mind muscle connection

<think> The user wants a 1-paragraph executive summary synthesizing 5 atoms about "mind-muscle connection." Let me analyze what the atoms collectively say:

1. Arnold Press - Full rotation matters; the specific movement path creates the unique stimulus
2. Face Pulls - Scapular retraction first, then arms (10x muscle recruitment)
3. Face Pulls without back engagement = cable bicep curl
4. Nervous system, not muscle tissue, caps performance - arousal can unlock more reps
5. Pull-ups - both ends of range of motion (stretch and contraction) drive growth

Common thread: in each case, people are going through motions without actually engaging the target muscle. The "mind-muscle connection" is about deliberate internal focus on the target muscle's role in the movement - whether that's rotating to stretch the front delt, retracting scapulae to engage the back, hitting the full ROM for stretch-mediated growth, or pushing arousal to override neural inhibition.

The atoms collectively argue that the mind-muscle connection isn't mystical - it's the deliberate internal cueing that determines whether a muscle actually does its job. Without it, you're just moving weight through space rather than loading the target tissue.

Let me draft a 3-5 sentence paragraph in present-tense, plain English:

Draft 1: The mind-muscle connection is the deliberate internal focus that determines whether an exercise actually loads its target tissue or merely moves weight through space. Across movements as different as the Arnold press, face pulls, and pull-ups, the pattern is the same: people perform the motion but skip the specific muscle action that gives the exercise its purpose — the 90° rotation that stretches the front delt, the scapular retraction that recruits the upper back, or the dead-hang stretch that drives hypertrophy. Even raw strength output is governed less by muscle size than by nervous system engagement, meaning arousal and intent can push performance well past what feels like failure. In short, the difference between an exercise and a muscle-building movement is almost always a matter of paying conscious attention to what the target tissue is supposed to be doing at each phase of the rep.

That's 4 sentences. Let me check it flows and synthesizes without enumerating. Good - it mentions examples but weaves them into a synthesis rather than listing them.

Actually, let me refine to make it tighter and ensure plain English present-tense voice throughout.
