Any good bodybuilder doesn't get caught up in any one excersise, or number.
I can use any type of means to achieve the same result....ultimately, you're looking to break down muscle by lifting weights...I don't care if the weights are freeweight, machine, cement, or two 5 gal. paint buckets with a broomstick through the middle...
Deadlifts , bench press, squats, etc...are all great exercises...if used correctly and smartly. Ironically, it's the pursuit of lifting MORE weight that has resulted in LESS people getting to their goals as a bodybuilder.
TRAIN SMARTER, NOT HARDER.
