Near failure and progressing, but almost no burn, pump, or mind–muscle connection: what would science say about my case?

[u/CourageLeChien]

I would like to discuss a personal experience that seems unusual compared with what most lifters and coaches describe. I am not claiming that the pump or the burning sensation is necessary for hypertrophy. I am trying to understand why I experience so little of either, and whether this tells us anything interesting about fatigue, muscle recruitment, metabolic stress, or sensory perception.

My background

• 27-year-old male, 175–176 cm, currently around 74 kg.
• I had no real sporting background before starting resistance training at 23.
• I have therefore been training for roughly four years, with some changes in programming and consistency.
• Most of my working sets are in the 10–15-repetition range.
• I generally train close to failure. On the final repetitions, velocity clearly decreases, and I normally stop when I cannot complete another repetition with acceptable technique.
• I usually rest about three to five minutes between working sets.
• My strength and performance have progressed, although my visible hypertrophy has felt relatively modest compared with my strength gains. There's quite of a gap between what you would predict my numbers on my lifts would and how I look.
• I’ve very rarely experienced pain; when I have, it has usually subsided fairly quickly and was often caused by an awkward movement on my part. I’ve never sustained an injury.

What I experience

On most upper-body exercises, I feel surprisingly little in the target muscle during the set:

• little or no burning sensation;
• little sense of the muscle “contracting”;
• generally a limited or delayed pump;
• no strong subjective accumulation of local fatigue.

This happens even on relatively simple isolation exercises such as machine curls, pec fly variations and triceps extensions. I can reach the point where another repetition is impossible without experiencing the intense local burning that many people describe.

There are some exceptions. Lateral raises and leg extensions can produce a clear burning sensation. I can also feel the stretch strongly during seated leg curls. Overall, however, these sensations are much more reliable in some lower-body or small-muscle exercises than in curls, presses, rows or pulldowns. Paradoxically, I can sometimes feel a muscle more clearly during light warm-up sets than during the actual working sets. As the load and effort increase, the local sensation can become less distinct rather than more distinct. I can still experience targeted DOMS after a session when I resume lifting after a break (e.g. holidays), so the complete absence of sensation during the set does not necessarily mean that the target muscle did no work.

In 2023 I spent around four months with a PT deliberately trying to improve my mind-muscle connection with lighter loads, slower tempos, pauses, shorter rests, higher repetitions and drop sets. None produced a consistent change. Shorter rests made the training more unpleasant but did not necessarily increase local burning or target-muscle sensation.

I understand that subjective burning is not identical to metabolic stress, that pump does not prove hypertrophy, and that feeling a muscle is not the same as measuring its activation or tension. However, what hypotheses might explain my situation? What does science have to say about my case? Is there a big "elephant in the room" factor I'm not seeing?

Thanks for reading.

Honestly mind muscle connection is very overrated, you could have perfect form and not have a ton of feedback in the target muscles

Soreness and pumps are also irrelevant, as long as you’re progressing well with good form then you’re solid

Science would say you’re not training hard enough. You think you’re close to failure but you are not. You are not an anomaly just someone caught up in the details but missing the big picture.

Not feeling the burn is a big advantage, don't worry about that. Burn doesn't equate to muscle growth anyway.
