Al Sears and PACE

Aerobics and other long-duration exercises like jogging and marathons create
changes in your body that weaken your heart and lungs. They tell you
body to make and store more fat. This way, your body makes sure it has
something to burn during your next aerobics class. And to cope with
long-duration stresses, your body will actually shrink your
heart and lungs.
Recent research on the PACE exercise invented by Dr Al Sears MD shows that it gives your body the right kind of challenge. And it only takes 10
minutes! Not hours of gruelling - not to mention boring -
jogging and jumping around that most fitness experts
tell you is the way to go.
