--Ekubuyiseleni ubuhlungu, ukusebenzisa amathuluzi okwelapha ngokomzimba kuvame ukubekwa phambili phezu kokulungiswa kokungalingani kwemisipha kanye nezinkinga ze-biomechanical njengamasu okulawula ubuhlungu besikhathi eside.Amathuluzi amaningi okwelapha ngokomzimba okwelapha ubuhlungu abhekana kuphela nezingxenye zomzimba zomzimba;azihlinzeki ngemininingwane ephelele yokwelapha ukungakhululeki kwamalunga okujulile kanye nemisipha.
--Esikhundleni sokugxila kuphela esicini esisodwa sobuhlungu, ukwelashwa kobuhlungu kufanele kube okuphelele.(Imbangela eyinhloko ayibhekwana ne-theory yokulawula isango ikakhulukazi.) Ukuqala ngenkinga eyisisekelo, ikhambi kufanele libhekane nokushiyeka kokusebenza kanye nokukhathazeka kwe-postural ngesu eliphelele elidlulela ngaphezu kokukhululeka kobuhlungu.
