I’m doing the fierce 5 intermediate plan and on lower B he has RDL. Now I love my regular deadlifts but he doesn’t list that as a substitution for the RDL. So when I do the RDL I feel a lot of my back being worked like the lower part of it. I’ve looked up videos and can’t seem to get it because I don’t think you should feel it in your back in a RDL. It wants you keep your legs straight which goes against everything when it comes to lifting something from the floor. You normally want a slight bend in the knees but with a RDL it says you want to keep your legs as straight as possible. Isn’t that going to hurt you back then? Are you suppose to feel it in your back when doing RDL? If not is the conventional deadlift ok to substitute?
