Makina opalasa ndi chipangizo chophunzitsira chomwe chimatsanzira kupalasa m'madzi. Kupalasa m'nyumba kwasanduka masewera aukadaulo. Makina opalasa m'nyumba amadziwikanso kuti ergometers (omwe amadziwikanso kuti Ergo kapena ERGO m'maiko akunja), omwe amagwiritsidwa ntchito poyesa mphamvu zomwe othamanga amagwiritsa ntchito panthawi yochita masewera olimbitsa thupi [1].

Makina opalasa amathandiza kulimbitsa minofu ya miyendo, m'chiuno, m'miyendo ya pamwamba, pachifuwa, ndi msana. Kugunda kulikonse kudzamaliza kupindika kwathunthu ndi kutambasula miyendo ya pamwamba ndi yapansi, m'chiuno ndi m'mimba, ndi msana, zomwe zimapangitsa kuti minofu yonse ikhale ndi mphamvu yochita masewera olimbitsa thupi. Masewera olimbitsa thupi a makina opalasa ndi othandiza kwambiri kwa anthu omwe ali ndi mafuta ambiri m'chiuno, m'mimba, ndi m'manja.

Mukapalasa bwato, muyenera kusamala kwambiri za kusinthasintha kwa mayendedwe anu. Kukwapula kulikonse ndi kutambasula kuyenera kuchitika pamalo ake, popanda kuyimitsa. Minofu yomwe imagwira ntchito pakuyendako sidzatambasulidwa kapena kufupika kwathunthu ngati kutalika kwake kuli kochepa kwambiri. Zimatsanzira mayendedwe achilengedwe a kupalasa bwato ndipo ndizoyenera kuchita masewera olimbitsa thupi komanso masewera apakhomo, kuchita masewera olimbitsa thupi a manja, miyendo, chiuno, ndi ziwalo zina, kuchita masewera olimbitsa thupi otambasula minofu, makamaka msana wapansi, zomwe zimatha kuchepetsa zizindikiro za ululu wammbuyo.
