I heard about this workout to raise your max...
10 sets of 5 on the main lift for each muscle group using a 5 day split
ie..
mon- chest(bench)
tues- back(bent over row)
weds- off
thurs-shoulders(shoulder press)
friday-arms- bicepts(ez bar curls)tricepts(close grip bench)
saturday-legs(squats)
sunday- off
All 10 sets you need to make sure you can get all 5 of the lifts so its lower weight of course..
