This week Bonnie transforms the sawhorse into something like a real horse for the fourth of a series of exercises. This one is particularly important in our present mechanized life, where the arms and hands are seldom used for anything more strenuous than pushing a button. Your first try will probably result in a quick bounce followed by a collapse onto the horse, but after a while you will be able to do it as demonstrated.
Sit astride horse, gripping crossbar with both hands. Raise your body, support weight on hands, bending knees. Hold 10 seconds.
With body held in the raised position, straighten legs and maintain balance as long as you can. Then repeat the entire exercise.
