For about 4 months straight, I'd start my treadmill run at 6:15 AM and always bail by the 10 minute mark to grab a smoothie and sit on my phone, and this older regular named Dan finally walked over and said, 'You know, you sweat more from the decision to start than from the running itself.' He didn't push me or offer a plan, just pointed at my habit of shutting down right when the discomfort kicked in, which was way more accurate than any app or chart I'd tried. Has anyone else had a stranger call out their exact quitting trigger without even asking?
