The mechanical function of this invention uses the centrifugal force of rotating weights. The weights are attached in the same position on the end of the bar and connected internal by a steel shaft through the center of the bar that is held in the hands of the user. The bar that is held is a steel tube with bearings in the end sleeves. The internal steel shaft with the weights attached turns inside the bearing. Once held and worked in a circular motion by a person the weights will start spinning. The higher the Revolutions per minute the greater the force against the person using it resulting in a cardio and strength training workout at the same time.

This invention relates to hand held dumbbells such as those found in gyms useful in body building.
Hand held rotating dumbbells are popular with body builders. However existing hand held rotating dumbbells are somewhat irregular in the impact felt when in use by a bodybuilder. Some have addressed this with adjustments for fine tuning.
As will be seen from the subsequent description of the preferred embodiments of the present invention the present invention has significant advantages over prior art.
The preferred embodiment of the present invention uses the centrifugal force of rotating weights. The weights are on the end of the bar and are offset. The weights are attached and connected internally by a steel shaft through the center of the bar that is held in the hands of the user. The bar that is held is a steel tube with bearings in the end sleeves. The internal steel shaft with the weights attached turns inside the bearing. Once held and worked in a circular motion by a person the weights will start spinning. The higher the revolutions per minute the greater the force against the person using it, resulting in a cardio and strength training workout at the same time.

The concept arose while carrying a 54 lb 5 foot banded bundle of small diameter flimsy wire ties. When walking it would start bouncing and rotating on the ends.
Step 1. Insert bearing (#6
Step 2. Insert bearing (#3
Step 3. Place sleeves with bearings on end of tube (#5
Step 4. Press Sleeves onto tube, Tube will rest against inside bearing.
Step 5. Insert ½″ steel shaft (#2
Step 6. Press rotating weights (#1
Step 7. Align both weights to same position on each end of bar.
Step 8. Weld weight to end of ½″ steel shaft.
Although the descriptions above contain many specificities, these should not be construed as limiting the scope of the invention, but merely providing illustrations of some of the preferred embodiments of the invention.
It will be obvious to those skilled in the art that modifications may be made to the embodiments described above without departing from the scope of the present invention.
