My favourite hobby is muay thai kick boxing, and we spend lots of time conditioning our shins ,thighs and forearms to take big impact blows. When it comes to sparring and fighting, it really does make a difference, albeit of no use anywhere else.
If you get out there the brain and nerve will re-calibrate your balance, and lead to less skids and falls.
In Poland we will cover some long distances, and unless everything is good, from rucksack straps to boot lces you will start the day off feeling a little bit creaky.
Over the years I have found that there is no way of conditioning for long days out in thick snow, until the last UK big snow fall. I saw ankle weights for sale for £1.00 at a supermarket. Perfect, on they went and they were on every time I went out for a walk. They worked a treat, and no hip fatigue when we were out tracking( and coming back along what trackers call the long road home)
