Hinged arm muscle exercise device

Abstract

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.

What is claimed is: 
     
         1 . A muscle exercise device, comprising:
 a first arm;   a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm;   a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess; and   a wireless transmitter chip disposed in either the first arm or the second arm, wherein the wireless transmitter chip is responsive to communications from an app residing on a user device.
