Back Squat - 4 x 6...

Back Squat @ 4x6...

4 x 6 – around 75% of 1RM (Across) @ 260lbs
Then, 1 x 12 – Take 90% of 4 x 6 @ 235lbs
1x12 @ 235 is a 10lb PR from last week! 
“If the same depth, just below parallel, is used for every rep of every set, then you know that if your squat is going up you are getting stronger”.-Mark Rippetoe
