There are three ways of training with weights:
Concentric work means actively overcoming an opposing force. For example, standing up in a squat with a barbell or curling a dumbbell.
Isometric work means bracing against a force and not giving up a single inch. In the same biceps curl, this is keeping the angle constantly at 90°.
Eccentric — this is slowly lowering the kettlebell while stretching the biceps. You yield to the superior force, but you control the process.
In the last case there is a chance not only to interact with what is bigger and stronger than you, spending less energy, but also to control it.
Interestingly, eccentric better stimulates muscle growth and strength increase. And besides, it teaches braking, when you need to soften a landing, stop your own movement or an opponent.
When what is said relates to sports, everything is logical. But if you transfer the metaphor to life, no one likes the third way.
Taking a moderate weight for many concentric reps — that’s fine. That’s your typical workday. Well yes, you get tired.
Isometrically withstanding the pressure of circumstances is harder, but also familiar. Grit your teeth, summon your willpower, and hold your ground.
t’s a different story when fate gives you a “gift” that is simply too heavy to lift. It’s obvious that your “defeat” is inevitable. Morally, this is the hardest of all.
But remember the benefits of eccentric in sports. If the goal is the development of your strength, there is no better way. It’s all about your attitude.
And most importantly, controlled resistance means that you are in close contact with the alien factor. And for example, in judo there is a whole section of techniques called sutemi-waza, 捨て身技 — sacrifice throws.
The idea is that you consciously follow the trajectory your opponent dreams of: you fall onto your back, taking him with you, seemingly submitting to his will.
But since the initiative is yours, you dose your resistance, directing the system of your bodies a little differently — where you need it to go.
Of course, for the opponent these are your most unexpected throws. And you spend less energy.
In form, it looks like your defeat. In essence, it is a victory.
Sincerely yours,

P.S. By the way, in ordinary language, “eccentric” means strange, non-standard, going beyond the accepted norm.
