Gym refers to a place for fitness, rehabilitation and exercise activities. Generally speaking, there are complete facilities, comprehensive fitness and entertainment programs, professional coaches to guide and a good fitness atmosphere. The construction, ancillary facilities and operation management of the gymnasium shall meet the requirements of the current laws and standards on fire control, safety, hygiene and environmental protection promulgated by the state.

Regular aerobic exercise is good for health: reducing the risk of obesity and diabetes, strengthening the cardiovascular system and possibly avoiding the occurrence of Alzheimer's disease. However, the problem is that many people don't get the maximum benefit from exercise during their daily exercise, either the equipment operation method is wrong or the exercise rhythm is wrong.

For example, if the resistance is set too high when using an elliptical machine, you will feel uncomfortable unless you lean on the machine to borrow money. Although you can achieve enough exercise intensity by challenging yourself, it doesn't mean that you won't have such an effect with a natural pace and a light grip. In fact, this is true of any tool.

Scott Danberg, a fitness instructor at the Prittie Jin Jiankang Center in Miami, suggested that if you want to make the exercise more difficult when using the elliptical machine, you can gently hold it with one hand, let go of the other hand and alternate from time to time. As for those books or videos, you'd better wait until after the exercise, so that you can concentrate on the action.
