Matsui Kaoru (judo restorer, director of Nintendo Wii Fit sports series) uses isometric contraction to effectively exercise muscles, and applies local pressure for 5 seconds at a time to quickly strengthen muscle strength. The theory of "5-second slimming exercise" is based on the isometric contraction of muscles, which keeps the muscles contracting in short-term exercise, so as to increase the tension inside the muscles and produce rapid muscle strength. Simply put, this is a training method to keep the muscles contracting continuously and achieve the purpose of concentrated exercise. Common mechanical fitness exercises are difficult to implement, and muscles and joints are also prone to burden. But the unarmed training in this book can achieve better results and will not cause joint burden. Of course, you don't need to spend money to go to the gym or use dumbbells and other equipment to assist. "Muscle isometric contraction" is a static exercise, which was originally used for rehabilitation, because as long as the posture is maintained in the process, it will not move to the joints quickly, so that people with weak muscle strength or lack of exercise habits can go smoothly, breaking the established impression that exercise is often "tired = effective and thin". People with poor physical strength or those who just want to lose weight in certain parts can simply have a look and not be too tired. The five characteristics of the 5-second slimming exercise can be done anytime and anywhere because there is no need to prepare props, and it can be done at home or between companies. Even some actions can be performed at the same time as work or housework. Once you get into the habit, you can definitely see the change of your posture! Exercise takes a short time. Using the training method of putting pressure on muscles in a short time, as long as it is as short as "5 seconds", the moving parts can feel very much. No matter how busy life is, you can always find time to do it. You can concentrate on the part where you want to lose weight. The biggest advantage of 5-second exercise is that you can train a single part efficiently. Focusing on the target muscle for a short time can quickly see the local effect, which is the most suitable exercise for carving the ideal body shape.
