Workout Wednesday
Go walking and walk as many steps as you can on an exhale hold.
Improve your ability to take more steps on an exhale hold over time.
You are improving your carbon dioxide tolerance, your ability to respond to stress, and your overall cardiovascular and respiratory endurance.
Keep working on this over time to free yourself from anxiety, sleep apnea, shortness of breath/chest breathing, (exercise-induced) asthma, and other (expensive) band-aids thought to solve those problems.
This is free and simple to follow. It just takes a little consistent effort and a willingness to change by feeling a little uncomfortable sometimes.
