Personally, if you don't practice weight-bearing squats, it will put too much pressure on your knees! Squat with bare hands, a simple instrument, is helpful for knee recovery! ! The premise is that your injury is clear to you and not too serious. You can also do slight leg movements, such as leg flexion and extension! But be sure to warm up thoroughly, jog for 5- 10 minutes, and sweat a little!
