Hi Jim and all,
Very quick background: My deadlifting over the years has always been low reps (usually sets of 3), and anything higher I did with the trap bar or as RDL. I'm 170 lbs, with a DL max of 385. In terms of my 531 history it is using the Beyond template, where your supplement lift is different than your main lift (531 OHP + 5x3 FSL DL's, for example).
I'm doing a program in the 531 Forever book that calls from 5 PRO's + 5x5 FSL on the main lifts. With the warm ups, that's 11 sets of 5 on the main lift. No problem except for the DL's. I am very sore and achy and stiff in my lower back for days. I like to play sports and do yoga, and the stiffness and aches are making these activities more difficult. Also, I am 43 if that matters.
1) Should I stick with the prescribed rep scheme, and perhaps drop my TM on DL until I adjust to the volume?
2) Should I do sets of 3 with the DL like I am used to, instead of the 5 PRO's and 5x5 FSL like the other lifts?
3) Should I take a break from the DL, and substitute rack pulls or TB DL's?
Thanks in advance for any advice.
