alright bro some leg tips from yours truly...technique lol.
Legs take time but when they're strong its rewarding and all your lifts will go up. My legs are particularly strong because I played ice hockey and rugby all my life. Try being gthe driving force of the srcum and your legs will explode lol.
Tips: now this is for me personally...
1) more is not better. If you squat, do not leg press or vise a versa. Either the squat or leg press will be your big multi joint movement, also after proper warm up make it your first exercise.
2) strong glutes!!!!! I have a huge a$$. Black girls are jealous lol. Strong glutes will be your driving force. To achieve strong glutes use your heels to drive. Example: on the leg press put your feet so your toes are slightly off the sled and you are forced to push with your heels. This will add serious mass and strength to your glutes. Hack squats are another great glute work out.
3) drop your weight with squats and go a$$ to mouth, I mean ground =) slowly build your way back up to going heavy.
4) strong lower back...keep dead lifting heavy like you are and strengthen your core.
5) for squats and leg press pinch your shoulder blades back and keep that nice arched back (not a rounded back, that's injury)
6) romainian dead lifts= glutes and hamstrings...avoid stiff legged deads, IMO you are just asking for injury.
7) always where a belt and with heavy weight, hell any weight wear knee wraps. They honestly feel amazing. Your knees will thank you and you will feel moreconfident to push more.
8) GO HEAVY. NUFF SAID.
