My desk surface is as close to knee level as possible, so about two feet off the ground. The desk is an electric standing one, so I can regularly stand or sit. My chair allows for full support of my hamstrings and let's my foot sit flat on the ground. I try to maintain a vertical posture. I use a Microsoft eurgonomic 4000 keyboard. My monitor sits high enough to be at eye level. I also do power and Olympic lifting several mornings a week. Additionally, I have a forearm gadget for rolling out the muscles there called an Armaid Extreme Foam Massage Tool with Orange Ball Myofascial Release Tool (Trigger Point Therapy for RSI in Forearm and Upper arms).
