Umatshini wokunyusa we-glute ham udibanisa ukusebenza okuhambelanayo kunye nokuzinza ngohlengahlengiso oluchanekileyo, oluchanekileyo kunye nokuphatheka okuyingqayizivele. Lo matshini odibeneyo sisixhobo esibanzi sokuzinzisa umgca ophakathi kunye nokuqiniswa kwe-hamstrings kunye ne-glutes-konke ngendlela esebenza ngokugqithiselwa kwimidlalo yomdlali.
Kanye kunye nokuqiniswa kwemisipha ngaphakathi kwekhonkco yangasemva, uqeqesho lwe-GHD luvumela enye yeendlela ezikhuselekileyo zokuqeqesha ngokusebenzayo i-spinal erectors. I-GHD sit-ups iphinda ibangele enye yezona zithintelo zesisu ezinamandla kuyo nayiphi na intshukumo kwindawo yokuzivocavoca. Uzinzo oluphakathi olufunyenwe lusebenza njengebhanti lobunzima bangaphakathi elikhusela umqolo kunye nokuphucula ukusebenza kwezemidlalo. Ubungakanani beNdibano: 1640 * 810 * 1060mm, ubunzima obunzima: 84kg. ityhubhu yentsimbi: 50 * 100 * 3mm
