Exercise transformation with training: went from barely able to walk a block to completing a 10K last weekend.

Gym confidence after training weight loss: walked into a gym for the first time in 10 years yesterday. Was terrified. But you know what? Nobody stared. Nobody judged. Everyone was focused on their own workout.

Started with 20 minutes on the treadmill and some machine-based resistance exercises. Nothing fancy. But I DID IT. And I'll go back tomorrow.

To anyone too intimidated to start: the hardest rep is walking through the door. Everything after that is just movement. 💪

One concrete data point for the thread. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

Coming at Dr.CardioMD’s question from a different direction. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

A narrower follow-up, since the general answer is now clear:

Was that from a primary source or from a summary of one?

Reporting back.

For the archive: it took about six weeks rather than the two I expected, and the difference between those two numbers was the whole of my problem.
