Gym confidence after training weight loss: walked into a gym for the first time in 10 years yesterday.

Pet owner bonus of training: my dog is also losing weight because we're walking 2-3x more than before. His vet is thrilled. 🐕

We went from a 5-minute shuffle around the block to 30-minute walks through the neighborhood. He's more energetic, I'm more energetic, and we're both healthier.

Get a dog. Or borrow one. Walking a dog is the best low-impact exercise motivation that exists. They never let you skip a walk. 🐾

One concrete data point for the thread. For anyone reading later: the numbers in this thread are worth checking against a primary source before you act on them, including mine. Half the figures circulating in this community trace back to a secondary summary that dropped a qualifier.

Adding the part of the answer the thread has not reached. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

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

What did you change at the same time, and can you separate the two now?

Closing the loop on my own question.

Late follow-up. I did not do what was suggested, I did something adjacent, and it worked; posting the difference in case it matters to somebody.
