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. De schijven worden stevig vastgezet met de metalen schroefringen, die het totaalgewicht van 30 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, 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.

From a Long Time Hard Sole Dress Shoe Wearer, These are a Must Have!
Size: 12, Color: Blue
I have been wearing hard sole dress shoes for decades and with the full COVID shift to dressing super casual in a professional work environment, I was in the market for some more casual let dressy shoes that were a heck of a lot more comfortable and flexible than my hard soles so I thought I would give this brand and style a try. Oh man, I'm in love. These give you that dressier look yet you can totally dress them down with jeans or cordouroys, so versatile. As I did with my hard soles, I inserted one of my Nike Air in soles and man, these are so comfortable I bought navy and brown! I usually wear these with thin dress socks and they go perfectly with any type of suit set, a no brainer purchase here. I'm a 12 and bought a 12, perfect fit, not to skinny, not to wide, just right. Bottom sole grip is impressive, never felt unstable, solid rubber sole here. I decided to lace them up so there are not tying and the tongue does slip down sometimes so with this feature, best to use a metal shoe horn, then it's super easy to slide them on, they seem to take a beating and remain clean too, I've definitely scuffed them up against many things and still no damage, it's crazy, must have a great finish. NOTE TO Note to MANUFACTURER/SELLER - You need to make a version in GRAY in this specific style and I will buy them instantly, and I assure you they will be incredibly popular! Really not sure why there isn't more colors in these like gray, shades of gray, maybe red, lighter blue and maybe some with different tones in standard colors. Casual dress shoe wearers are looking for new and exciting bold colors so this is the perfect shoe type to deliver on that.

Finally, a dress shoe that actually feels like a sneaker!
Size: 8.5, Color: Dark Brown
I was honestly super skeptical about buying shoes on Amazon, especially "dress sneakers." Usually, they either look incredibly cheap in person or they completely destroy your heels within an hour. I am so glad I took a chance on these Bruno Marcs.
I commute to campus and take the bus almost every day, so I end up doing a ton of walking. I needed something that looked sharp and put-together, but I absolutely refused to sacrifice comfort for a long day on my feet. These completely hit the mark. Right out of the box, there was zero break-in period—no stiffness, no pinching, and no blisters.
They are incredibly lightweight, and the material actually looks premium, not like that shiny, fake plastic you sometimes get at this price point. The traction on the bottom is surprisingly good too, which is a lifesaver when I'm rushing to catch my bus on rainy mornings.
If you’re on the fence, just get them. It’s rare to find a shoe that balances looking professional with feeling exactly like your favorite weekend sneaker. Easily one of the best wardrobe purchases I've made in a while!
