Background

The strength training, also called as resistance training, is the oral training of stripping iron, lifting iron and apparatus, and also includes the bare-handed dead weight training. In most people's cognition, strength training has only two effects, one is muscle building (i.e. increasing muscle circumference), and the other is increasing strength. In fact, strength training can also be used for fat reduction as well. Unlike most common aerobic exercises such as running, elliptical machines, rowing machines, skipping ropes, etc., training can be started directly without special training, with few doorsills. The strength training is different, the equipment is more, the action is more, and the technical points of use and training are more. Moreover, the mastering and familiarity of the technology requires a lot of training and experience accumulation, and can be done immediately without reading, understanding or understanding the writing and others. The action is not in place, so that the training effect is influenced or even no effect or negative effect is generated, and the potential training risk is generated, for example, some novices like to blindly adopt heavy weight. Taking the smith machine as an example, it is believed that there may be some people mixing it with a squat frame. Because they are all seemingly composed of a barbell bar and a frame body, but the difference is that the barbell bar of the squat frame is movable, namely a standard bar; the barbell bar of the smith machine is a bar which moves along a fixed track and is not detachable. However, with the current conventional smith machine, it is generally believed that it may make deep squats and bench presses dangerous and unnatural, but may be a very effective strength training instrument, provided that appropriate guidance or guidance is available.
