oh, wow! You have condensed into 9 minutes just about everything that I have learned over the past 45 years! Thank you so much for putting this together and sharing it. :)

Helpful, easy and clear explanation - making me realize why and how my running posture was far from optimal (and definitely contributed to my runners knee). Looking forward to get back into the game with proper form!

This was super helpful! Thank you, Katelyn!!

Side or towards midline is fine for distance as long us you don’t unlock the elbow. For sprinters it’s more vital or the faster you go to be straight and back…

Another one to go with the arms is not to clench tour hands in a fist. I’m a beginner to running, trying a couch to 5k, however that is one tip I learned years ago.

Hi! Now during my off season I’m running three days a week and doing two weekly strength training sessions (3+2). I’m not sure whether I will run 4 or 5 days a week during my marathon training. What are your thoughts of incorporating strength training into marathon training schedule? Is it better to have a 4+2 ( 5+1, in case of 5 running days) schedule or is it better to lift on running days (after running) in order to have additional rest days? I would prefer 4+2 or 5+1 approach, but then I will have fewer rest days, right? I would really appreciate your answer. Thanks a lot! Btw, I was heavily overtrained for two years a couple of years ago. Since my complete recovery, I have already run some relatively successful races, but I am paying my attention to the intensity of my training (before overtraining I always thought that training more is always better, not sure about that now).
