Just picked up your SSP and have a question about the shield phase. When completing the main lifts from week 1 through week 4, how many of the prescribed sets should be done til failure? For example, during week 1 for the push day, the main lift is prescribed 4 sets of 10 reps. How many of those 4 sets are recommended to be carried out to failure for best growth response - all 4 sets? Last 2 sets? Last set? How would that translate for week 2, 3, and 4?
Thank you very much
