I’ve been lifting for 2 years and have not experienced any long lasting pain and have not been injured. My progress is slow, 330/225/360 S/BP/DL at 220 BW (gained 30lbs) but I’m not in a hurry. I’ve been doing round back deadlifts for a while now (my spine has completely lost it’s natural lordosis due to a lifetime of sitting, my lower back has a slight rounding that I just can’t force into extension, my discs are completely fine and I have gained 2 inches to my height since I’ve started training) and have never experienced any back pain.
People start obsessing over their progress and start doing too much, either load or sets.
My well-being improved by a lot. Sitting for 8+ hours a day stopped being an issue and all the weird pains I had before disappeared.
