The problem
Spreadsheets do not coach anybody
A PDF tells your client what to do. It never tells you whether they did it. And an app built for sets and weight has nowhere to put “my client is on straddle, not full”.
Generic fitness apps track reps, not skill levels
Tiers are the plan: straddle, not full, and you both see it
You rewrite the same block for every client
Build once, assign to everyone, edit in one place
You have no idea who trained this week
Every set and hold they log lands in your dashboard
“Am I doing this right?” over text, again
A demo clip sits next to the movement itself
What you get
Everything a calisthenics coach needs. Nothing more.
Track the skills, not just the sets
Tuck, advanced tuck, straddle, full. Define the tiers once for front lever, planche or muscle-up, and watch every client move through them.
Build it once, assign it forever
Weeks, sessions, exercises, with sets, reps or hold times. Reorder anything, change a detail, and every client sees it instantly.
Show the movement
Attach a clip you filmed or a link you already host. Only your assigned clients can open it, through a link that expires.
See who actually trains
Clients tick each exercise and log what they really did: sets, reps, seconds held. You see progress per client, not guesses.
How it works
Three steps, then you are coaching
- 1
Build your program
Add weeks, then sessions, then exercises. Everything saves as you type, so there is no giant form to lose.
- 2
Send one link
Your client opens it, creates a free account, and the program is theirs. No app store, no payment, no friction.
- 3
Coach from what you see
Their logs land in your dashboard. You adjust the program; they get the change immediately.

Questions
Before you sign up
Do my clients have to pay?+
Never. Clients use Sthenix for free, forever. You pay the subscription; how you charge them is entirely your business and happens outside this product.
How do I get paid by my clients?+
However you already do: bank transfer, your own payment link, in person. We deliberately stay out of it, so there is no commission and no platform sitting between you and your athletes.
What happens if I cancel?+
Nothing is deleted. You keep reading everything you built, and your clients keep their programs and keep logging their training. You simply cannot create or edit until you resubscribe.
Can my clients see each other?+
No. A client sees only the programs assigned to them and their own logs. Coaches see only their own clients.
Is there a limit on clients or programs?+
No limit on either. Uploaded demo files are capped by storage, but external links cost nothing.
Do I need to install anything?+
No. It runs in the browser, on a phone as well as a laptop.
