Dumbbells
Buy and sell dumbbells in Guatemala.
Dumbbells here are priced the way a hardware store prices nails: by the pound, and often for a single unit rather than the pair, so a listing that looks cheap may be half of what you need. Rubber hex pairs, chrome handles that take screw-on plates and dial sets that fit a whole rack into two blocks all change hands here, new and pre-owned. Most are stamped in pounds, a few in kilos, and listings do not always say which. Iron does not wear out, which makes a used pair one of the safer buys for a home gym.
Fixed hex dumbbells against the adjustable kinds:
the fixed rubber hex is a cast iron head under a rubber coat, welded or pressed onto a knurled handle, with flat sides that stop it rolling away between sets. You buy one pair per weight, which is fine if you use three or four weights and a problem if you want them all. A spin-lock dumbbell is a short threaded chrome handle with plates held on by screw-on collars. It is cheap per pound and adjusts to any weight, but changing mid-workout means unscrewing two collars per hand. Dial or selector dumbbells, the kind Bowflex SelectTech made famous, leave the plates in a cradle and pick up only what you dial. The light vinyl and neoprene ones sit closer to the mats and bands in yoga and pilates, and the benches and racks to build around any of them are under exercise equipment.
Pounds, kilos and the pair that is only one dumbbell:
most dumbbells sold in Guatemala are stamped in pounds, but kilo-marked rubber dumbbells sit on the same shelves, and a kilo is more than twice a pound. Ask which unit before you agree a price, and look for the stamp on the end of the head in the photos. Ask too whether the price is for one dumbbell or two: shops list many hex dumbbells by the unit, and private listings copy the habit. Anyone who keeps training outgrows a light first pair, and that is the real case for spin-lock or dial dumbbells.
Why iron is sold by the pound:
with a fixed dumbbell the weight is the product, so new rubber hex dumbbells run around Q11 to Q15 a pound and a pair of 25s comes to roughly Q550 to Q750. An unbranded dial-adjustable pair that goes up to about 24 kilos a side is around Q2,400 new: more than a few fixed pairs, far less than the rack it replaces. Used fixed dumbbells go for less per pound, not because they have worn but because the buyer takes on chipped rubber, a possible loose head and a trip across town; a clean pair with tight heads deserves close to new money. Dial dumbbells lose more, because the plastic cradle and the selector are the parts that break, and nobody fixes them at home.
Twisting the heads of a used dumbbell:
hold each fixed one by the handle and turn the heads against each other. Any click, rattle or movement means the joint between handle and head has let go, and it only gets worse: that dumbbell is scrap whatever it weighs. Rubber split at the corners from drops on concrete is cosmetic until the iron shows through, but a strong chemical smell that never fades marks cheap rubber that will scent a closed room. On chrome handles, run a collar along the full thread; stripped or rusted threads mean collars that work loose mid-set. With dial dumbbells, try every setting, lifting straight out of the cradle and tilting the dumbbell to check that no plate hangs loose. Copies of the well-known designs are common, and a hand-held luggage scale in your pocket settles whether the plates weigh what the dial says.
Listing a pair, a full set or a rack of hex dumbbells:
put the weight and the unit in the title, and say plainly whether the price is for one dumbbell, the pair or the whole set. Photograph the stamped end of each head, the handles close up and the set together on its rack if it has one. For dial dumbbells, add a short video changing weights and say whether the stand comes with them. A buyer coming in from Cobán for a full set will check every pair for a loose head, so lay them out in order of weight rather than piled in a box.
