Great...was training on my own today on the heavy bag; at the end did another set of knee kick drills...and got a super nasty stress fracture of my right foot. It's absolutely ****ed.
I'll be in plaster for the best part of two months; but with luck I won't need an op to plate it.
That's totally stuffed my training though. And I shall have to completely re-think how I train in the future; although in fairness it could have just as easily happened while running, lifting something heavy, or jumping off a kerb.
