At the Cave, we are constantly tweaking technique in our training.
Athletes with solid technique will lift more and with less chance of injury.
We have all seen very strong people with lousy technique who can move big weights, at least in the short run of things, but it will eventually catch them.
Maintaining correct form from the beginning is the best and safest way to train.
Does that mean you will never get injured?
No, it just means you will reduce the risk of it.
The same thing goes for a clean lifestyle, including good nutrition, regular exercise, plenty of sleep, etc.
This does not make you bullet-proof against sickness, however, it reduces the chances of it.
One day for no apparent reason you might get blind-sided by an injury or medical challenge. You can be doing all the right things and still get whacked.
If it happens to you, do not get discouraged or just give up.
Be grateful you are still alive and learn from it. Make whatever changes are necessary to improve your situation, then be consistent in it and patiently work through the process.
You have been given the gift of a second chance and you are blessed. Never quit!
