    •  DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring now to the drawing, my exercise bar includes two collapsible hollow cylindrical left end pieces, a similar right end piece as shown in FIG. 8, and a cylindrical center piece as shown in FIG. 5. The center piece includes hand grips 3 at each end along with a locking mechanism. Said locking mechanism may be nut not limited to a screw mechanism or bolting mechanism which may also be unlocked as commonly known to persons skilled in the art. Additionally the center portion of the center piece includes an adjustable tension mechanism 1 to provide resistance to the bar being contorted from its linear shape. The tension mechanism 1 may be but not limited to a tension spring, polymer material with high resistance to bending and returns to its original shape as commonly known in the art. The end pieces include locking mechanisms at their ends for selective engagement with the center piece. Either end of each end piece can thus be the locked onto the center piece. Removable end caps 5, 11 are attached into the outer ends of the end pieces to insert additional weights.
  • The end pieces 9, 3 include a hand grip at each end and on the opposing end additional weights may be inserted into the body or looped onto the outer surface. These are handgrips for the user. The preferred exercise with the two end pieces detached from the center piece may be used as a weighted Billy club exercise. The user may simulate traditional marital arts movements within his exercise. Said end pieces are collapsible to adjust length depending on exercise or for storage concerns. The small portion of the end piece 3 inserts into the hollow of larger end piece 9 and locks into place. Any form of locking mechanism as mentioned above may be utilized
  • Additionally one end piece may be selectively being attached to the center piece for additional exercises as shown in FIG. 7. This form allows the user to simulate exercises similar to marital arts sword exercises, baseball movements, tennis movements as well as other traditional sports or martial arts techniques. The adjustable tension mechanism along with the weight parts creates a tensional imbalance which the user must utilize additional muscle groups to control the movement of the apparatus.
  • The center piece alone may be used for an exercise in itself. The center tensional mechanism 1 is adjustable for increasing the strengthening and toning activities. In accordance with the invention, there is provided an exercise device including a pair of nonaligned hand grips which are rotatably mounted on a nonlinear bar and tensional mechanism which may be a spring-biased to provide adjustable resistance to motion through predetermined symmetrical strokes. The device preferably includes detachable auxiliary weights 5, 11 which enable the total weight of the device to be adjusted the spring biasing force applied to the grips is preferably individually adjustable for each grip. The orientation of the biasing means, enabling symmetrical movement of the grips against spring torsion, enables the user to move both arms and hands in identical, symmetrical motion in an exercise, with either the same force resisting torsion of each grip, or a selected difference in the tensional resistance between the two grips by adjusting proximity of said grips. The further the distance of the grips from each other, the more reduced the tension of the spring. The springs are preferably coil springs which are disposed within the respective grips. In accordance with one feature of the invention, the grips are biased for rotation by a pair of torsion springs disposed internally of the grips to apply torque to the grips such that the grips may be reciprocated symmetrically with respect to one another. The center piece as shown in FIG. 5 allows the user to simulate martial art techniques with additional resistance and user added weights. Said martial art techniques may also be in the form of nun chuck exercises.
  • Additionally with both end pieces attached to the center piece as shown in FIG. 6, exercises similar to martial arts staff techniques and traditional aerobic movements like rowing may be simulated additionally with an unstablized core created by the tensional mechanism creates more challenges during the movements. Additionally users may add additional weight onto said staff further enhancing said workout.
  • Said entire center piece may be collapsible within the center hollow of the end pieces. Additionally the end pieces collapse into themselves reduces the length of the end pieces by half. In fully collapsed form said apparatus can be easily stored. Workouts may also be done with the apparatus in different collapsed stages.
  • For aerobic movement, the bar is used with un-weighted end pieces of weight W and center piece of weight M. For muscle toning activity, weighted pieces are used, up to a maximum of five additional pounds in the center piece and each end piece.
  • The end caps are rubber tipped to provide friction for a non-slip use of the bar, as where the bar is used as a support.
  • The exercise bar is a multi-purpose exercise and fitness device. It is used as a non-weighted bar for aerobic movements and routines. It is used as a weighted bar for specific muscle strengthening and toning activity.
  • The foregoing description of a preferred embodiment of this invention, including any dimensions, angles, or proportions, is intended as illustrative. The concept and scope of the invention are limited only by the following claims and equivalents thereof.
