1.name the three biggest muscles in our body

1. The gluteus maximus is the biggest muscle in the human body. More commonly known as the glutes, this muscle is located behind your hips and is responsible for things like keeping your body upright and helping you walk up stairs. Basically, your glutes are responsible for most all movement of the lower body.

2. The largest muscle in your upper body, the lattismus dorsi (more commonly known as the lats) is a broad muscle located across the lower part of the back

3. Your quadriceps are another large muscle group located on the front of your thighs. They're responsible for helping extend your knees and bend your hips, and made up of four different muscle heads: The rectus femoris, vastus lateralis, vastus intermedius and vastus medialis. Your quads are key for general everyday movement, like walking, running, squatting, cycling and keeping balance. This means that a muscle strain —which commonly occurs when you overstretch or pull your quad — could leave you out of commission for a while.
