Dont know if this is a dumb question or not.
About 5 months ago I started getting really serious about working out and have developed upper body strength quickly, my knees and thighs have been hurting lately and I find myself stretching them out all the time to work out the kinks or whatever. Maybe its the winter cold doing it, im not too sure. Perhaps this is a sign I need to start working out my legs more?
Thanks.
