Thanks for the help fellas.
I definitely don't like supersetting squats with RDL's, but I am doing Thibadeau's Superhero program which prescribes this pairing. I will try to improve my form with the wall drill, though.
Also, what is better to use, dumbbells or barbells? I first started with a barbell, but it didn't feel right, so I switched over to dumbells and felt a little better.
