I walk and exercise my dogs for up to 2-3 hours a day, when it's nice out I go hiking and mountain climbing (also with my dogs), and I ride BMX and go mountain biking. I also skateboard and snowboard occasionally. In the summer I go swimming and kayaking. I am a very active and outdoorsy person.
I want to invest in a dirt bike too but I don't think that counts as exercise because it has a motor.
The gym is my worst nightmare, I prefer to exercise outdoors.
