Will medium intensity bodyweight exercises beetween hard running days hurt the recovery process?
Would it be better to do them on the hard days? Or better dont do them at all?
This is for runners training 7 days pr week, with hard intervalls 3 days pr week.
This is just an example of exercises I am referring to
