I strained a muscle at the gym yesterday.

She started strength training for the iliococcygeus muscle.

They (referring to women or girls) are my best friends.

I go to the gym every day to build my muscles.

This river is three long.

He exercises his pectoral muscles every day.

He does exercises to train his gluteus muscle every day.

The fascia is an important part that wraps around the muscles.

I work out every day to strengthen my body.

He is doing special exercises to train his teres major muscle.
