A minimalist kettlebell trainer.
Bellwork prescribes just two movements — the kettlebell swing and the Turkish get-up — and handles the rest: how many reps, which kettlebell, when to make things harder, and when to back off. You open the app, do the short workout it gives you, and log it. You never have to design a program.
Coming soon to the App Store for iPhone.
The program
The two movements and the way they're dosed come from Pavel Tsatsouline's kettlebell prescription, the program he calls Simple & Sinister. (No affiliation — we are simply fans of his work.) The premise is that a large amount of strength, conditioning, and resilience can be built from two exercises done consistently: the kettlebell swing for the hips and posterior chain, and the Turkish get-up for shoulder stability, mobility, and full-body control.
Bellwork starts you well below the program's target — with the lightest kettlebell you have access to and low reps — and walks you up gradually. The point is never to grind to failure: workouts stay short, repeatable, and technically clean.
How progression works
When you complete workouts, Bellwork makes exactly one thing harder at a time — usually more swing or get-up volume first, then a heavier kettlebell, a harder swing style, or shorter rest between swing sets. When a workout goes badly, it pauses progression and makes the next workout a little easier so you can get your footing.
You stay in control. You can let Bellwork calculate each workout automatically or progress manually, tell it which kettlebells you own, set your schedule, and override any decision it makes.
Private by design
Bellwork keeps all of your data on your device and sends none of it anywhere. There are no accounts, no servers, no analytics, and no tracking. Apple Health integration is optional and off until you enable it. Read the full privacy policy.
