein the at least one adjustable block is moveable between a first position when the adjustment screw is secured to the foot support assembly through a first adjustment aperture of the first set of adjustment apertures and a second position when the adjustment screw is secured to the foot support assembly through a second adjustment aperture of the first set of adjustment apertures.

5 . The plank training device according claim 3 , further comprising:

a first adjustable block of the at least one adjustable block is adjustable relative to the base plate of the foot support assembly;

a second adjustable block of the at least one adjustable block is adjustable relative to the base plate of the foot support assembly; and

wherein the adjustment of the first and second adjustable blocks defines the size of the foot well.

6 . The plank training device according claim 2 , wherein the at least one adjustable block is moveable relative to the base plate via at least one adjustment aperture and is secured thereto by at least one adjustment screw.

7 . The plank training device according to claim 2 , wherein the foot support assembly further comprises:

at least one slot extending through the base plate of the foot assembly;

at least one locking device extending through the at least one adjustable block and the at least one slot; and

wherein the at least one locking device is configured to releasably secure the at least one adjustable block in a desired position relative to the base plate.

8 . The plank training device according to claim 7 , wherein the at least one adjustable block slidably engages the base plate of the foot assembly via the first and second slots of the at least one slot.

9 . The plank training device according to claim 8 , wherein the at least one adjustable block slidably engages the first and second slots together or individually.

10 . The plank training device according to claim 2 , further comprises:

at least one base block engaged with the at least one adjustable block; and

at least one screw receiver defined by the at least one base block.

11 . The plank training device according to claim 10 , further comprises:

at least one block slide rail located on the at least one base block;

wherein the at least one adjustable block is mounted on the at least one base block; and wherein the at least one adjustable block is secured to the at least one base block via at least one adjustment screw.

12 . The plank training device according to claim 10 , wherein the at least one adjustable block is housed inside a cavity.

13 . The plank training device according claim 1 , further comprising:

at least one riser removably connected to a bottom of the base in which the at least one riser and the base are collectively defined at a second height that is greater than the first height.

14 . The plank training device according claim 1 , further comprising:

a first riser removably connected to a bottom of the base in which the first riser and the base are collectively defined at a second height that is greater than the first height; and

a second riser removably connected to a bottom of the first riser in which the first riser, the second riser and the base are collectively defined at a third height that is greater than the first and second heights.

15 . The plank training device according to claim 1 , wherein the base further comprises:

a back plate adapted to engage a wall surface;

a bottom plate adapted to engage a floor surface; and

wherein the back plate and the bottom plate are engaged with and substantially perpendicular to one another.

16 . The plank training device according to claim 15 , further comprising:

at least one hole defined in the back plate, wherein the at least one hole is adapted to receive a screw that secures the base to the wall surface at the at least one hole.

17 . A method of performing planking exercises, the method comprising:

placing a base of a plank training device on a ground surface adjacent to a wall, the base having a first height;

inserting at least one of a user's feet into a foot well defined in a foot support assembly of the plank training device, wherein the foot well is singularly U-shaped and vertically-oriented in an initial position; and

rotating the foot support assembly relative to the base of the plank training device while maintaining a plank position from the planking exercises.

18 . The method of claim 17 further comprising:

adjusting at least one adjustment block of the foot support assembly to change a size of the foot well from a first width to a second width that is less than the first width.

19 . The method of claim 18 further comprising:

adjusting a first adjustment block of the at least one adjustment block of the foot support assembly from a first position to a second position;

adjusting a second adjustment block of the at least one adjustment block of the foot support assembly from a third position to a fourth position; and

defining the second width when the first adjustment block and the second adjustment block are respectively adjusted to the second position and the fourth position.

20 . The method of claim 18 further comprising:

connecting at least one riser to the base; and

defining a second height by the at least one riser and the base, collectively.
