Strength- Back Squat 4x5@LastWeek +5#
A) Warm up before the 4x5
*5-10 reps very light
B) Set 1 can be light but this should not be a warm up
C) Sets 2 & 3 should be at last week's final weight. If last week's "last set" was too easy you should use last week's weight on set 2 then add 5# for set 3
D) Set 4 should be last week's weight + 5#. It is a hard but doable set with a spot. (If you added weight on set 3 then set 4 should be 10# heavier then last week.)
*Ascending in weight. Last set should be heavy.
