Good morning friends, I've been a reader of the StrongFirst forums for a couple of years now and this is my first posting. As you can see by the title, I work at a desk for 8-12 hours a day and have for about 8 years now. I am 29 years old and feel that the time I have and continue to spend on my rump at a desk is getting the best of me. I have been progressing very well in my kettlebell journey up until about March of this year. I started to get nagging pains in my low back and have felt stiffness and limited mobility in my mid to upper back and my shoulders. This has been a frustrating bit of time for me just like it would be for anyone else - nobody likes to see progress come to an end due to joint pain or mobility issues. Plateaus I can break through - mobility questions is what has brought me here to the community. What I am looking for would be some simple mobility work I can do here at my desk to address these nagging pains. I do know that this will not fix my issue outright but I believe it could help with the yoga I do in the morning and my warm up before I train.
