I often see some people use fitness equipment in the community and parks. As the body swings, the hand grips the handle of the fitness equipment, for fear of falling. In fact, this "protective" action may bring more harm.
 The "Dr. Network Medicine" website in the United States has listed two-handed fitness equipment as one of the common sports misunderstandings. The reason is that experts believe that being too tight can not give enough safety protection, and can not increase the intensity of fitness. Grip the exercise program that only applies to some wrist joints, such as lifting dumbbells, barbells, etc. It is not the case for exercise outside the wrist, because the strength of the wrist is small in itself. When the fitness equipment is gripped for a long time, the muscles of the wrist are easily fatigued. In addition, when the hand is gripping the exercise machine, the attention will also turn to the wrist, and other parts of the body will begin to relax, while the muscle groups such as the thigh and chest will not be able to achieve effective exercise.
 Therefore, it is recommended that you do not need to use too much force when operating the rowing machine, riding an exercise bike, etc. If you are worried that loosening will affect your safety, you can put the four fingers of the index finger, middle finger, ring finger and little finger on the equipment. When you feel comfortable, release one finger. Finally, only one finger is needed on the equipment. On the top, while supporting the balance, you can achieve better exercise results.
 Need to be reminded that some elderly people or people with cardiovascular and cerebrovascular diseases, it is best to hold the handle when exercising, and it is best to be accompanied by someone around you. If you want to improve your grip easily, you can stick to heavy objects every day: hold a small bottle of mineral water or other heavy objects with your palms facing down, and then grab the heavy objects and then grab the heavy objects, so that they don't land, repeat repeatedly.
