Iv moved gyms and began using the pendulum squat which i really enjoy as i can go extremely deep safely without my back rounding as the backpad gives me feedback. However compared to a barbell squat/front squat/ hack squat i can barely load it up to “heavy weights” as even one plate feels heavy on the oendulum whereas on the hack i can put three plates a side. So my question is despite the weighr difference will the muscular stimulation be the same or is there a distinct differenfe between the two exercises regarding the weight
