Why did my workout app keep my weight too light?

A beta tester described this in her own words: "I did one set at 10 lbs, and then it took me back to 5 lbs, so my second and third set was at 5 pounds, which was easy, and it didn't up the lbs." One hard set, and the app never let her back up for the rest of the exercise. She finished the whole movement at a weight that felt like a warm-up. That was a real bug, not a misunderstanding.

What was happening

Auto-regulated training is supposed to work both ways: back off after a hard set, climb back up after an easy one. The backing-off half worked as designed. The climbing-back-up half had a gap. On a conservative target, the easiest answer you could give about how a set felt still read as "on target," which meant hold, not go back up. A weight that dropped once, correctly, for one hard set could get stuck at the bottom for the rest of the exercise, no matter how easy the following sets felt.

The tester gave the same "too easy" feedback on set two and set three, and the app read both the same way: confirmation to hold, not a signal to climb.

The fix

The app now compares an easy set against the heaviest weight you've already handled that session, not just against a fixed target. If you're lifting light and you've already proven you can handle more today, the next set climbs back toward that number instead of sitting frozen. It's capped at what you've already shown you can do, so it won't overshoot a weight you haven't actually proven yet.

A session that dips after one unexpectedly hard set can now recover within the same exercise, instead of writing off the rest of it. The weight climbs back toward your proven number on the next set that reads as easy.

Part of why Yield's numbers are actually trustworthy.
