My living space is limited, so I bought a pair of adjustable box dumbbells (5-75lbs) and a skookum collapsible bench. The stowed combo occupies less space than a chair and they give me serious workout mileage: bench press, flies, rows, sit ups, skull crushers, military press, curls, lunges, deadlifts, etc. It's a great starter gym for us mere not-power-lifter mortals. I WFH and can do sets during breaks and boring meetings.
