Exercise #1:Barbell (Back) Squats
Back squats are the most obvious exercise you can do in a squat rack. In fact, the rack was invented to allow safe execution of the barbell back squat. Without a squat or a power rack, it is impossible to do this exercise safely. You need to have something to hold up a loaded barbell, so you can place it in a good position on your upper back. You also need safety pins to catch the bar if you fail your lift. So, any squat rack workout routine starts with back squats, and every good workout plan needs to have barbell squats included. But, you can use the rack to perform other types of squats too, including front, sumo, Zercher, split squats, as well as different forms of lunges. Therefore, you will use your rack to perform squats most of the time, but that's not the only exercise you can do in it.
