There are a multitude of attributes that need to be highlighted to increase the quality and longevity of physical strength. Mobility, breathing, technique, most of which deal with proprioception or awareness of what is happening. Being mindful of each repetition as it passes to the next incorporates a large chunk, diet making up most of the rest. 

It is setting the intention to evaluate performance instantaneously, during a training session. Stressing the importance that every rep counts. From the fault of a less than optimal rep we learn how to correct before repeating. During moments of being in the “zone” we see what is achievable and how well we can/should move. Practicing mindful repetition correlates into all areas of life and will become second hand in competition. 

It is not only due to the time under tension that strength increases, but the storing of movement patterns. Inappropriate firing along the kinetic chain will always trump sheer size of muscles. Placing a lot of force close to the right direction can get the job done, but is usually done by compensation. Meaning that if we want to continue to move outside of the optimal pattern, something will have to pick up the slack even if that is not its intended use. Building the illusion of strength for it is on shaky foundations. 

There is a place and time for the brain to “shut off”, letting the body take over and do what it is naturally meant to do. This has to be trained or at least maintained, for years of repeated poor posture or bad form will eventually catch up. Asking the question “do I truly have control through each entire repetition, especially when it really counts”. Quality movement is a long term solution, quantity has its importance, but is dependent on the percentage of quality.
