Strong Body. Strong Mind.

There are better places to go if you want to run, cycle, or chase your heart rate. But us? We love shifting heavy things.

Because nothing transforms you like strength does - it builds the body and the mind.

Every body is different.

But most programs act like they're not. One-size-fits-all. Rigid. Static.

You need a program that's informed by science - and built around you.

That's why we built Resistance. A personalized workout app with adaptive strength training that evolves as you do.

[HOW WE ADAPT]

A Fitness Approach Built Just For You

Busy Gym? No problem.

Bench taken? Dumbbells missing? Someone doing curls in the squat rack..? Your session adapts on the fly-swapping movements that keep the same stimulus, muscles, and intent. You stay in flow, hit the target, and leave with the work done.

Progress VS Program.

Life happens. Miss a session-or always skip leg day? We re-plan the week to keep you progressing toward your goal. Each week we score progress vs. target and update volume, intensity, and focus-so you keep moving forward without plateaus.

Anthropometric Analysis

Every body moves differently. Take squats: your femur-tibia ratio shapes stance and depth, while torso length influences back angle and bar position. We surface these levers-so from day one you know the form that fits your structure and the cues that unlock safer, stronger lifts.
