Technique is everything:

This may not be news to most but when it comes to exercise, technique is everything.

I used to not pay too much attention to this. My approach was to perform an exercise by meeting its general criteria and increasing the number of repetitions over time.

Squat? Lower my upper body while keeping my heels on the floor, done.

Downward facing dog? Hands on the floor, feet on the floor, lift the hips and try to approach the floor with the heels, done.

Rowing? Just pull the oar towards you and push it away by using both legs and arms, done.

Over time I realized there is much more to every exercise I’m engaging in. In fact there is a whole internal landscape to be explored. Small feelings and sensations that deserve attention and that can make all the difference when it comes to performing an exercise efficiently and safely.

An exercise not done with the correct technique is an exercise not worth doing. In fact, it may be counterproductive in the long run as bad habits eventually accumulate and cause injuries.
