Imagine my surprise when I was diagnosed with heart problems at the age of 36 shortly after completing the 2009 AIDS LifeCycle (SF to LA). My doctor discovered the condition by accident, but the consequences are real.During my recovery, I need to stay below my 80% of max heart rate when I exercise. Polar makes this easy. Thanks for this invaluable too.I hope to beat this soon and be back at 100%.
