The standard action requirements of the frog lying down are as follows: the thigh should be at right angles to the body, and the calf should be at right angles to the thigh. Tighten the abdomen and support the ground with both hands. Most importantly, gravity should be placed on the hips, not on the hands. Then breathe slowly and relax until your hips touch the ground.

Note: 1, it will be difficult at first. If you can't do it, don't force it to avoid strain; 2. Do the frog squat in a soft place; 3. Get up slowly.

Frog prone has many advantages, such as promoting blood circulation, increasing the flexibility of legs and helping to shape the body. However, we should do it step by step, and don't pursue standardization excessively, otherwise it may backfire, and in serious cases it may cause ligament strain, so we should do what we can.
