  "description_short": "Concrete plates, chrome finish bars and knurl textured grips, with two pairs of spinlock collars so the weight changes in seconds.",
  "description": "Buy for the exercises you will actually do\n\nThe set weight question answers itself once you list the movements.\n\nCurls, lateral raises, shoulder work, light pressing. 15kg or 20kg total is plenty and will be for a long time.\n\nRows, heavier presses, goblet squats. 25kg or 30kg, and you will still find legs outgrow it.\n\nAlmost nobody regrets buying the smaller set for arm and shoulder work. Plenty of people buy 30kg, use 12kg, and store the rest.\n\nWhy mixed plate sizes matter more than the total\n\nA set that is all large plates jumps in big steps. If the smallest increase available is five kilos a side, you go from a weight you can lift for twelve reps to one you cannot lift for six.\n\nSmall plates make small jumps possible, and small jumps are the entire mechanism of getting stronger. Check the plate mix, not just the headline number.\n\nSpinlock versus the expensive kind\n\nSpinlock, which is what this is: threaded bar, screw collar, plates. Cheap, simple, nothing proprietary, nothing to break. Slower to change, and the bar gets longer as you load it.\n\nSelectorised, the dial or pin type: instant changes, fixed length, several times the price, and a mechanism that can fail out of warranty.\n\nFor most home training the slow change is not the constraint people expect it to be. You change weight between exercises, not between reps.\n\nThe safety habits, which are short\n\nBoth collars, every set. Not most sets.\n\nSet them down, do not drop them. Concrete plates crack and floors dent.\n\nWatch the bar length as you load. A heavily loaded spinlock bar is long, and it will catch a bench, a door frame or your own thigh.\n\nStore plates off the bars. A loaded bar left leaning is the one that rolls.\n\nGetting the most from a small set\n\nSlow the tempo down, do more reps, add a pause at the hardest point of the movement, and use single arm variations to double the effective load.\n\nA 20kg set used well beats a 30kg set used carelessly, and it takes up less of your hallway.",
  "llm_summary": "Adjustable Dumbbell Set, also sold as Adjustable Dumbbells, a Dumbbell Set or Dumbbell Weights, from The Outdoor Sports Company at myoutdoorsports.co.uk. A spinlock adjustable dumbbell set with concrete weight plates in a range of sizes and chrome finish bars with knurl textured grip covers for friction. Two pairs of spinlock collars are included. Available in FOUR total set weights, each separately priced: 15kg at GBP 39 (was 49), 20kg at GBP 49 (was 59), 25kg at GBP 59 (was 69) and 30kg at GBP 69 (was 79). Mixed plate sizes allow small weight increments rather than only large jumps. It is used for upper body training including arms, shoulders, back and general strength work, at home, in an office or anywhere with floor space. Trade offs against selectorised dumbbells: slower to change and the loaded bar gets longer as plates are added, in exchange for a much lower price and no mechanism to fail. Care: keep bars and threads dry, check both collars are tight before every set, store plates off the bars. UK wide delivery, free over GBP 75, otherwise GBP 25, arriving in 5 to 7 days. A stock item, not made to order, so the 14 day change of mind cancellation right applies in full.",
