To digress a bit. I think the SLDL, particularly if the lifter stands on an elevated platform, is the penultimate exercise for the posterior chain. No exercise works more tissue/musculature. The dead-hang power clean is close, but it's not the same.

However, no exercise is done incorrectly as much as the SLDL. And...because of that, it causes a lot of injuries and faulty results.

To digress even further, I also believe the crazy bastardization of the power clean has made that fine posterior chain, total body exercise problematic for most trainee's.

All of that said, if you do not have the inclination to do the SLDL, dead-hang power clean and power clean correctly, don't do them at all. You can get all that you need for posterior chain work from swings, deadlifts and shrugs. (Preferably heavy dumbbell shrugs!)

End of rant.
