<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. All you need is a pair of dumbbells, a bar, and a bench. You should do three sets of squats, resting for 30 seconds between each set. The author recommends doing this exercise for six weeks to get the best results.
