In this episode, Herb explains how many runners over 50 slow down due to aerobic deficiency syndrome (ADS), caused by overreliance on anaerobic training that burns sugar and produces lactic acid, leading to pain, fatigue, and plateaus. He contrasts this with the aerobic system, which is fueled by fat, has no byproducts, and can burn lactic acid. Herb shares his own experience discovering his “easy” runs were at 135–145 bpm and offers a simple self-test: if a comfortable run averages under 130 bpm, aerobic fitness is likely decent; consistently above 130 bpm suggests ADS. The fix is months of running at or below maximum aerobic heart rate, estimated by the Maffetone formula (180 minus age) or personalized by avoiding late-run heart-rate drift. He invites viewers to join his free Forever Running Club and comment about their easy-run heart rate.
