Thought I'd already wrote this but it hasn't come up.
I've had lordosis for a while before I started lifting, squatting and deadlifting hurts my lower back and 2 weeks ago I was squatting 90kg and deadlifting 110kg, last training session I couldn't squat 80kg or deadlift 100kg without pain. In the book I saw a stretch that helps lower back but is there anything else you'd suggest?
Thanks
