i always thought looking up helped, or just lookin at yourself in the mirror. but lately, my squatting technique has improved so much, it never feels like i work out my lower back. and my squat strength has gone up, thanks for the low reps method. i squated 255! Hopefully by the end up the summer I can hit 300. But I wanna make sure I can do 235-255 in my sleep before i try something so hard as 300.
