ABSTRACT:
A portable exercise device for exercising and strengthening a user's arm and leg muscles which utilizes a spring mechanism connected to an adjustable lever arm which the user must pivot in the exercise routine. The adjustable lever arm is connected at a pivot point to a support bar which is designed to rest against the back of the user's triceps. A shoulder harness extends from the top of the elongated support bar and supports the device on the user's shoulder. There is a hand grip at the end of the shoulder harness to be grasped by the user's hand on the non-exercising arm. At the end of the adjustable lever arm opposite the pivot connection is a hand grip which is grasped by the user and pulled on in the exercise routine. The spring applies the counter force to the adjustable lever arm and is the force which the user must overcome during exercising the muscles. With a leg strap the device can be strapped to the top of the user's leg between the hip and knee. The hand grip can then receive the bottom on the user's leg and the user can do leg curls to exercise the leg muscles. By means of attaching a rigid bar to the adjustable lever arm and with the device strapped to the user's leg, the exercise device can be also used to exercise the triceps. Accordingly, three different exercises can be performed with a single device.
