So, I suck at squats, so I'm using the machines. At the gym there's the 'straight' leg press, versus a 'swing-like' leg press. I for some reason prefer the swing one. Good, bad, stupid? Same muscles worked?
Define "suck at squats." Not using much weight? Bad form? Both?
I know a few people that say they suck as squats and use the leg press instead. It's just their ego. With the leg press they feel strong and accomplished stacking multiple plates on the machine, where as they struggle with less than 200# with barbell squats.
OP, get comfortable doing squats. Back squats, front squats, high bar, low bar, etc. Don't worry about the numbers.
