I’m a better dad, husband and colleague when I exercise. So although it uses time that I can’t get back (which others might argue could be better spent), for me and those I’m with, it’s a good investment.

In real terms, let’s say we’re talking about 1 hour of exercise plus a shower and food. It’s an hour and a half out of about 16 each day – that’s 9%, which in turn makes the 91% more productive or of higher quality.

There are times when that 9% of time takes more than 9% of my energy – so perhaps later in the day I still have time, but I’m starting to flag. Knowing that, I look to apply a balance where that’s not the case every day, perhaps just once or twice a week if I’m trying to make physical progress in training.

To flip it, everyone also benefits if let’s say your partner is happy. For that to be the case, perhaps they need to go out with friends a few times a week. Granted that’s time, energy and money away from you, but if when you’re together it’s better, then there’s a case to say that’s worth it.
