I run 5 days a week, and normally on my 2 days off my gf gets me doing something equally intense like hiking, kayaking or rock climbing. I do between 100-150 pushups a day and other bits of exercise here and there. I’m the fittest I’ve ever been, honestly. When I’m done travelling I’d like to take up some form of self defence, so I at least know how to throw a punch or whatever.
