I love front squats- but form is the most important thing here, so swallow your pride if you are going to seriously incorporate these into your normal routine.
Back need to be straight, lean too far forward and you can fall like a bag of bricks. Abs need to be in, feet should be apart straight ahead so you can go at least parallel with these. The hardest part for most is finding where the bar is going to sit on your clavicles and what your hand positioning will be. For me, the bar sits in an indentation perfectly. I use the cross over hand positioning , some guys like to under over position and that is fine. If done properly, you should really feel it in the front part of the quad.
Again form is key here, I have seen some guys try to rack up 270 right off the bat(because they can do 270 with regular squats) and they make asses out of themselves because the bar ends up falling forward because of shitty form, or weak back or weak abs. Longtime ago when I used to have a partner we used to do 100 count front squat reps to begin quad work. Weight was light but after 50 it seemed like it was 1000 lbs. There was no stopping , you could pause for a second, then keep moving. I never got so sick in my entire life. Yes you feel like a puny ass for only squatting 135 but the burn in the quads was phenomenal. Some guys like to do it on the Smith machine, but I can't get the bar to sit properly on my clavicle and my hand positioning does not feel right, so I don't use it.
Good luck if you incorporate these into your rotation. It may be a while before you can actually add some serious weight on the bar.
