Being stronger is better. Period. Anybody that tells you otherwise, doesn’t know anything about being strong or about being better. Strength is not just how hard you contract your muscles nor is it how big your muscles are. Strength is the productive application of force. Strength is force applied at the right place and at the right time to complete a task. If you cannot complete the task, then you are not strong enough. No amount of stepping on the pedal or turning the wheel will make your car go forward if there is no engine under the hood. The bigger the engine the faster the car goes. There is no real world situation where strength is a disadvantage. It’s not the only important thing but you should never pass up an opportunity to get stronger and avoid people that encourage you to do so as they are not to be trusted.
Jiujitsu guys love to give lip service to technique. And you see guys complain when they get tapped that the other guy was using too much strength and their technique was bad. A tap is a tap. In the real world we don’t tap just because someone used good technique. We tap because the move worked. Technique is merely the movements or positions used to accomplish a task. There are many many different techniques that can be used to accomplish the same task. When we rate a technique as good or bad what we are really looking at is the amount of energy expended to accomplish the same task. One technique is “better” than the other if it accomplishes the same task with less energy. Both good and bad techniques can be effective and accomplish the task, but the more efficient technique will lead to better results in the long run.
I want you to have strength and technique because both of these vectors point in the same direction. We have all faced the person who has limited technical ability but they make up for it with a lot of strength and they are tough opponents and can overcome very advanced practitioners just based on their size and strength. We have also faced some tiny black belt that seems very frail yet they are able to gradually break down our defenses and submit us. However, the most formidable opponents are the ones that are strong and technical.
To separate strength from technique is actually a fallacy and cannot be done. Strength and technique both point toward task accomplishment, i.e. getting the job done. An athlete that has good technique will appear stronger because the techniques they use will maximize the force they can apply to an opponent. Conversely, a stronger athlete can overcome technical deficiencies with their strength and pull off moves that a weaker athlete would not be able to.
Choose strength and use that strength to bolster your techniques.
