I've decided against it. Basically, my money should be going towards stuff that helps for sure. I know that cardio exercise helps anxiety for sure. It is a given. Mindfulness - I will try free YT, but that is a maybe. So a bike - turning the commute into an exercise - is a justified expense. Workout clothes - I do not go to the gym often enough simply because I have to wait for the wash day - are a justified expense. Even an HRM, although it sounds gadgety and thus suspect, is justified: without it, on the treadmill, I hold the sensor handles and that reduces caloric expenditure (you burn more calories if you move your arms while walking/running) and makes for a weird gait. I want my heart rate to be read by the machine without holding the handles. I know that the higher the HR, the less anxiety I will have.

I will make the most out of this surefire method before trying new modalities.
