Yes, you could get that weightlifting workout in while you’re on set, but 4 out of 5 producers (and lawyers) agree that such a decision would make them question your sanity. 
 
The Vario 5 with STABIL G2, Standard Gimbal Rig Vest & Quick Release from Easyrig features the Vario 5 power pack, STABIL G2 foldable shock-absorbing arm, and standard-size Gimbal Rig Vest, which is designed with a wide front that fits around the waist and over the hips. The standard vest offers a waist adjustment range of 33 to 47". Also included is a quick release camera mount instead of the standard one.

The Vario 5 has an integrated 35" suspension line and offers tension adjustment on the rear for 11 to 38 lb loads. The STABIL G2 Arm is included in place of a standard arm. It's designed to hold your camera load while also smoothing out shots. It also has a built-in stand hanger that allows you to set down your entire rig on the edge of a film cart or other surface with a similar edge.

The quick release comes with two 3/8"-16 and two 1/4"-20 ball studs. The threaded ends of these ball studs can be screwed into top handles and other supports that offer a matching threaded hole, and the quick release attaches to and removes from the ball ends by quick release.

The body-worn Easyrig system takes the load off your shoulder, neck, and arm muscles and distributes it across your torso for easier operation over long periods.
