Shortcuts in the gym show up the first time you actually need the strength.

Partial reps and skipped sets still feel like training, which is what makes them easy to keep doing. The body builds what it was actually asked to do, and it is indifferent to how the session looked. Nothing tells you at the time. You find out later, at the moment you needed the thing to be there.

Pick quality over quantity for one session and see what it costs you in weight. Lighter and honest beats heavier and half. The number matters less than whether the movement was real.
