I've been doing this, or similar intensity stuff for years really.
Usually 3 or 4.
I usually do my cardio on non lifting days so usually 24 hrs. I have increased my leg frequency actually, I've been doing 2 x week.
Yeah I understand this, and to be honest my running form probably sucks. I just like running really for keeping me lean (and stress-free!)
Just resting it really, physio said its just a strain. I have full ROM etc.
I feel totally fine, I WANT to exercise! I'm going to try again later and see how it goes.
Thanks for replying man.
