Gym confidence after training weight loss: walked into a gym for the first time in 12 years yesterday.

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

My fitness journey alongside GLP-1 therapy:

• Month 1-2: Walking 15 min/day
• Month 3-4: Walking 30-45 min, started bodyweight exercises
• Month 5-6: Joined a gym, started resistance training
• Month 7+: Running, lifting heavy, swimming for fun

The weight loss made movement possible. The movement made more weight loss possible. Virtuous cycle in action.

The figures, for anyone assembling their own picture. Say what you would expect to see if you were wrong, before you look. It is a small discipline and it changes what you notice.

Coming at Dr.SportsMedIN’s question from a different direction. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.

One thing that is still open after sophie_paris’s answer:

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

Closing the loop on my own question.

Closing this out. What actually changed my mind was the point about waiting for a trend instead of reading a single measurement, which is embarrassing in hindsight and worth saying anyway.
