Mi a különbség eredmény/hatás szempontjából súllyal való guggolás és a Hack gépen való guggolás között?

"Target Comparisons

Hack squats and back squats both target the quadriceps muscles, or quads, which extend your knees. While hack squats primarily focus on the quads, back squats also target the gluteal muscles of the buttocks, the adductor muscles of the inner thighs and the hamstring muscles on the back of the thighs. In addition, because back squats require you to stabilize the barbell against gravity, they also engage your core, including your abdominal and back muscles."
