As a guy who had his hip / leg give out carrying some heavy weight upstairs I would consult with your doctor to be certain. I used to run in the winter months for 5 times a week at 45 minutes on a treadmill and get my exercise in the good weather with long walks with my dog. I had to give up running until I am told my hips can withstand the pounding, I applaud your exercise routine by the way.
