4. Professional advice
1.daily posture adjustments: Keep your feet parallel when standing, with weight evenly distributed on both legs; avoid buckling your knees in when sitting.
2.Targeted training: It is recommended to squat against the wall, lie on your side and raise your legs, etc. 15 minutes a day can effectively improve muscle strength imbalance.
3.Nutritional supplements: Adolescents should ensure a daily intake of 600IU vitamin D to prevent leg problems caused by rickets.

Through scientific understanding and correct intervention, most functional leg problems can be effectively improved. If you have related problems, it is recommended to consult an orthopedic or rehabilitation specialist first.
