@tinychris00: ID: lower back itu cuma sebutan lain dari spinal erectors, dan ototnya jalan dari atas sampe bawah (seluruh back) dan yes, RDL lebih bakal bias glutes dan SLDL lebih ke spinal erectors/adductors (hamstring bakal tetep kena kok). gw gapernah nyampe 0 rir kalo SLDL/RDL, 1 rir aja, minimalkan cedera. ENG: lower back is just anothet term for spinal erectors, and the muscles goes from the top to the bottom of your back, and yes RDLs will bias the glutes more whereas SLDLs will bias the erectors and adductors more (hamstring will still be hit on both). and no, i never go 0 rir on SLDL/RDLs, just 1 rir, minimize injuries. . . #gymmotivation #breathedivinity #gymindonesia #sciencebased #fullbodyworkout
