I have a problem when I do heavy squats. About half way up when I start to struggle with the weight, my knees will go inwards. Then once I get past the part I was struggling they'll go back out.
Is it ok that they do this?

try taking a wider stance and placing all your weight on the outsides of your feet as opposed to your heels or the balls of your feet .. or (gasp) the insides of your feet
focus on this you should be fine
Thanks for the quick response! I'll give it a try on my next squat day.
yea it's normal, that's your sticking point
take a wider stance like glen said and point your toes out 45 degrees. also when going down force your knees out and on the way up force your knees out also. just keep forcing your knees out. also throw in the ab/adductors(good girl/bad girl) machines. do a set of 25 on each machine. and as always squat below parallel. anyone that tells you not to squat past parallel is wrong and it will just end up hurting you
Don't let your knees come in like that. A good way to fix it is by using a miniband. The band pushes the knees in so the natural reaction is to push out.
The thighs tend to adduct due to weak abductors, meaning your glutes are weak or extremely fatigued, but most likely the former. You need to get those glutes up to par, especially the gluteus medius. Maybe you should incorporate unilateral work in some workouts such as lunges and Bulgarian squats.
Oh, I would also highly suggest adding in dynamic warmups for your legs and glute activation exercises to get them firing properly, if they are not already.
Maybe I just have the wrong idea, but aren't those machines meant more for girls? I'm seriously asking.Originally Posted by guyfromkop2
Would I put bulgarian squats in place of regular squats? Or would I throw them in afterwards?Originally Posted by Ibanez
Also can you elaborate on dynamic warmups? I've never heard the term before.
Can one really hurt themselves by having these knee movement through the squat? I do this sometimes as well, have been for years and never suffered any knee painOriginally Posted by jjm
yes, your knees can buckle and once you get some decent weight on your back it will just torque your knee and blowouts will happenOriginally Posted by MiKeY ReSp

and never substitute out regular squats.
dynamic warmups are basically warming up with the excersize you will be doing, just use low weight.
