Continual Effort
Easy walking provides aerobic exercise, which means the whole body becomes oxygenated. Aerobic exercise counters diseases that thrive in the absence of oxygen, and it promotes the body’s fat-burning metabolism. Soft aerobic exercise can be continued almost perpetually.
On the flip side, strenuous activity calls for frequent rest breaks. Fast uphill climbing, with bursts of effort and heavy breathing, represents anaerobic exercise. Lacking oxygen, the body triggers its sugar-burning metabolism. Too much anaerobic training wears you down.
While the body burns both fat and sugar all the time, you can train in the aerobic state, getting both stronger and healthier in the process. Thus, advanced training coordinates bursts of effort with continual effort.
