The advantages of Smith's machine include that it allows you to isolate specific muscles. This is good for pure muscle exercise. This is one of the reasons why some bodybuilders use Smith fitness equipment.
Personally, I don't recommend using Smith machine.
Understand why athletes should not use Smith machines.
If barbells, dumbbells or kettlebells are used, the Smith machine will only use the protagonist muscles, and will not use any synergistic muscles. This may lead to muscle imbalance, which may lead to injury.
Because the Smith machine only plays with the muscles of the protagonist, it has a fixed path. It is not a very useful machine when it comes to proper motion patterns.
Fitness with bare hands (especially family training) is the closest way to real life, but compared with gym training, it seems lazy and inefficient.
It is convenient to exercise by hand. It's okay. You can bend over and do push-ups. Unlike gym exercise, you need to prepare all kinds of sportswear and shoes for sun protection. When you spend time on the way to the gym, you can do a whole set of unarmed training at home.
In addition, unarmed training at home can also protect privacy. This truth may not be clear to everyone, but it certainly exists, especially for many female exercisers, which is very important.
Gym is a public place, and people in it have different purposes. Like the gym incident in Wenzhou a few days ago, privacy is also an important factor in choosing whether to exercise at home or go to the gym.
As for the inefficiency, when we do unarmed training at home, we will be disturbed by many external factors, such as snacks in the refrigerator, cats and dogs at home, and the impulse to pick up the mobile phone. Sometimes I go to play with my mobile phone after I finish the action. This kind of exercise is inefficient.
In the gym, you can concentrate on training or you can train with your bare hands in the gym.
On the technical and underlying logic level, there is no difference between fitness without equipment and exercise in the gym. It is nothing more than gradually increasing the amount of training to achieve the purpose of fitness exercise. But we should remember that with the help of external equipment, we can gain muscle and lose fat faster.
So in the final analysis, the effect of unarmed fitness is slower than that of equipment training. Don't forget, in the gym, there are training partners to help you correct your movements.
