@finnfierro I can't do dead lifts due to an elbow injury. I can't straighten my arm, so it puts the wrist at a terrible angle when doing dead lifts resulting in new injury and pain for weeks.
I have to be VERY careful not to progress too fast for upper body lifts so I don't reinjure my elbow. I had a radial head resection. Im literally missing 1/3rd of my elbow. So what most people do for a normal progression I just can't. And that's okay. I would imagine you would need the same care in squats.
I alternate between wendler 531 and p90x3 depending on my goals. Taking a good break from lifting as I reach new highs in my squats, bench, and press is good for my joint health and seems to work for me. I can't do some exercises in p90x3... So I skip them. And that's okay. I'm doing 26 minutes of a 30 minute workout. I'm just not going to do plyo pushups because they hurt my arm. So I skip things like that. I imagine the agility workout in p90x3 with a lot of jumping would be similar for you. If I just need to skip a day because it hurts that's fine. After an injury cut yourself a lot of slack. You aren't a quitter unless you stop going back. The 'no pain no gain' approach works when you're 18. Not 30+.
I can't do dead lifts in 531. I do bent rows. I'm able to keep my wrist straight in that motion. I incorporate good mornings on bent row day to make sure to hit the same muscle groups that dead lifts would as much as I can and within reason. It seems to be working. I'm missing 1/3 of my elbow, yet I'm the strongest I've ever been. Progress is slower than I want it to be, but hey, it's all good. I'm making progress and I feel good.
I STOP when it hurts and I only count pain free reps towards progress. This is critical. Working through the pain is important but ONLY under the safety and guidance of a physical therapist. In the weight room joint pain is bad. Always. Muscle burn is good. Joint pain is bad.
