Tsepamisa maikutlo holim'a sephutheloana sa li-dumbbells tse ntšo, ka kakaretso ka hare ho na le tšepe ea kolobe (e tlaase bakeng sa ho qhibilihisa tšepe e qhibilihisitsoeng, e bohareng bakeng sa ho lahlela matlakala a tšepe), ka ntle e phuthetsoe ka rabara e ntšo ka mor'a lefu la ho lahla.Li-dumbbells tse phuthetsoeng ka rabara li batla li arotsoe ka mefuta e 'meli, e' ngoe ke tlhahiso ea sekhomaretsi.E 'ngoe ke ho etsa sekhomaretsi se secha.Lintho tse entsoeng hape tse kopantsoeng le rabara ea litšila e nchafalitsoeng, rabara e ncha e kopantsoeng le rabara e ncha.Phapang ea theko e ka bang karolo ea 30 lekholong.Li-dumbbell tse tloaelehileng 'marakeng kapa ho khutlela ho sekhomaretsi se senyenyane.Sena ke leha taba ea hore li-dumbbells tsa polasetiki tse nchafalitsoeng li na le monko o kotsi ha o bapisoa le li-dumbbells tse ncha tsa polasetiki.Ho tsofala habonolo, ka mor'a koetliso, matsoho a tla ba le masala a monko le lintlha tse ling tse mpe.Empa theko e theko e tlaase, kahoo e rekisoa hantle.Ka mor'a matsatsi a mabeli sebakeng se pholileng, monko o batla o nyamela.
Ho phaella moo, holim'a dumbbell e ncha ea sekhomaretsi, ka mor'a koetliso ea ho hlakola, e khanya haholoanyane.Ho tlamahane ho fapane.Thepa e ka holimo ea sekhomaretsi dumbbell ke ho le bonolo ho tsofala, ka mor'a ho sebelisoa nako e telele, kopana bohale bump, ka 'na theola sengoathoana e nyenyane,' me sekhomaretsi se secha se ke ke.Empa li-dumbbells ha li atisa ho kokota lintho, sena ha se seo ho haelloang ke sona, metsoalle ea pragmatic e reka sekhomaretsi sa morao-rao se ka finyellang litlhoko tsa koetliso ka ho feletseng.
Mohato oa 3: Lintlha
Ha u reka li-dumbbells, senotlolo sa ho ela hloko lintlha tse peli, e 'ngoe ke matšeliso a ho sebetsana le ho se thelle.Ka kakaretso molamu oa grip o tla koaheloa ka lera la sekhomaretsi se khahlanong le ho thella, ho boetse ho na le khatello ea molamu oa tšepe ho tsoa moleng o khahlanong le ho thella, ka hohle kamoo ho ka khonehang ho bona hore na grip e phutholohile ebile e matla, sekhomaretsi sa anti-slip se ke ke sa khona. e be e teteaneng haholo, ho ts'oaroa ho bonolo haholo, ho seng joalo ho tla ama botsitso ba dumbbell ea grip, anti-slip line e ke ke ea apara matsoho.Anti-skid ha ho hlokahale ho bua ho eketsehileng, ho tšoara dumbbell e boima, liphello li tebile haholo, esita le haeba lehlohonolo le sa ka la otla batho ka ho lekaneng ho otla litene tse seng kae mokatong oa lehae.
Tse peli ke grip rod lipheletsong tse peli tsa lesale la screw e tsitsitseng.Ho hlahloba ka hloko hore na ho loma ha screw le screw thread ho tiile, tekanyetso ke hore screw e ka kena le ho tsoa habonolo, empa e sa sisinyehe.Lesale la screw le lona le lokela ho tiisoa ka nako efe kapa efe nakong ea thupelo.Lipoleiti tse ling tsa li-dumbbell li tla potoloha ebe butle-butle la lokolla reng ea screw.
Ho loketse ho khetha li-dumbbell tse ngata
1. Khetha boima ba dumbbell ho latela bophahamo le boima ba hau.Ka kakaretso, reka ho latela bolelele le boima ba 'mele.Haeba u sa tsebe ho khetha, u ka bua ka melao-motheo e latelang, e hlophisitsoeng ho ea ka 'mele o tloaelehileng le matla a ho ikoetlisa a batho ba Machaena, ha ho nahanoa ka karolo e tlang ea dumbbell ea ho ikoetlisa ka matla.Bophahamo bo ka tlase ho 1.60m boima 60kg-25kg motsoako bophahamo ka tlase ho 1.70m boima 70kg-30kg motsoako bophahamo tlase 1.80m boima 80kg-35kg motsoako bophahamo ka tlaase ho 1.90m boima 95kg-45kg motsoako
2. Khetha litekanyo tsa li-dumbbell ho latela sepheo sa hau sa ho ikoetlisa
Haeba boikoetliso ba hau ba dumbbell bo etselitsoe ho haha mosifa, etsa 5 ho ea ho lihlopha tse 6 tsa 8RM-10RM letsatsi le letsatsi.
Haeba boikoetliso ba hau ba li-dumbbell ke ho matlafatsa 'mele oa hau, etsa lihlopha tse 5-6 tsa 15-20RM ka letsatsi (palo ea lihlopha mona ke ea ho bua feela).
RM: e bonts'a palo e kholo ea ho pheta-pheta.Palo e phahameng ea metsamao eo dumbbell e ka e etsang ka boima bo fanoeng e bitsoa RM.RM hangata e hloka tlhahlobo e phetoang ho fumana.Ka mohlala, mochine oa khatiso oa benche oa 30 kg o nang le boholo ba 8 reps o bitsoa 30 kg upslope dumbbell bench press.
