I am setting up a strength training cornerHealth

Task prompt

I am setting up a strength training corner of my garage and want a spreadsheet tracking real candidates before I buy anything. Find 4 candidate adjustable dumbbell pairs, 4 candidate adjustable weight benches, and 4 candidate power racks, each category sourced from at least 2 different retailers' own live product pages, not an aggregator, a review roundup, or a search snippet. A dumbbell pair counts only if each dumbbell adjusts using a dial, pin, or selector mechanism built into the dumbbell itself, meaning no manual threading of individual plates on and off, and it must adjust up to at least 80 lbs per dumbbell as stated on the spec page, sold as a pair of two. A weight bench counts only if it offers flat, incline, and decline positions all three, with an incline angle of at least 60 degrees and a decline angle of at least 10 degrees as stated in the spec section, a stated weight capacity of 800 lbs or more, and folds down for storage, meaning the frame hinges to noticeably reduce its footprint, not just a bench that happens to be liftable. A power rack counts only if it is a four-post design, meaning four vertical uprights forming a full cage around the lifter rather than a two-post open squat stand, explicitly stated as freestanding and usable without bolting to the floor or wall for stability, includes integrated safety spotter bars or pins as a built-in part of the rack rather than a separate purchasable accessory, has a stated weight capacity of 700 lbs or more, and has a footprint of 48 inches by 48 inches or less as stated on the spec page. The setup is one dumbbell pair, one bench, and one rack, and the combined total price must come in at 2400 dollars or less. The final output should be a populated spreadsheet or tracker with one row per candidate, every field filled in from the live product pages, and a clearly marked recommended combination with the arithmetic shown for how it meets the budget. If fewer than four candidates in any category can be verified against every stated requirement, report the shortfall and include only candidates that can be fully verified rather than relaxing any constraint.
