total novice here! always hated sport/ PE at school nut fee i need to do something. I'm 35, weigh about a stone more than I'd like but the icing on the cake is having my blood pressure taken last week and it being way too high. So I want to do something positive. However...I don't even own a pair of trainers. What kit do I need to run exactly? If someone can give me a beginner's shopping list, that would be great.
