Lower back feels 'pumped' all the time
Well, not all the time, but more than it should. I'm 60, 5' 10", 216 lbs. Squats in the mid-300's, deadlift in mid-400's. For the last month or two after my squat and/or deadlift workouts, my lower back has had an extreme pumped feeling for a half hour or so after the workout ends, with walking out of the gym to my car being a somewhat uncomfortable experience. I had a hard and deep massage yesterday, concentrated on my lower back and my it felt much better for the rest of the day after that. This morning, though, it felt pretty much the same as before the massage. I spent the morning working in the yard and I felt that same stiff tightness. It's not present all the time, just when standing for extended periods or bending over for a few minutes (and after squat or deadlift work sets).
Training-wise, I've been mostly doing HLM, so I never have a heavy squat and heavy deadlift on the same day, deadlifting only on the light squat day. There is never any sharp pain, just a dull, tight, 'pumped' feeling, like after holding a Superman position for a long time. Coach Santana has looked at my form (in-person and via video) and saw my knee slide in my squats as a contributing factor. I think I've learned to set my knees properly now, at least up to three plates, but I have to work on leaning over more.
I've had my share of tweaks, pulls and tears over the years, and I've always trained through them. I've deloaded from 365 for triples down to 315 x 5 x 3, concentrating on form and haven't pulled heavy for 2-3 weeks, just one session of light snatch grip DL. This is the only situation I've faced where more training has not made the pain lessen. Is this a situation where rest might be useful or should I deload even more and really get form locked in? I'm planning on competing in Santana's meet again this fall and I'm hoping this doesn't set my training back to far.
Thanks.
Lower back feels 'pumped' all the time
Bit of an update. First, here are the links to the lifts I've posted in the Technique forum:
Technique forum - Squat
Technique forum - Deadlift
I really don't think my squat is the issue as I've done 355 x 3 x 5 and 325 x 5 x 3 as my last two squat workouts and I didn't feel any soreness or tightness afterwards. Same with deadlift at 415 x 5. But today, I was moving furniture out of my daughter's apartment and my lower back became actually pretty sore and 'pumped'. When I got home, I used the electric shiatsu massager and that loosened things up again. I've tried some stretches on an irregular basis, based on Defranco's Limber Eleven, but not really seeing any effect with them.
Any thoughts from anyone on how to reduce this discomfort?
Thanks.
