A squat machine is designed to help you train your quads, hamstrings and glutes, without putting a heavy bar on your back or having to worry about balance and safety. 

If you insist on squatting for a few minutes every day, you can strengthen the muscle strength of your legs and also enhance your body's metabolism, helping your skin excrete waste and garbage, from making your skin more hydrated and lubricated. It makes you look younger and thus has an anti-aging effect.
