1, before and after training, leg press, exercise your joints well and stretch more.
2. As recommended by everyone upstairs, I soak my feet. I sometimes add something like safflower to the water. . .
3. When you sleep at night, put your feet on the pillow or something.
I don't exercise much. Sudden exercise of leg muscles will definitely cause all kinds of discomfort. Just stick to it for a few days. I hope I can help you.
