Choosing a rack
A power rack decides what the rest of your garage gym can be. Look at three numbers before the price: the upright size, the hole size and the rated load. Upright and hole size decide which J-hooks, spotter arms and attachments fit. The rated load tells you how much the frame is built to carry on its hooks and arms.
A full cage gives you four posts and a safety bar on each side, which is the setup to choose if you squat and bench alone. A cage needs floor and ceiling, so measure both before you choose.
