Dumbbell ni ubwoko bwibikoresho bifasha guterura ibiro hamwe nimyitozo ngororamubiri, ikoreshwa mukubaka imyitozo yimitsi. Kuberako nta majwi iyo yitoza, yitwa dumbbell.
Dumbbells nibikoresho byoroshye bikoreshwa mugukomeza imitsi. Ibikoresho byingenzi byingenzi bikozwe mucyuma, bimwe bifite reberi.
Ikoreshwa mugutoza imbaraga zimitsi, imyitozo yo guhuza imitsi. Ku barwayi bafite imbaraga nke zimitsi iterwa no kumugara, kubabara no kudakora igihe kirekire, fata amajwi hanyuma ukoreshe uburemere bwibihuha kugirango ukore imyitozo irwanya kurwanya imbaraga zimitsi.
Dumbbells itoza imitsi imwe; Niba uburemere bwiyongereye, guhuza imitsi myinshi birakenewe, kandi birashobora no gukoreshwa nkubwoko bwimikorere yibikorwa byimitsi.
Imfashanyo yo guterura ibiro hamwe nimyitozo ngororamubiri. Hariho ubwoko bubiri bwuburemere buhamye hamwe nuburemere bushobora guhinduka. Ibirangantego biremereye. Fata icyuma cy'ingurube, inkoni y'icyuma hagati, impande zombi z'umupira uzengurutse, kuko nta jwi ryimyitozo, ryitwa dumbbell. Uburemere bwa dibbell yoroheje ni 6, 8, 12, na 16 pound (pound 1 = 0.4536 kg). Uburemere bwibintu biremereye ni 10, 15, 20, 25, 30 kg, nibindi. Kimwe na barbell yagabanutse, mukabari kagufi k'icyuma kumpande zombi zuburemere bwurupapuro ruzengurutse, uburebure bwa cm 40 ~ 45 z'uburebure, imyitozo yo guterura cyangwa imyitozo ngororamubiri irashobora kongera cyangwa kugabanya ibiro. Akenshi ukora imyitozo ya dumbbell, irashobora gushimangira imbaraga zimitsi yibice bitandukanye byumubiri.
Birazwi neza ko isesengura ry’imihindagurikire y’ingufu za centrifugal rigomba gukorwa mugihe hakozwe ikizamini cyimyororokere yumubiri. Imbaraga za Centrifugal zirashobora gutuma ikintu cyambere hamwe na misa ntoya ibona inshuro nyinshi ingufu za kinetic kurenza uko bisanzwe mumwanya muto, kandi igakomeza kubyara inertia, imbaraga rero za centrifugal ntishobora gusuzugurwa. Inganda zikoresha ibikoresho bya fitness zagerageje gushakisha uburyo bwo gukoresha ubu bwoko bwingufu za kinetic ako kanya mugushushanya ibicuruzwa. Muri iyi nzira, havutse imbaraga za kinetic ingufu dumbbell yavutse. Bicamo ibyiyumvo biremereye bya dumbbell gakondo kandi bigatuma imyitozo iremereye iruhuka. Ihuza ibikorwa biranga umupira wamaboko na dumbbells kugirango itange imyitozo yingenzi yimitsi ningaruka zimyitozo yumubiri.
