Now I’m a big fan of the recumbent bike.
Bike a sprint, then lower the rate.
You want some stress, some sweat.
Along with fewer nighttime snacks,
watch the carbohydrates.

Yes, you can mix walking and jogging.
If you feel tightness in the chest,
stop. But, for most of us,

running runs its course. The heart stiffens.
Normal circulation never returns.
The heart doesn’t relax.
