See, now i've never gone Max heavy with front squats. The most ive ever gotten to was 365 i think, and it was a failed attempt. I'd Argue that staying in the hole vs coming up all the way changes the exercise, as for what it targets particularly (general quads, Insertions, closer stance for sweep, etc).
Anyone reading this thinking 'Oh im gonna give front squats a try,' just know that it is just like any other exercise. you tweak something and it changes the exercise. If you want to go heavy and do low rep sets while returning to starting position, fine, Inc Quad Rape. And that's totally fine.
If you want to go lighter, stay in the hole, and pound out 10-15rep sets, prepare for something that is the equivalent of Constant Tension Bicep curls. You are gonna get a tidal wave of blood in your quads.
Either way, it is gonna hurt/feel great. Id definitely suggest to give both a shot.
