Squats work by stimulating your the lower extremity muscles especially the gluteal muscles and the leg muscles. It is used for strength, stamina and muscle building.
quads (narrow squats) & gluteals & hamstrings (wide-positioned squats)
mainly your legs but and your back a little
Squats and poly-metrics.
Hamstrings, quads, calf and abdominal
Yes, Because you are squatting
Squats and deadlifts will work your gluteal muscles (as well as many other muscles).
By putting your body in different positions you can workout almost all muscles including your back muscles by doing a back extension with dumbbells or the most common exercise squats which workout your legs
Squats are one of the best, if not the best, exercises you can do. This is because they work so many muscles, while forcing you to stabilize and balance your body under a heavy load. The primary muscles involved are the quadriceps, hamstrings, glutes, and adductors.
Squats will make your thighs and but appear stronger because they make the muscles in those areas stronger.
You probably haven't been using those muscles that you don't use a hole lot of. You just need to keep doing your squats to build up those muscles so then after you do your squats... they won't hurt. Trust me... my arm is really sore from softball pitching... it's just because i haven't been using those muscles for awhile and i need to strengthen those muscles :D
Hamstrings, Quads, Calves.
