I went to a gym this spring, since I got a discount at the universitys gym. Went there 2-3 times a week.
Membership ended a month ago, I have not worked out since. I play football with mates twice a week. My stamina is at its bottom, it has never been this low before. Which kind of sucks, but running is so incredibly boring, I can't see me ever taking that up.
Solution? More football!
