Deze 30 kg halterset (25 mm!) is ideaal om spierkracht te ontwikkelen. Je kunt de halterset aanpassen aan je eigen niveau, de set wordt namelijk geleverd met 8 schijven van 2,5 kg, 4 schijven van 1,25 kg en 2 halterstangen.

Te licht of te zwaar?
Een bekend fenomeen in iedere sportschool is het volgende. Fanatieke, vaak nog wat onervaren sportschoolbezoekers voeren oefeningen - zoals 'biceps curls' - uit met veel te zware gewichten. Hun hele lijf schudt van voren naar achteren om de dumbell te kunnen liften. Hiermee wordt aan het doel van de oefening: het isoleren van één spiergroep, volledig voorbij gegaan. Rugblessures liggen dan op de loer! Als je bedenkt dat 's werelds meest beroemde bodybuilder, Arnold Schwarzenegger, een groot deel van zijn biceps training uitvoerde met gewichten van 8, 10, 12 en 14 kg, zal je beseffen dat 15 kg per arm voor de meeste mensen voorlopig ruim voldoende gewicht is en eerder te veel dan te weinig. Mocht je toch zwaarder willen trainen, dan kun je uiteraard voor een appel en een ei een paar extra gewichtsschijven aanschaffen, die je moeiteloos op de halterstangen schuift.
 
Diverse oefeningen 
Met dumbells zijn talloze oefeningen mogelijk, die je in staat stellen om vrijwel iedere spiergroep te trainen. Om een paar voorbeelden te noemen: biceps curls en triceps extensions voor je armen, dumbell presses, upright rows en lateral side raises voor je schouders of dumbell squats voor je benen.
 
Dumbells vs machines
De belangrijkste reden waarom veel professionele sporters kiezen voor het trainen met losse gewichten, zoals dumbells, is de eindeloze variatie en het feit dat het lichaam niet 'geholpen' wordt door een machine, die de bewegingsvrijheid beperkt. Bij het trainen op machines blijven de spieraanhechtingen bovendien achter in de ontwikkeling. 
 
Met de halterset kun je efficiënt trainen, zodat je spieren zich symmetrisch ontwikkelen. 
 
NB Deze Gyronetics halterset bestaat uit halterschijven met opening van circa 25 mm en halterstangen met doorsnee 25 mm. Deze maat wijkt af van het reguliere assortiment van Gorilla Sports dat bestaat uit 31 mm / 50 mm schijven en stangen.

All Gotchas, Gimmicks, and Grief
My husband broke the item in question, which was a Chemex coffee maker made of nothing but glass. It shattered full of coffee, so like a normal human he cleaned up the dangerous mess and threw it away. I put in a claim, and it said that I had to ship back the product. Believing that the Asurion process was as simple as stated, and reading the agreement that does mention that sometimes they'll require shipment of the item, but that they will review cases and use reasonable judgment, I contacted their chat, explaining that the requirement that I mail them a wet pile of shards of glass soaked in coffee (and a little bit of blood) was unsafe and unreasonable. I don't even know how I could do that in a way that would be safe for the people opening the packaging, or even to take it to the store. The shards of glass might puncture any plastic, and the wetness would soak through, plus there's the biohazard issue. Seems silly for a $47 product replacement to me. I figured any human would understand. First chat associate closed my case without even responding to me. I had to reopen it. The second one told me, "Yes, that is how your warranty works" as an answer to my "Hello, the last chat closed without me talking to anyone." I tried to explain the situation, and was told "If you call the hotline, maybe they'll help you." I call the hotline. The first person tells me tough, I have to mail it. I say it was thrown away. He says "AHA then it's lost! Your warranty doesn't cover lost things!" I say no, it's not lost, it was disposed of properly as shards of glass should be. I finally ask can I speak to someone else or a supervisor. He lies and says yes. I sit on hold for 20 minutes, never any wait time or any sort of indicator of when someone will talk to me. The phone call quality finally gets very horribly staticky, so I hang up and try again. Hallelujah, I get a decent human being who immediately says, "Oh, no, that's not reasonable! That is an unsafe thing to have to mail. I'll send it to the override department who should approve this because it's obvious that's not a normal thing to expect." Today I get an email that says: We can't approve your claim. We reviewed your NO SUPPORTING MANUFACTURER COFFEE MAKER claim. The product in your claim is not covered by your plan. As a result, we're unable to approve your claim. Nothing about the requirement to mail a biohazard, just the item isn't covered even though the item is absolutely covered. While I understand that loss prevention is important, this is a very small potatoes return and it isn't like I made this up. It would be easy to make me happy. I'm sure it has cost them more money to deny it than they would have lost covering the Chemex. I've bought multiple of their product replacement policies before. I never will again. They didn't offer for me to send a picture or anything. They just wasted hours of my time and sent a clearly AI-based answer, rather than treating me like a valuable customer.
