Remember - no rolly chairs for this one!
Begin sitting on a step or chair with hands next to thighs. Balance on your arms, moving backside in front of the step with legs straight (harder) or bent (easier). Bend the elbows and lower body a few inches, keeping the shoulders down and the elbows parallel to one another and at 90 degrees. Push back up to starting position and repeat.
Tomorrow - say "ow" as the muscles you forgot you had speak their mind. Do another set of chair dips and smile, because you are in control.
