If it is relatively less strenuous exercise, some people can take a hot bath.
But for high-intensity exercise, we must do a good job of warm-up exercise to ensure that the ligament is not easy to strain. So keep your body completely warm.
Some people find their own warm posture. For example, if I go swimming, I can run a short distance in the swimming pool or take a bath with hot water.
Any warm-up association should be based on personal physique, surrounding geographical environment, climate change and so on. However, as long as you exercise regularly, you will definitely sum up a set of warm-up exercises of your own in constant practice.
