Power Rack
A barbell rack is definitely a must for your home gym. Seeing as how you’re going to want the king of all exercises, the squat, in your routine then chances are you’re going to need a rack to put your barbell on when the exercise is complete. That being said, chances are you won’t have a spotter there for you all the time so you’re definitely going to want some safety arms to ensure that you don’t hurt yourself during a lift. The rack should be tall enough to perform a military press and a squat comfortably as well as being able to hold a large amount of weight, ideally upwards of 500 lbs.
