Hi i have a constant ache in my lower back which developed about a month ago. It isn't too bad but a little annoying, i know i haven't injured it so am wondering why. I feel that it's possibly
1) Not doing enough deadlifts as it effects an injury in my upper back. If you agree then do you have an alternative that won't affect the upper back so much.
2) Rapid increase in weight. I have upped my calories and the weight is going up fast.
Any advice much appreciated
