I started jogging about 3 weeks ago....lately I have noticed that my muscles are very sore! Am I doing something wrong? Should I take a break for a couple of days? Thanks! (I jog about 5 times a week)

Are they your shins? Most runners, after not running for a while and then overenthusiastically running too much, develop shin splints. To prevent this muscle strain injury and other muscle injuries, stretch before a run (stretch usually where it hurts and slowly stretch further until the pain lessens), stretch after a run, sometimes stretch during a run, and stay hydrated!

I ran distance track in high school and run about 2x a week now.

I'm proud of you for jogging btw for new runners, it's hard to start

Muscle are probably sore due to small tears that are normal being repaired. Once running if the soreness goes away it's just the muscle being tight.

Thank you for your replies!! This has been very hard for me.... I HATEd HATED running....but now I am beggining to like it.. I have never done track or anything like that....but I used to be in ballet, jazz and some gymnastics when I was little...but I am 35 now....so that was a long, long time ago...
