I like the 5x5 system, but to those of you who do this, do you work up to the 5x5 or what? Do you just jump right into to the work sets? My flat bench 5 rep max is 235, should i just jump right into that weight for 5x5 after my warm up (medicine ball throws and jump rope/exercise bike)? Or should i do a few warm up sets of like 135, 185 and so on? And on an unrelated matter, just curious does anyone have any short video clips of how to properly do a good morning? I can't shake the feeling i'm not doing these right. Thanks.
