Your IsoMax isn't coming back. Your training doesn't have to stop.
Dragon Door has closed its doors. The Force Board picks up where the IsoMax left off, with the same full-body isometric training and a lot more to show for it.
The tool you trusted is gone.
If you trained with the IsoMax, you already know what most lifters never figure out: measurable isometrics build serious strength with almost no joint wear and almost no time. You found the thing that worked.
Then Dragon Door shut down. No more units. No more straps or parts. No more support if something breaks. The device that anchored your training is now a device you can't replace.
You have two options. Hope your hardware lasts forever. Or find something built to take it further.
A number on a screen was never the whole point.
The IsoMax gave you a readout. You pulled, you saw a number, and then the number was gone. Tracking progress meant a notebook, a spreadsheet, or your memory.
Strength is built on what you can measure over time, not what you saw for two seconds last Tuesday. The next tool shouldn't just tell you how hard you pulled. It should remember every rep, show you the trend, and tell you when you're actually getting stronger.
That's the shift. From a readout you forget to a record you keep.
Meet the Force Board
The Force Board is a portable, app-connected force gauge for measurable isometric strength training. Same idea you already love. Built for the way you actually train.
Set it up anywhere and train your whole body isometrically: squat, deadlift, bench, overhead press, curl, row, shrug, calf raise, and more. Generate up to 660 lb (300 kg) of force against it. Then watch every rep land in the app.
- Every rep, tracked. Bluetooth syncs each pull to the app on iOS and Android. Peak force, history, and progress over time, automatically.
- Built-in testing. Peak force and critical force assessments tell you where you stand and when you've improved.
- Routines and templates. Follow proven isometric programs or build your own.
- Truly portable. The travel platform weighs 1.6 lb. Train at home, at the gym, or on the road.
- Backed by a company that's still here. Real support, real warranty, real updates. Not a discontinued product.

Questions from IsoMax owners
Will it feel familiar if I came from the IsoMax?
Yes. It's the same overcoming-isometric training: you pull or press against an immovable resistance and the device reads your force. The big difference is what happens after the rep. It gets saved.
Can I really train my whole body?
Yes. Squat, deadlift, bench, press, curl, row, shrug, calf raise, pull-up, and more, all isometric, all from one device.
Do I need the app?
The app is where the value lives: tracking, testing, routines, and progress. It works on iOS and Android, with a free tier and an optional Pro tier.
How much force can it handle?
Up to 1000 lb (450 kg). More than enough for max-effort isometric work.
What about support?
Force Board is an active product from PitchSix, with warranty and ongoing software updates.
