For those who struggled in the gym, with their hands behind their head, eagerly touching their elbows, here’s the good news: the end of the reign of the abdomen comes as a standard exercise.

People with high positions of training, gurus and military specials, claim that the abdomen is too much risk of injury to the back.

A recent Navy Times editorial, an independent publication covering the US Navy, calls for the abduction of the abdomen from the compulsory examinations of readiness that the sailors must pass twice a year. The abdominal uterus is called “the key cause of back injury and obsolescence of today’s exercise”. Canadian Armed Forces kicked the belly of their fitness exam with the pretense of causing possible injury and is not related to concrete military work.

Tony Horton, creator of popular video exercises P90X, says no more belly or switches. “I really believe that traditional anti-theft switches are outdated and time is changing,” says Horton.

Sleepworms can burden the spine and an additional 50 kg – says Stuart McGill, a biomechanics professor at the Canadian University of Waterloo. In dozens of published research, Dr. McGill has found the forces that combined with repeated bending in the abdomen can squeeze the discs into the spine. This can result in time by swapping the discs, pressing on the nerves and spinal problems, leading to the sniffer of the disc.

For people who want to do abdominal exercises from the traditional starting position for the abdomen, Dr. McGill advocates a customized exercise – which he himself thought – with his hands on the lower back and shoulders almost to the floor.

The abdomen can be performed in several ways, including the switches and abdomen in a stable position or with a pilates ball. The risk of injury depends on the exact movement and the limitations of the individual exercising. Some fitness instructors dismissed even those modified abdominal muscles.

The plank has come out of the yoga box and is used largely in physical training instead of the abdomen. The stance resembles the top position of the skull with a body flat from the heel to the shoulder. It also works with the forearms on the floor.

Plank uses the muscles on the front, side and back of the central body, while the belly activates only a few muscles, experts say.

Captain David Peterson, Executive Director for Physical Education at the US Navy Academy, the proponent is the plank position in their physical fitness exam. In 2013 he wrote an article in the Strength and Conditioning magazine and advocated the board because it is less of a risk of injury and more important for naval operations.

When we do normal jobs, Captain Peterson says, we usually stabilize the abdomen so we can pull more power from the central body to lift, pull, push, and carry. When we look at it, then we see that the abdomen does not prepare for it either for functioning on the battlefield. He emphasized that this was his opinion, not the opinion of the entire navy.

Canadian armed forces in the last year of long-term endurance testing have a task such as lifting sandbags of 20 to 30 kg for 3 and a half minutes.

“We went further than measuring the power itself while running the abdomen and the skeletons,” says Patrick Gagnon, Senior Human Performance Manager at Canadian Armed Forces. He says the new exam more precisely predicts how well the soldiers will do their job.

One study of 1,500 US troops showed that 56% of the injuries to the three-part fitness examinations associated with the abdomen. The Runway Test 3.2 km was associated with 32% of the injuries, and the slips with 11% of injuries. Overall, 8% of all soldiers were injured.

Tummy skulls remain in the ordinary check of physical fitness exams for the American Air Force, Army, Navy, and Navy, though three of these examinations are under revision. Exercise in the Coast Guard includes belly but is only required for certain placements.

Over the last few years, the army has been conducting probation testing for 10,000 troops and excluding the abdomen from their fitness exam. While the military is investigating the best solution to measuring soldiers their basic readiness, it keeps the classic three-part examination principle: swords, abdomen and running at 3.2 km at a given time, says spokeswoman.

Mariners and Navy also consider elements of their exams. Marines will collect recommendations by July 1st. The Navy has no deadline for possible changes to its exams, says Lieutenant Joe Keiley, a public affairs officer for major naval operations.

“Definitely we are looking for ways to improve,” says Lieutenant Keiley.

Many Americans first performed abdomen as part of a program known as the Presidential Youth Fitness Program, a multi-year program that was a multidisciplinary exam for schoolchildren.
