Every ride starts the same way. You pull the bike off the rack — something you have done ten thousand times. It is automatic now.
But that small moment is a choice. And whether it still feels like one tells you almost everything about whether your training is adding years to your life or quietly taking them.
So let me ask the uncomfortable question first. You are committed — that part is obvious, and it is a good thing. But have you ever quietly wondered if it has tipped into something else? Whether you have crossed from committed into addicted? That word lands differently, because we all know addiction is bad.
Here is the truth most people never stop to consider: there is a fine line between the two. This week I want to help you find it — so you can decide for yourself which side you are on.
First, the bright side
Start here, because it is the whole reason this matters. Committed training is one of the most powerful tools we have for aging well. The link between regular activity and lower all-cause and cardiovascular mortality is among the most consistent findings in all of medicine. It protects the brain. It defends the muscle and bone the years try to take back. This is not an argument to do less. It is an argument to protect something valuable.
Where the line actually is
The line is simpler than the headlines make it. It is not your hours, your intensity, or how much you love the sport. Researchers put it in one place: autonomy — whether the training is still self-determined. Which comes down to a single question. When you reach for the bike, are you still the one choosing?
Three quick tests tell you. Here they are — plus a one-page version you can print and keep.
