What is the foot expansion machine?

The foot expansion machine is a piece of exercise equipment that insulates the four -headed muscle muscles. When using the foot extension machine, an athlete sits in a machine with a knee slope behind the upholstered rod and then straightens the leg to train the muscles in the thigh. Some machines for expanding the legs work individually and others are designed to function both legs simultaneously. Some of the foot extension machines use pulleys so that the athlete can change the weight using the standard PIN system and other machines allow athletes to load the weight plate directly into the extension mechanism. It is also common for a foot extension machine part of a larger piece of exercise equipment, such as a combo machine for extension of the bench or leg/leg. If this is the case, the seat usually does not have his back, while most of the separate nobles prolongation provides some support back. Sometimes these machines provide a belt for athletes to lift a large amount of weight the right lever effect.

For the use of an extension machine of the foot athlete first loads the weight and sits on the seat. If the machine has a belt, the athlete should turn it around the waist. The athlete then bends his knees, usually slightly at an angle of 90 degrees and places his legs behind a padded rod. The bar should rest in the curve of the foot where the leg meets the shin. The athlete should then capture the handles or sides of the seat for added stability.

From this starting position, the athlete begins to completely straighten the legs by lifting the lower leg. The resistance provided by a padded bar should load a quadruple during this movement. The athlete must be careful to maintain the stable speed of movement so that the legs work all the time. If an athlete needs to generate momentum to fully extend his legs, it should reduce the amount of weight. Once the legs are straight, the athlete should bend the knees again and return to the starting position.

Quadravís is relatively strong withThe valve group, so the foot expansion machines must be able to support a large amount of weight. For this reason, it is important to ensure that the foot expansion machine is stable and that the construction is of high quality. The joint that attaches the padded bar to the seat can sometimes relax, so it is important for the athlete to ensure that the joint is stable and that the rod does not water when it is in motion.
