Why we built it

We liked the training. We didn't like the app.

bellos started with a popular workout app that one of us used. The training was good: heavy days, light days, more variety when the weight came down. The app wasn't. It kept losing sets, its plans ignored what had actually been lifted, and there was no way to look back at past workouts.

So we worked out what the method actually was, wrote the rules down, checked them against the research, and built the app we wanted. It's quiet, it remembers everything, and it gets better every time someone tells us what's missing.

Questions

Before you sign up

What does the beta cost?

Nothing. The beta is free. If that ever changes, we'll tell you first, and leaving is one tap.

How do I get in?

Join the waitlist and we'll invite people in small groups, starting with those whose training fits the current plan. We send one email when your spot is ready.

What do I need?

A phone, and a gym with the usual machines, cables and dumbbells. bellos installs from your browser, works offline at the gym, and keeps your phone and computer in sync.

Is this a meal plan or a coaching app?

No. bellos plans and logs your lifting. It doesn't do meals, chat or social features, and it won't nag you.

What happens to my email and my workouts?

Your email is used to invite you and nothing else. Your workout logs are yours: we never sell them, analytics stay minimal, and you can export everything at any time. Our privacy policy has the details.
