Here's a question that makes my brain cook...
I recently started swimming again after a long layoff, combining swimming with other forms of aerobic exercise. Given my age, my target heart rate should be around 141-155. Yet when I swim at the pace I think I should go and check my pulse, it's always over 160. I don't feel chest pains or anything, and swimming slower feels next to impossible (not that I'm that speedy these days, anyway).
How much should I be concerned about this? Will my heart rate drop as I get in better shape?
