Let's face it, using the Glidecam is an isometric exercise. Most of the Glidecam, their counterweights, full-size SLRs, good glass lenses, batteries and mics all add up and wear out the muscles in your arm. This device helps to reduce wrist strain and balance the weight of the rig. While this won't save your biceps from pain, it will make the overall experience more comfortable and make a long day at work just that little bit shorter. Enjoy!
