The best way to train thigh muscles is to squat with weight. If you can't go to the gym, you'd better have another person to practice with you. You can let another person ride on your arm. . ) and then start doing squats. Remember to keep your feet apart (shoulder width) when doing squats, and your waist must be straight, otherwise your waist will be bad. Each group has 8~ 10, and you can have any number of groups. If you have calves, you'd better go jogging, although I don't like running very much, hehe.
