Re: Calf Strain while POSE running
Sore and tight does not mean a strain.
Do some massage -- myofascial release & cross friction on the areas -- as well as stretching/tennis ball/foam rolling. Should help loosen it up.
Try *not* to do high volume work while learning POSE or any other new techniques. You're working muscles with new movement patterns so they're not used to the stress. Lots of running while doing POSE often messes people's calves up. Your problem is nothing new, and it can easily be avoided.
