this^^
i just read an article in Flex magazine about a workout called Linear Periodization and several more workouts and iv done the first month and i liked it,ive never tried anything like it in my life in essence it looks like this
1st week-3 sets of 12-15 on all muscle groups
2nd week-3 sets of 9-11
3rd week-3 sets of 6-8
4th week-3 sets of 3-5
after the 1st month,change all excercises and start all over,but start backwards.....
1st week-3 sets of 3-5
2nd week 3 sets of 6-8
3rd week- etc....
than there is another periodization the next 4 weeks with different excercises and rep schemes,....its soomething new to me and might work for you,if you've never done anything like this it might work,if you try it,you will find out which rep scheme works for you best,i think this is the idea of the whole program,good luck
4th week
