Every Monday and Thursday we post a 20 rep back squat program that we have been doing at CrossFit Mayhem for a little while.
This program starts on the first day by finding 60% of your 1RM. Do 20 reps of back squat unbroken. You cannot put the bar down and you should not rest for minutes at a time.
Every day you do this after (for us Monday and Thursday), you add 5# to your bar. Do the 20 reps unbroken. As long as you are successful, continue the program. Once you can no longer do 20 reps unbroken. You are done!
