Workout in the wild
Exercise makes you happier and healthier (and so does nature!!) combine the two and take your jog through a local park or reserve.
Change your walking, jogging or cycling route to exercise in wild places, and watch your stamina and motivation improve (as if by magic!).
Rather than going to the gym, you could even workout by volunteering for a couple of hours on a nature reserve: it’s social and fun and you’ll burn those calories, too!
