Design engineers аre usuаlly mоre fаmiliar with safety hazards because the effects оf оverlooking these hazards are much more obvious than those resulting from health hazards being overlooked.

(1)Many people who do sit-ups may not be getting the full benefit of the exercise because they’re doing them incorrectly. (2)Here are three common sit-up errors—and what should be done instead. (3)One error is allowing the stomach muscles to bulge out, rather than tucking them in. (4)Doing this repeatedly can cause the muscles to stay stuck out, rather than flattening, which is the goal. (5)To make sure your stomach muscles are tucked in while exercising them, try pushing your tummy into your back—that’s what it should feel like. (6)Another error is not breathing while doing sit-ups. (7)Many people instinctively hold their breath during physical exertion—so they don’t get the oxygen necessary to fuel an effective workout. (8)The proper (and easiest) way to breathe during sit-ups is to inhale for the easy part (lowering your back) and then to exhale during the hard part (lifting yourself up). (9)A third error is keeping the legs straight, which uses—and can strain—the lower-back muscles, rather than making full use of the stomach muscles. (10)For safer, more effective sit-ups, keep those knees bent. The pattern of organization of the above selection is.
