One of my favourite movies was on a few weeks back - "Unbreakable" with Bruce Willis and Samuel L Jackson.

In it, Sammy L plays a guy who has a rare genetic condition that gives him very brittle bones that has led to a lifetime of breakage. The nickname "Mr Glass" has stuck with him since childhood.

I'm guessing that nobody would choose to be born with such a condition.

Changing subject for a second, a gym-going friend of a friend of mine tore his quad before a friendly football kickabout the other day taking a warm-up shot. This guy does plenty of gym work, is what most most consider "fit" but hasn't played for a while.

I remember a very similar incident years ago, playing a friendly game with a personal trainer who pulled his hamstring not long into our game making some innocuous movement that didn't look like it would blow out a hammy.

We wouldn't choose to be born "made of glass" but most of us unknowingly turn ourselves into glass through our training.

I train in a commercial gym at the moment and most of the members are making themselves more and more fragile with their training.

Think of how many angles, directions and shapes a person can move in. Cast your mind to gymnastics, dance, yoga, martial arts and parkour for examples aplenty. Yet most people's training has them exclusively perform a few movements.

To put it simply, they become strong at these and weak in all the others.

A quad that has only seen squats and leg extensions for a while isn't well prepared for kicking where the hip goes into rapid extension as the knee does.

A hamstring that has only been challenged by leg curls and deadlifts doesn't know how to cope with eccentric loading at high speed when the upper body is twisting as well as hinging.

Most people's training eventually leads to them "shattering".

Don't be most people. Train many, angles, shapes and movements.

Become less "Mr Glass" and more unbreakable.
