Actually not too bad, considering I’v just played competetive sport for the first time in years. A game of 4 a side footie in the gym at lunchtime for about 45 minutes. The problem isn’t so much aches and pains, but my lungs had no capacity, and I got short of breath early on. That, and I was crap.
If any one knows a way to improve lung capacity then let me know!
