The fitness app for everyone.
Rubber Bands is a workout app built specifically for resistance band training. It generates personalized workouts around the exact bands and equipment you own, logs every set, and progresses your resistance automatically: an adaptive engine dampens outlier reps, scores consistency across sessions, and steps you up to the next band only when the data says you're ready. It ships with an Apple Watch app for on-wrist logging and live heart rate, and works fully offline with no account required.
Resistance band training is growing fast, driven by equipment innovations like loop bands, tube bands, and bars from X3®, Harambe®, Clench® and others. Bands offer an effective, convenient, and economical workout modality with an outstanding safety profile, and Rubber Bands is the only major training app built around them from the ground up.
Our mission is to make strength training work for every body and every budget by translating proven training principles to resistance bands, the most accessible strength equipment there is.
