ABSTRACT:
An exercise device includes a resilient plate body, a pair of handles, a pair of V-clips and a flexible adjusting sheet. The plate body has a protrusion integrally and transversely formed on a middle portion thereof, and defines a pair of inclined through holes each between one of two distal edges of the plate body and the protrusion. The protrusion defines an arch therethrough which has an opening in communication with an undersurface of the plate body to receive the adjusting sheet. The pair of handles each has a metal rod encased in a sponge tube. A distal end of the metal rod extends through a respective inclined through hole of the plate body. Then the V-clip grippingly fastens the respective distal end of the metal rod. The flexible adjusting sheet is shaped to be received in the arch of the protrusion. An inner periphery of the adjusting sheet is configured to have stepped portions, such that a thickness of the adjusting sheet increases from a first end thereof to a second end thereof with the progression of the stepped portions. With this arrangement, the exercise device can provides multiple resistance options.
