What's New in REBL

1.10.1

July 26, 2026

trAIner is now REBL — new name, same coach. Also in this update: • Readiness scoring tuned — the load model now tracks fitness vs. fatigue as they build over time, so the score better reflects how training accumulates • Clearer framing when a deload week reads Light (that means it's working) • Bug fixes across the workout flow

Loved the customization

This is a really great app- I’m new to working out and it helped meet me where I’m at

Keeps me accountable

This app has made it way easier to stay on top of my training. Logging workouts is quick, everything stays organized, and seeing my progress keeps me motivated to keep showing up. Definitely recommend it to anyone looking to stay consistent and make progress!

Took the guesswork out for me

Finally a workout tracker that does the thinking for me — it gives me the
exact next weight and reps. The AI coaching is genuinely helpful and adapts as you go. Simple, clean, it's kept me consistent and pushed me more than I would have done myself.

The best!!!

I’ve used a lot of workout apps. This one is heads and shoulder above the rest. It actually gives me a routine I can follow, the AI tells me what I should be doing and gives me feedback about my actual workload (aka how much I’m lifting). It’s been a game changer!! I’m on a 3 week streak!
