Deze 15 kg halter van Gietijzer is ideaal om spierkracht te ontwikkelen. Je kunt de halter aanpassen aan je eigen niveau, de halter wordt namelijk geleverd met 4 schijven van 2,5 kg en 2 schijven van 1,25 kg. De schijven worden stevig vastgezet met de schroefringen, die het totaalgewicht van 15 kg completeren.

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, zul 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.

De Gyronetics Gietijzer Dumbell 15 kg in detail:
1 x Dumbellstang:

  • 35cm lengte
  • 25 mm doorsnee
  • Opnamegebied: 10,5 cm
  • Binnenmaat handvat: 12,5 cm
  • Gewicht 1,5 kg
     
  • 2 schroefsluitingen
  • 4 halterschijven van 2,5 kg
  • 2 halterschijven van 1,25 kg


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.

Bringing a 1976 MG Midget to the modern world!
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
I've been restoring a 1976 MG Midget barn find. I bought some Sinless liner to help make the car rattle less and feel more solid. This product is easy to cut, easy to install, and extremely sticky. I used it to line the trunk, the interior, and even some under the hood of the old MG. The adhesive stands up to the brutal temperature of the engine bay, and when (by accident) some fuel spilled onto the foam, it didn't fall apart or turn to mush. Thanks to Siless, the MG now feels like a modern car. The floor pans feel much more solid, the doors make a heftier thud when you close them, and the trunk no longer sounds like a percussion instrument when you touch it. If you know what you're doing, this product will transform the feel of a car. I found that 36 sq ft was enough for my MG Midget, but for a bigger car I would want more. The pattern on the back helped me to cut perfectly measured squares and rectangles. The foam itself doesn't have a strong odor, it works super well, and has held up to several months of changing temperatures (in the Midwest US.)
