Workout context ready

I missed two workouts. How should I adjust this week?

Keep today's session. Move your second lower-body day to Saturday and reduce each main lift by one set.

Resume your normal split Monday—no catch-up workouts needed.

Personalized from Marlin's workout history
GymBuddy recommends rescheduling one lower-body session and reducing working sets after two missed workouts.

Why Revenge Arc exists

You don’t need
a perfect week.
You need a next step.

Training in one place. Meals in another. Progress somewhere else. It’s a lot to hold together when you’re just trying to show up.

Revenge Arc brings those pieces into one connected system, built around a simple idea: make the next useful action easier to see.

A missed day doesn’t erase your work. There’s always another set, another meal, another chance to build momentum.

What is Revenge Arc?

Revenge Arc is an all-in-one fitness system for training, nutrition, AI guidance, progress, and community. The goal is simple: make the next useful action easier to see and keep your momentum connected.

Is there a free plan?

No. Revenge Arc is offered through weekly, monthly, and yearly subscriptions. Your plan is selected and managed inside the iOS app through Apple’s subscription system.

Where do I choose a subscription plan?

Choose and manage your plan inside the app after downloading it from the App Store. Website pricing buttons lead to the same App Store listing once the public listing is available.

Does GymBuddy replace a doctor, dietitian, or coach?

No. GymBuddy offers educational fitness guidance, not medical diagnosis or professional healthcare. Use qualified professionals for medical, injury, nutrition, or safety decisions that require personal clinical judgment.

How does the community shape the app?

Members can request improvements and share feedback. We prioritize the most useful ideas, build them carefully, release them, and keep improving based on real use.
