    • DETAILED DESCRIPTION OF THE EMBODIMENTS
  • Referring to FIGS. 2 to 4, a multifunction gymnastic apparatus 1 includes a resilient fiberglass sheet 10, a covering 20 wrapping the resilient fiberglass sheet 10, and two handles 30 connecting two ends of the resilient fiberglass sheet 10. The resilient fiberglass sheet 10 is slight than the metallic spring 10 a of the conventional gymnastic apparatus 1 a, and a recovery force of the resilient fiberglass sheet 10 is less than that of the conventional gymnastic apparatus 1 a thereby. Thus conditions of the two handles 30 accidentally damages a user are decreased, and the multifunction gymnastic apparatus 1 can be operated for a long time due to the lightweight thereof. The covering 20 is made of buffer materials.
  • Whereby the user can manipulate the two handles 30 of the multifunction gymnastic apparatus 1 with his hands to fold the resilient fiberglass sheet 10. The resilient fiberglass sheet 10 will recovery to an original state after release, and the user can have his muscle into physical training with a reciprocating action of the multifunction gymnastic apparatus 1.
  • Illustrated in FIG. 5, the user has his arm and pectoral muscles training by forcing on the two handles 30 with arms. To bend the resilient fiberglass sheet 10 with arm and pectoral muscles, and to release the resilient fiberglass sheet 10 then the resilient fiberglass sheet 10 back to an original state thereof. Repeating the two states of the multifunction gymnastic apparatus 1 and the user can have his muscle into physical exercised.
  • With respect to FIG. 6, the user has his arm muscles training by forcing between the two handles 30 with hand. To shake the multifunction gymnastic apparatus 1 leftwards and rightwards, and to repeat the vibration of the multifunction gymnastic apparatus 1 and the user can have his muscle into physical exercised.
  • Referring to FIG. 7, the user has his arm and abdominal muscles training by using the multifunction gymnastic apparatus 1 arranged abutting against his back. To bend the resilient fiberglass sheet 10 with arm and abdominal muscles, and to release the resilient fiberglass sheet 10 then the resilient fiberglass sheet 10 back to an original state thereof. Repeating the two states of the multifunction gymnastic apparatus 1 and the user can have his muscle into physical exercised.
  • Referring to FIGS. 8 to 10, the present invention provides a multifunction gymnastic apparatus 2 that includes a resilient fiberglass sheet 12, a covering 22 wrapping the resilient fiberglass sheet 12, two handles 32 connecting two ends of the resilient fiberglass sheet 12, and two extension rope adjustable devices 40 arranged with the two handles 32 correspondingly. Each of the two handles 32 has a connecting portion 322, and each of the two extension rope adjustable devices 40 includes an engaging block 42, a regulator 44, a mat 48 and a retractable rope 46; wherein the retractable rope 46 has an end connecting in the regulator 44 and an opposing end penetrating through the regulator 44 and the mat 48 to the engaging block 42, the engaging block 42 accommodates with the connecting portion 322 correspondingly; whereby the retractable rope 46 is capable of expansion and contraction alternatively.
  • The resilient fiberglass sheet 12 is made of resilient materials and slight than the metallic spring 10 a of the conventional gymnastic apparatus 1 a, and a recovery force of the resilient fiberglass sheet 12 is less than that of the conventional gymnastic apparatus 1 a thereby. Thus conditions of the two handles 30 accidentally damages the user are decreased, and the multifunction gymnastic apparatus 2 can be operated for a long time due to the lightweight thereof. The covering 22 is made of buffer materials.
