This isn't playing into the strengths that nature gives us, and explains why activities such as writing on a blackboard in a neat hand, painting a portrait, throwing a fast ball high and inside or hitting a slider are very difficult activities. And it explains why very few of us do them well. It also explains why it is ergonomically useful in preventing injuries to the muscles, nerves, fascia, tendons, ligaments and joints of the upper extremity to avoid such efforts. If an activity such as typing demands motor function primarily by the fingers, and only slightly by the hands and wrists, then we should try to keep every part of the upper extremity proximal to the wrists completely out of the picture. Chop wood with your shoulders, lay the fire with your hands.
Static loads require a muscle to fire for a prolonged period of time without relaxing.
To see for yourself what a poor job people do of imitating statues, trying drinking your morning cup of coffee by holding the cup at arm's length between sips. If the COG is in front, the back muscles are firing continuously. A guaranteed eventual result is low back pain, since the support mechanism of the back is a continuum of muscle from the coccyx to the base of the skull. It needs frequent airing to cut back on muscle injuries caused by stress loading of the back and shoulder muscles. These are generally misdiagnosed as repetitive movement injuries but are actually related to static load demands on muscle.
