You pig. What did you think this post was about?
Anyway, most of us (let's be honest) are more interested in keeping our butts small than our hearts healthy. There's no denying, however, that a healthy heart is a wonderful "side effect" of working out.
Do you have to kill yourself in class in order to keep your ticker ticking? You'd think so, but you wouldn't necessarily be right. A new study says that heart health is more a function of exercise quantity than exercise intensity. So although "additional benefits" come from increasing intensity, working out more is better for your heart than working out harder.
Thanks to Dave "Whoah!" Feldman for the reference.
