Attempt a record is deliberately kept separate from your regular training, both on screen and under the hood, because testing a single heavy lift is a different activity from a normal working set.
A made lift is logged as a genuine one-rep completed set — it counts toward your personal records and your recovery numbers exactly like any other lift you actually performed. A missed attempt is kept in your history for reference, but it's logged as an uncompleted set with zero reps, which every other engine in the app — personal records, progressive overload, and muscle recovery — quietly ignores. A miss can't drag down a target or read as unusual fatigue, because nothing in those engines ever sees it.
The whole session is also logged under the reserved name "Record Attempt," the same trick Quick Workout uses: no real routine can take that name, so a max-testing day can never advance a planned routine's targets. Testing your max and training toward it stay two different things.
When you're ready for your next attempt, BulkForged suggests a weight to try: a small jump over the last lift you made this session if you've already had one, otherwise your standing record, otherwise zero if you've never lifted this exercise before. It's a starting point — type over it any time.
