I like running and run 3 times a week. I sometimes chuck in a bit of yoga. I think I need to add in some strength work. My arms are feeble and my core could do with some work.
I have no idea how much strength to do without risking injury and being able to fit it into a busy life. I was guessing, keep up my running, strength two days a week and yoga once a week. Does this sound about right please?
