A new study conducted by Harvard researchers showed that as little as 150 minutes (2.5 hours) of exercise a week can dramatically cut heart disease risk. For those who did more, about 300 minutes a week (five hours), their reduced risk of heart disease, including heart attacks, angina and bypass surgeries, increased to 20 percent compared to people who did no exercise, the study found. Researchers also noticed a significant gender difference in results - which showed while exercise resulted in a 22 percent reduction in heart disease risk among men, it increased to a 33 percent reduction among women.
"The overall findings of the study corroborate federal guidelines - even a little bit of exercise is good, but more is better," Dr. Jacob Sattelmair, an epidemiologist at the Harvard School of Public Health, said in a written statement.
So take a quick walk. Do some gardening. Play a game of tennis or go dancing. If you have the time and energy, tie up those gym shoes and go jog, swim laps, hike or take a fitness class. It helps the heart!
