As a soldier I used to work out a lot, plus the job naturally kept you fit and in shape. Although I wasn't big I did a lot of running and endurance work via pack marching and carrying big weight. Used to run the odd marathon or two.
Once I left the army I let myself go, plus getting older dosn't help.
It's time to get back into shape, especially after taking some photos of myself.

Stay healthy, live a good life, burn off stress, seeing progress.
