Questions, answered.

Dumbly is a workout app for iPhone and iPad built around two dumbbells. It creates a workout plan based on your goal, fitness level and available time, then guides you through each session at home.

When you first open the app, you answer a few questions about your goal, your experience with strength training and how long you want each session to be. Dumbly uses your answers to build your plan. See how it works.

Dumbly is available for iPhone and iPad through the App Store. Check the App Store listing for the iOS and iPadOS versions it supports.

If you have an injury, a medical condition, are pregnant, or haven’t exercised in a long time, speak to a doctor or qualified professional before starting a new exercise program. Dumbly provides general fitness guidance, not medical advice.

A pair of dumbbells. Dumbly’s workouts are designed around two dumbbells, so you don’t need a gym or machines.

Choose a weight you can lift with control and good form through every rep. If you’re unsure, start lighter: you can make a set harder by adding reps or slowing down, and move to a heavier pair later. Adjustable dumbbells are a space-saving way to cover several weights.

Enough room to lie down and to extend your arms overhead and to the sides without hitting anything. Clear the area of trip hazards, and train on a stable, non-slip surface.

Yes. Select the beginner level during setup. Each exercise includes a demonstration so you can see the movement before you do it.

Dumbly offers beginner, intermediate and advanced levels. Your level sets the starting point for your plan, matching it to how much strength training you’ve done before.

You can train your full body in one session, or focus on your upper body, lower body or core.

You choose your preferred session length when you set up your plan. The app shows an estimated duration for each workout before you start.

Structured programs with a fixed length. Each one sets out workout days and rest days from start to finish, so you always know what today involves. Compare the challenges.

Choose the one you’re confident you can finish. If you’re new or returning to exercise, 30 days is a good place to start. The app shows the number of workouts and session length for each challenge before you begin.

No app can guarantee results. Progress depends on your starting point, consistency, sleep, nutrition and other factors. A challenge gives you a structured plan and a record of the work you’ve done.

Yes, you can follow your workouts offline.
