Description
Technical Field
The invention relates to the technical field of fitness equipment, in particular to a tumble injury prevention fitness device.
Background
With the rapid development of the society, body building becomes a part of daily life of people, and the body building brings a lot of benefits, and frequent body building can help to lose weight, remove redundant fat of the body, enhance the content of muscles, shape perfect figure, enhance the immunity of the body, improve the sleep quality, and effectively help people to build body and exercise by using the body building device.
At present, the user can use fitness equipment to carry out the auxiliary exercise when carrying out the body-building activity usually, though fitness equipment can play good exercise effect, but fitness equipment is at the in-process that uses, because the user is too big at the in-process waist strength of taking exercise, and take exercise for a long time, lead to consuming self too much physical power to make the user take place the condition of tumbleing because the health is unbalanced on fitness equipment easily.
The user is when using body-building apparatus, because body-building apparatus's length is fixed, when the user is carrying out normal health when taking exercise, the length that the health stretches out outwards can be longer for the user is when using body-building apparatus to take exercise, its focus position is comparatively high, and when the strength that the user used is great, will produce great forward inertia, because inertial existence makes the user turn out forward easily, and then brought hidden danger to user's safety.
The outer surface of a common fitness apparatus is usually wrapped with a layer of rubber ring to protect a user, however, the softness of the common rubber ring is low, the buffering and matting effect on the abdomen of the user is poor, the user can easily feel obvious discomfort on the abdomen of the user after a long-time use process, and then certain harm is easily caused to the abdomen of the user, so that the common fitness apparatus needs to be improved and optimized.
