Approach your vertical base, and get into the basic press hold. From here, kick up into a Vertical Chamber Press. Once your position is fixed, smoothly extend the legs upwards until they are locked out. At this point, your trunk and body should form an approximately straight horizontal line, with no sagging. The body won’t be totally vertical, but maintaining hold will be easier if you can get an angle that’s at least above an upwards diagonal. Hold the position, breathing normally.
