Good stuff, one key factor was stated frequently: go to muscle failure. I like it
I agree. I have been cycling through rep ranges. 1st week 12-15, 2nd week 9-11, 3rd week 6-8 and 4th week 3-5. Then start over again. I have saw gains in strength and size.
I f***ing hate 12 to 15 rep ranges. That whole week sucks for me.
