I'm 38, 6-1, 215lbs. I work as a hands on General Contractor, do heavy off road dirt bike riding on the weekends. I run a little bit, but nothing to brag about. My problem is I stiffen up. At lunch time, after work (just the ride home and I am rigid!). Morning stiffness is horrible. No real joint pain, just my whole body. What gives? I feel like an old geezer! Any suggestions?
