Keeping fit....well do ya?

[galaxy xr8]

Well I'm trying to put weight on,but it's not happening because with my new job I've lost 10kg because I walk 20+ klm's a day in my job 5 day's a week and then when I get home my girlfriend want's to take the dog's for a walk so we do that and then I train with weight's 3 time's a week, it's got to the stage where I just can't sit down anymore because I get bored and need to do something, so my body tell's me, and now my girlfriend and I are looking into getting some mountain bike's to go for a ride after work, this will be the death of me,lol.
