核心不只是腹肌, 是环绕躯干的一整个圆筒; 它的主职是稳住脊柱、传递力量, 不是练出六块腹肌; 六块腹肌是厨房里练出来的, 而核心专项训练也不比一般运动更能治腰痛

Resistance training basics
Core work obeys the same dose rules as the rest of strength training: quality you can hold rather than reps you cannot, adding a little time or load each week. Progressive overload does not change its principles because the target is the trunk.

What the core is

核心是什么 · 一个圆筒, 不是一块腹肌

In plain words first: many people think core = abs = the six-pack, and grind out crunches chasing a 'flat stomach'. That's a misunderstanding. The core means the entire ring of muscles wrapping the middle of your trunk — like a cylinder (or a soda can), from the bottom of the ribcage down to the pelvis. The site is the whole mid-trunk, not just the front layer of the belly.

Its real job is two things, neither of which is 'growing a six-pack':

1. Stabilise the spine: so that when you bend to lift, get shoved, or stand on one leg, the spine doesn't wobble or collapse. It's more like the guy-wires around a mast than an engine that produces movement
2. Transmit force: when you run, jump, throw, or lift, force is generated at the ground through the legs and hips and must pass through the trunk to reach the arms or an opponent. If the middle is soft, force leaks out; only if the middle is stiff does force transmit efficiently

In other words, the core's real role is to be a solid bridge that lets force cross efficiently from the lower body to the upper (McGill 2010). The rectus abdominis (the six-pack) is just a small part of the front wall of this cylinder — and how visible it is depends mainly on your body fat, not on how many crunches you did.

The first intuition this island builds: training the core trains stability and force transmission, not sculpting abs. Separate those two ideas and every myth ahead becomes easy to dismantle.
