Looking for Good Squat/Deadlift Form

I’ve recently started squats/deadlifts, and although I think I’ve got the form down, sometimes I rely too heavily on my back which I know is a sign of bad form.

Does anyone know some good guides? I’ve been doing back squats and stiff-legged deadlifts.

Also, I’m a teenager. About 170lbs, if that makes a difference at all.

Deadlift 1RM: ~260lbs
Squat 1RM: ~240lbs




p.s i got these from this website i did not find them

Thank you. I’ll have to bump down my weights and practice my form for a bit with these.
