I tried my FIRST 12 rep workouts this week. Monday i did legs and tuesday i did chest/bi's. I noticed a few things. I am accustomed to the 6-8 rep range, never really going higher. I do 4x12 or 3x12 on the exercises in this new workout, the burn and strain is so much more intense then the lower reps/higher weight. I am able to push 230 10 times on one set on flat bench, however i had to toy with 185 down to 180, to 165 to 135 to complete the 4x12 on my first exercise. I was completely shocked on how much strength i DID NOT have when doing the 12 reps. The soreness is still there, i've never been sore from a chest workout, or bicep, and im really sore now. I also noticed that my biceps and chest were A LOT bigger from the pump of blood, however, about 10 minutes after my workout i noticed it was completely gone and i felt like i did not workout, except that im sore as hell today. I was curious what you all think about this and if that means i went to high in the reps. I think im going to cycle a periodization of two weeks of 12 reps then 10 reps then 8 reps then 6 reps then a few days off and back up to 12? My goal is to gain size/mass and add some strength, i'd like to have a bodybuilder's physique, big, round, solid, massive yet still be able to push heavy weight like the big boys. thanks!
