I've been weight training for 30 years, although you probably wouldn't know it by looking at me.
I have been hampered by back problems for virtually the entire period, and having tried chiropractors, 'Bowen Technique', 'Active Release' etc. I finally got a proper diagnosis from a sports physiotherapist. It took him about 3 minutes to sort me out: I have one leg 1.5 cm longer than the other
The leg length discrepancy in entirely above the knee and thus any exercise where the weight is coming through my back and I am rotating on my thighs is a problem. So unfortunately regular squats and deadlifts are out
Anyway, I have to say, back pain aside, I have enjoyed every minute of it
