If you’re moving beyond bodyweight work, a power rack is an extremely versatile investment and offers the most safety for lifting alone—especially squats and bench presses. Space-wise, most basic models fit in a footprint of roughly 4’ x 4’ (height can be 7’+), but check your ceiling clearance if you want a pull-up bar. Prioritize solid construction, safety spotter arms, and stability (look for at least 11- or 12-gauge steel). Used racks from reputable brands often hold value well and can save money. It isn’t overkill if you have the space and intend to progress with free weights.
