Hello, I'm new. I'm working my way through the Bupa beginner half marathon plan (finished week 2 this morning ) and have a cross training day coming up in a week or 2. My friends say they go to the gym on that day but I don't want to join, for financial reasons amongst others.
I feel like I should be doing more to improve my overall strength and flexibility.
So I guess I'm after suggestions/links to decent cross-training routines/videos to be done at home for running that they would recommend for a beginner like me looking to build strength and increase flexibility?
