Stupid question. Of course you are!
Nobody wants to go after their goals, only to have their body let them down.
When I speak to athletes, we usually get around to why they started sport in the first place.
Everybody has a slightly different answer, but the vast majority come down to this: "I wanted to lose weight, I wanted to look better naked or I had a health scare and my doctor told me I needed to do some exercise. This sport felt like it would be a great way to do it without just running on a treadmill."
But the story goes on from there. Most of us have forgotten why we started.
We've got tied up in the world of performance. It's a world where going faster or lifting more by almost any means is the goal. It's a world of better equipment, more "ergogenic" supplements, more data and looking for that extra bit of workout time.
Sadly, this pursuit of performance means that so many of us have simply accepted injury and illness as "the cost of doing business". It's rare to find a long term athlete who doesn't have a long-term injury or some kind of recurring illness.
It really doesn't have to be this way.
