There is good news for those who have been avoiding exercise because they believed they didn’t have enough time. A new study shows that as little as 10 minutes a day can improve our cardiovascular health.

The research found that people who have been really sedentary and started exercising an average of 72 minutes a week noticed the difference almost immediately. All they had to do is get off the couch.
The intensity of exercise the women in the study engaged was very low almost equivalent to walking at a speed of about 2 to 3 miles an hour.
The researchers also found that while a little bit of exercise was beneficial, more exercise boosted cardio-respiratory health even more.

The goal of this study was to determine how much exercise we need to see a benefit and to see if more exercise would continue to produce additional benefits? They included 464 postmenopausal women who were considered overweight or obese and who suffered from hypertension. They were randomly assigned to four groups: the control group that remained sedentary; a light exercise group that averaged 72 minutes a week of exercise; a moderate exercise group that averaged about 136 minutes a week; and a high exercise group that completed nearly 192 minutes of exercise each week.

The study showed that the women in the light exercise group increased their peak oxygen consumption levels by 4.2%, the moderate exercise group saw a 6 % rise and the heavy exercise group upped their cardiorespiratory fitness by 8.2 %.

The study clearly gives evidence that with a little bit of doable dose of physical activity, a significant improvement in physical fitness is inevitable.
