In fact, the support plate of sit-ups is a common fitness equipment, which was invented for abdominal training. But there are some safety problems in the purchase of supine board, because it needs to support your body after all. If the supine board is not strong enough and safe enough, it is likely to bring some harm to the body when doing sit-ups!

1. Select a supine board with a solid board surface:

In fact, the most important part of the supine board is a board face of the supine board and its support frame, so its board face design needs to support the core of our whole body, and a fulcrum when we do sit-ups is a board face of his supine board. Although our legs are stuck by its support, in fact, we mainly use our waist and abdomen to exert force. Furthermore, we need to see if one side of his supine face can bring us comfortable and efficient exercise effect under its own conditions, because many supine faces are similar, but our bodies are different. Tall people will choose some longer supine boards, while short people will choose some shorter supine boards, but generally the surface length is about 130cm and the width is 40cm, which needs to be considered according to their own height.

2. Choose a supine board that won't shake, and see the maximum bearing capacity of the material:

In fact, the second point of choosing a supine board is to see whether his supine board can support the maximum weight of our body and whether it can stay there stably. If we sit up and do sit-ups, he is not stable enough, but swings back and forth, which is easy to cause us some risks. The second is that everyone's weight is different. It is necessary to see whether the material of the supine board can bear its own weight according to its own weight, which is also a necessary condition to avoid injury!
