Indy is the coach inside IndexFit. Tell it what you're after and it writes your lifting, running and calorie plan, checks in after every session, and changes the plan when your week changes.
Free to start. No card needed.

“Lose 12 lb and run my first 10K.”
How many days a week, and for how long?

Every card can be edited. Nothing starts until you approve it.
Everything you do lands in the same place, so Indy sees the whole week: the heavy squat day, the long run after it, and the pizza in between.
Lifting
Log a set in two taps. Hit every rep and the weight goes up next time. Miss, and it holds. New PRs get spotted for you.
Bench Press
3 × 8 · 2 of 3 done
Hit 8 reps on every set to add weight.
Running
Start a run on your iPhone or Apple Watch. Indy sets the pace for easy days and long days, and moves runs when your week shifts.
Easy run Tuesday
Food
Snap your plate and Indy cuts each food out as a sticker with its calories and protein. In a rush? Just type what you ate.

Finish a workout or a run and Indy compares it with the plan, asks how it felt, and sets up the next one.
Mornings and evenings it looks over your week and moves things when it needs to. Every change comes with an Undo.
Workout check-in
You hit every rep on squats.

Start a league, send the invite link, and go head to head each week. Lifting volume, miles, training days and PRs all score, with caps so nobody wins on one thing alone. Up to 38 people a league, group chat included.
