<human>:  In the book ‘Getting Fit’, why is it that the author recommends that you do a lot of squats?
<bot>: Well, squats are a very effective way to build muscle and lose fat. They are also very easy to do. You just stand up straight, bend your knees, and then push your hips back until your legs are straight. Squats can be done anywhere, and they are great for building muscle and losing fat.
