Muscle size, strength, aerobic capacity, flexibility, physique and physical health are the obvious perks of exercise and training. But is that it? Looking for additional reasons to exercise?

Research shows that most people who exercise regularly do so because of the enormous sense of well-being that comes with different form of activity, ranging from a 20-minute sprint to heavy lifting. So how does science explain this feeling of joy and euphoria?

One thing’s for sure about endorphins: their ability to make you feel so,so good. When the body is subjected to certain stimuli like sex, food or pain, the hypothalamus (the command and control centre of our endocrine system) calls for endorphins. The cells throughout the body that contain them make sure they hear the call. When endorphins lock into specialised receptor cells (called opioid receptors), they block the transmission of pain signals and also produce a euphoric feeling -exactly like opiates.

Ever hear of the runners high??? Well, it really exists; and the reason behind it: endorphins.

Heavy weights or training that incorporate sprinting or other anaerobic exercise produce our happy chemical!

When our body crosses over from an aerobic state to an anaerobic state, it's suddenly operating without enough oxygen to satisfy the muscles and cells screaming out for it. This is when the runner's high occurs.
