A program on Fiz is a real block: weeks and days, in order. Start at week 1, log each session as you go, and pick up exactly where you left off. Follow one someone else published, or build your own.
- Weeks and days, in order. Everyone starts at week 1 and works forward. No guessing what today is.
- Build it by hand, free. Three of your own programs on the free tier, session by session, your structure.
- Or describe the goal. Pro generates a full multi-week program from a sentence, then writes next week when you're ready for it.
- Smart Adjust. Pro reads what you actually logged and rewrites the sessions ahead: heavier, lighter, or left alone.
- Yours or everyone's. Keep a program private, or publish it and let anyone follow along.

Pick a workout, pick someone you follow, add a taunt if you're feeling it. They answer with a fresh attempt or a score they've already got in the bank, and Fiz settles it on the section score. Free, for everyone.
- Call out anyone you follow. One workout, one score, one winner. No bracket, no admin.
- Or throw it open. Drop a link in the group chat and the first person to claim it takes the fight.
- Squads, too. Free private groups. Add your mutuals and run a throwdown across the whole squad.
- Declining is silent. Nobody gets a notification that you passed. No hard feelings.
- In Play. One screen for everything you've got riding, and it tells you plainly when nothing needs you.

What is Fiz?
Fiz is a social fitness app for functional and hybrid training, available on iOS and Android. A social home for your workouts, whatever your level. Create workouts with AI or a full manual
editor, share them publicly, remix other people's workouts, log scores, and join leaderboards when you
feel like it. Covers functional fitness, hybrid racing, triathlon, and everyday strength and conditioning, whether you train at a gym, at home, or outside.
How does AI workout creation work?
Describe what you want, say "a 20-minute AMRAP with kettlebells and pull-ups", and Fiz
generates a fully structured workout with proper movement selection, rep schemes, and time caps. Fine-tune
in the manual editor before publishing.
Can I remix other people's workouts?
Yes. Every published workout on Fiz can be remixed. Take any workout you find, swap
movements to match your equipment and level, adjust the rep scheme, publish your version. The original
creator gets credit and the remix links back to the source.
Do I need to be fit already to use Fiz?
No. Fiz is built for every level. Every workout can be scaled: swap movements, lower the loads, shorten the time. It still counts. The Foundations programme is a guided on-ramp for your
first weeks, and you choose whether you appear on leaderboards at all.
What is a Throwdown?
A head-to-head call-out on a single workout. Pick a workout, pick someone you follow,
add a taunt if you fancy it, and send it. They answer with a fresh attempt or a score they've already
logged, and Fiz settles it on the section score. You can also share an open Throwdown link into any group chat, and the first person to claim it takes the fight. Declining is silent, so nobody gets a notification
about it. Throwdowns are free.
Can I follow a multi-week program?
Yes. Programs on Fiz are structured multi-week blocks: weeks and days, not a loose pile
of workouts. Follow one and you start at week 1 and work forward, logging each session as you go. You can
build a program by hand for free, and Fiz Pro can generate a full multi-week program from a goal, then use
Smart Adjust to rewrite the sessions ahead based on what you actually logged.
What are challenges and badges?
Challenges are time-boxed goals with their own leaderboard: global ones Fiz runs,
community ones, and private invite-only ones. Some rank individual scores; others pool everyone's work
toward a shared target. There's also a fresh Workout of the Week for everyone, with its own badge. Finish a
challenge and you earn a badge, which lands on the activity that completed it and gets its own share card.
Joining and creating challenges is free.
What's the difference between a group and a community?
A group is a small private squad. You add people you follow who follow you back, and it
stays invisible to everyone else. Groups are free. A community is a bigger, named place with its own feed,
announcements, a pinned workout of the week, and member-scoped leaderboards; it can be public or private.
Joining a community is free for everyone, and creating one needs Fiz Pro.
Is Fiz free?
Fiz is free to download and use. Create workouts, share them, submit scores, follow
friends, throw down against your mates, start a private group, join challenges, free, forever. Fiz Pro
adds creator tools like affiliate codes, collections, communities, and Smart Workouts & Programs, and starts with a 1-week free trial.
What devices does Fiz work on?
Fiz is on iOS and Android. The app integrates with Apple Health, Health Connect, and
major wearables for heart rate, calorie tracking, and workout metrics.
Can I create a community for my gym?
Yes. Communities are a Pro feature: spin one up as public or private, post workouts and
announcements, pin the workout of the week, scope leaderboards to members. Joining a community is free for everyone. Only creating one needs Pro.
