A study by the University of São Paulo discovered that “aerobic training facilitates the removal of dysfunctional mitochondria from heart cells”.
What does that mean, exactly? Basically when you exercise you’re removing the bad mitochondria, which are responsible for providing energy to the cells. This reduces the production of toxic molecules, such as oxygen free radicals, an excess of which damages the cell structure!

Human beings evolved to move. Our bodies, including our brains, were fine-tuned for endurance activities from our history as hunter-gatherers. There is consistent findings that the brain works better after exercise, but discovering why has been more difficult.
Exercise changes both the number of neurons in your brain and how they communicate, as well as becoming more sensitive to the world around us. It has been suggested through studies that if the brain isn’t challenged or stressed enough it may reduce capacity to save energy as a response to inactivity. Read more in these two articles:
The pectorals are the largest chest muscles, and they tend to be tight on almost everyone, especially if you spend long hours at a computer. This stretch can give you relief from upper back & neck pain, which are often sore due to the opposing pull of the pecs. Simply position yourself in an open doorway, with your elbows bent to 90′ and at shoulder height, so that your forearms are resting along the frame with hands pointed toward the ceiling. You can choose to stretch both sides at once, or relax one arm at a time . Step ahead and lean through the door, keeping your arms in place, until you feel a comfortable stretch across the chest. Hold the stretch for at least 30 seconds or until a release is felt.
To enhance the stretch by targeting the slightly different fibre directions of the large pectoral muscles, repeat the stretch with your hands 1) lower, just above shoulder height on the door frame and 2) above your head on the door frame, high enough that your elbows are only slightly bent.
An absolute must for runners and lovers of high-heels. Stand with feet at hip width. While the leg you want to stretch stays in place, take a large step forward with the opposite leg, bending the knee so that it is directly above the ankle. Lower the back leg so the knee comes toward the ground, increasing the stretch across the front of the hip and thigh. Keep your torso straight and your tailbone tucked, so that your hands or arms are resting on your forward leg.
