I actually had a nice article for this one, but when i saved it, it came out in boxes and circles...
anyhow,
these are a couple of programs i've used that i've got great results from!
Program One:
Semi Stiff Legged Deadlifts 3 sets 10,8,6 reps
Back Extensions 2 sets 12,10 reps
Supermans 1 set, 25 reps.
Program Two: Higher volume:
Smith-Machine Semi Stiff Legged Deadlifts: 3 sets 10,8,6 reps
Barbell Good Mornings: 2 sets, 12, 10 reps
Back extensions: 3 sets, 15,10,8 reps
A few things. WIth back extensions, go past paralal and hold for a count of 3-5 seconds on each rep. Don't go past paralal on deadlifts!!! If your goal is lower back mass, keep your legs semi-straight but not locked. Deadlift can actually work quads more than lower back, infact its like a semi-squat and can rob your lower back of workload if you don't keep legs fairly straight.
Also i find deadlifts on a smith-machine can really isolate your lower back. I do them with 4 plates on each end easily.
anyway good luck to those who entered.
And stick to your guns this week cos i'm gonna put in a killer-tri workout!
