It's hard to argue against RDLs when it comes to hamstring and overall posterior chain strength and development.
The biggest drawback of RDLs is that they can be tough on the lower back. If that's the case, try doing them with a trap bar, or if that's not possible, from a dead stop in the power rack.
You can also try doing them for higher reps at the end of your workout so you don't need as much weight, which even with lighter loads serves as one hell of a brutal finishing exercise, especially when using the constant tension method.
This exercise teaches you to hold the shoulder girdle rigid to avoid strength leaks in pressing lifts. It strengthens the front delts, rotator cuff, and even the lats.
To win the war on der chest, we must attack it, Blitzkrieg style! We shall crush the pectoral enemy, see it driven before us, and listen to the lamentation of the vimmen!
Didn't it seem that the bodybuilders of yesteryear had bigger chests? (We're talking chest circumference here and not pec size, mind you.) Ellington thinks so and he knows why - it was all due to the all-but-lost art of ribcage expansion.
