Training Plateau: How Would AI Explain It?

Author:Jeremy Fix Original

A quick log from recent pull-up and push-up training

Event: I’ve hit a clear plateau on pull-ups, and I’m curious about the underlying mechanism
Keywords: training, body mechanics, pull-ups, push-ups

I’m not an athlete. I’m 36. I’m writing this down because I want the next six months to be guided by a more scientific understanding (and practice), rather than brute forcing.

Recently, I’ve been stuck at 6 pull-ups. This number has held for a long time. What’s most striking isn’t just fatigue at rep 6. Sometimes I’m standing under the bar, I grab it, and in that instant I feel a strong pull of retreat—like there’s no power to initiate the first rep. It feels like my body isn’t ready.

When I reach my “limit,” the experience looks like this: my arms start to hurt; my shoulders and chest can’t support another rep. My body pushes back hard, as if it’s telling my brain, “No. Absolutely not.” And yet subjectively I still feel like I have more in the tank—like my potential is higher than this.

I also notice a similar pattern with push-ups. I usually count while doing them: a set is often 30 reps. After a 5-minute rest, I can often do another 30. But 30 still feels like my ceiling. The set tends to go like this: the first few reps feel challenging and less stable on the way down; after the first ~5 reps, it becomes smoother up to the 20s; then it turns difficult, and I grind my way to 30.

What’s interesting is that I can almost always reach 30, but going beyond it feels like a sudden drop in willpower. Is that truly muscular failure? Not really. If I stop for even 20 seconds, I can often continue. What is happening here? My guess is that it’s a tug-of-war between prefrontal control, threat detection, central fatigue, and body feedback.

AI helped me

I shared the details above with AI and iterated through many rounds of discussion. It helped me understand the neuroscience behind this experience. The mechanism-level explanation is complex, so I kept it as a separate article: What’s happening in your body when training stalls.

More importantly, it gave me a “rational anchor”: this plateau shouldn’t be attacked with pure grit. It’s a systems problem, so I’m going to treat it as a small experiment.

My current understanding

For now, I’m treating my “limit” as risk management, not just muscle failure:

Performance ≈ capacity × movement economy × nervous-system permission

The most likely pattern for me:

  • the start signal gets “gated” before the first rep (that instant hesitation on the bar);
  • a weak link fails early (forearms/grip, elbow tolerance, scapular control), so pain arrives sooner;
  • once form degrades, perceived effort and injury risk jump, and “permission” clamps down earlier;
  • the 20-second push-up pause feels like it reduces acute cost (breathing strain, burning, perceived effort), and the system temporarily permits more output.

My 4-week experiment

Reset

I’m turning training from an “exam” into “practice.” In concrete terms:

  • No max tests for 4 weeks.
  • Leave RIR 2–3 on main work (stop when I could still do 2–3 clean reps).
  • Prioritize consistency and control.

A small warm-up (to fix the “no power at first touch” feeling)

  • Easy dead hang: 30–60 seconds (find scapular depression)
  • Scapular pull-ups: 2 sets × 6–10
  • Very easy pull-ups: 1–2 sets × 2–3 (just to make the first rep feel “available”)

3 sessions per week

  • Day A: quality volume
    Pull-ups: 5–8 sets × 2–4 reps (RIR 2–3, plenty of rest)
  • Day B: weak-link tolerance
    Slow eccentrics: 3–5 sets × 2–4 reps (3–6 seconds down)
    Assisted pull-ups: 2–4 sets × 6–10 reps (stable path)
  • Day C: density / endurance
    EMOM 10 minutes: 2–3 reps per minute (only if quality stays consistent)

Push-ups (same logic)

  • Don’t treat 30 as an “exam score.” Use multiple submax sets: for example 6–10 sets × 12–18 reps.
  • End each set with 1–2 reps in reserve so my body learns “controlled endings.”

Progress signals

  • The first rep feels smoother; less “fight” just to start.
  • More sets of 4 clean pull-ups with consistent technique.
  • Discomfort is more manageable (later onset, lower intensity, faster recovery).

Safety boundary

If I get sharp pain, pain that wakes me at night, pain that affects daily life, or pain that keeps worsening, I’ll reduce load and volume immediately and prioritize recovery.
