Exercising doesn’t have to be expensive

Lifestyle-Fitness-Gear-for-release-620x330.jpg

2016 has been the year of the smart watch for me. I got an Apple Watch sports (~$400) and then got two GPS sports watches (more than $1k total). That’s a lot of expensive watches in the same year!

I already wrote a review of the Apple Watch and then made a complete guide of GPS sports watches. Go read them if you haven’t yet!

Let me be clear though: if sports watches help you train, you don’t need a GPS sports watch to exercise. Actually you really don’t need any expensive gear to exercise and have fun.

The Art of Relaxation

I first encountered the paradox of relaxation in years of martial arts training:

The more relaxed you are, the faster you will be

If I come to a kung-fu class tensed, I would inevitably get my ass kicked @#$$!

However, if I am relaxed, I am able to have a higher reaction time, discern attacks and be able counter-attack with speed.

This is counter-intuitive. Instinctively, our muscles and body tense when face to danger. Why should we learn to be relaxed instead?

Good Stress and Bad Stress, Part II

The previous post laid out the history of stress, explained how stress imposes a reaction, and the difference between good stress and bad stress.

In all activities, there is always a ceiling. It can be genetical and limit maximum strength, speed, coordination in physical performance. It can be environmental or geographical. Where we live and study determines for example the quality and scope of work. It can be a time ceiling, giving us limited time to accomplish required tasks.

This maximum can be attainable after a long and hard journey and is illustrated by the red line in the graph below.

Good stress and Bad stress, Part I

History of Stress

The term stress was borrowed from physics by the first stress researcher Hans Selye.  In physics, stress describes the force that produces strain on a physical body (i.e.: bending a piece of metal until it snaps occurs because of the force, or stress, exerted on it).

Hans Selye noticed that all his patients, regardless of disease, all looked under duress. He decided to name “stress”.

Saying No To Passive Entertainment

How do you make everything happen? There’s work, money, friends and family, exercise, nutrition, sleep. So much to do, so little time.

My advice would be to drastically cut passive entertainment.

This is when you undertake an activity with little physical and mental activity. This goes from TV, Netflix, Youtube, social media to video games and drugs etc.

Managing Your Physical Condition with Heart Rate Variability

hrv_300

In a previous post, resting heart rate was shown to reflect physical and mental condition. A low resting heart rate correlates with good health compared to a high resting heart rate.

It becomes complex when you consider age. Older people have lower resting heart rate. And individuals with the same age, nutrition and overall fitness level can have vastly different heart rates. For instance, my maximum heart rate when running is around 172bpm while a friend has 200bpm, with the same heart rate sensor. It does not mean however that I am more or less fit than others.

Avoiding the Modern Plague of Noise Pollution

Noisy aircraft and highway traffic. What could happen?

Noise pollution characterizes modern society: busy highways and railroads, bad commute traffic, aggressive motorists, construction, manufacturing plants, loud TVs, vacuum cleaners and neighbours. These are numerous, pervasive, persistent and socially significant.

You probably know about the ill-effects of processed food, lack of exercise, mental fatigue, but have you thought about the long-term consequences of noise pollution?

Recent studies show the health effects:
