Triathalon Training

Will training for a triathalon make you a better cyclist? World-class triathletes are slower runners, swimmers and cyclists than athletes who compete in only one sport.

Advertisements on television claim that you can wrap a special belt around your belly, plug it into an electric outlet, turn on the electricity, and then watch your belly muscles contract to give you rock-hard belly muscles.

The more frequently people exercise, the less likely they are to die of heart disease (JACC Cardiovasc Imaging, 2017;10:1461-1468), but there is some evidence that a person can increase heart attack risk by exercising...
