Log your training sets and pick a goal: a heavier lift, a first muscle-up, a leaner body. Auguste reads every session and coaches you there.
He reads your history and acts on it, mid session.
Finish the set, Straddly does the maths and tells your friends.
Over 1,000 exercises are animated, with the steps, the cues and the muscles they work.

A heat map that fills up as you train, plus the stats you pick to show.
“I used to scroll and compare myself to everyone. now I only compare with my own last session, and Auguste keeps pointing me toward where I actually want to be.”
“I have never logged a PR by hand and it still caught 92.5 for 4 on bench. the estimated 1RM is the bit that got me, I had no idea I was sat near 105.”
“the summary after a session gives me one thing to fix instead of a wall of stats. last week it said rest longer on the top set. did that, added 5kg.”

During a workout you can ask Auguste to swap an exercise, add a set or rebuild the session around the time you have left, and he edits the workout directly. After the session he reads your numbers and gives you one specific action for next time. He remembers your injuries, equipment and goals between sessions.
Yes. Share a workout reel from Instagram or TikTok to Straddly and it becomes a routine you can start right away, with the exercises, sets and reps filled in.
Every set you log is compared with your history. When you beat your best weight, reps, estimated 1RM, hold time or distance, Straddly marks it as a personal record and celebrates it, with no manual entry.
Straddly is available on Google Play for Android today. The iOS version is on its way.
The app is available in English, French, Spanish, Italian, German and Brazilian Portuguese and follows your phone language. The training blog is published in English, French, Spanish, German, Portuguese and Italian.
