Conclusion

Yes, I did improve the health of my heart by doing more exercise. After seven weeks of training, my heart rate at the end of climbing and descending 140 steps was only 127 compared with 160 before training.

The heart is one of your most important muscles. To keep it in good shape, you have to be very careful. Or else you can suffer greatly later in life. So, to have a long and prosperous life - stop smoking, eat a healthy diet, take lots of exercise, and most importantly, start today!
