From several years' PMs, I know the Cardiac Club around here is bigger than we would like, except that AFAIK (from the limited numbers I know), the members are still kicking.
Now I'm a member.
Any who care to share the BEST things that got them back on the upswing? Diagnoses only if desired....
I'll start:
1. It takes longer if you don't start. 2. Aquatics done VERTICALLY do the heart (and esp. BP) MUCH more good than swimming/being horizontal in the water, plus hold heart rates down to "reasonable" while still giving a training effect.
