My usual exercise is using a stationary bike, but I've been having a sore hip/knee on one side for awhile (I used to run but it would turn into a sharp pain that left me limping, so my doctor told me to just avoid running since it puts too much pressure on that area). After reading around, I got a foam roller since I read that it can help with that type of pain but I'm not really sure which exercises I should be doing since there are tons of options on youtube and other sites and it's a bit overwhelming.
Can anyone give me some links (preferably with video) to which exercises would be the best to help with a sore hip/knee from bike riding and/or running? Also, how long should I be doing these exercises and are they only post-workout or both pre/post?
Any help/advice is appreciated, thanks
