About this app

Your best training years aren't behind you.

Most fitness apps were built for 25-year-olds — all intensity, no regard for the knee you had replaced, the arthritis you manage, or the shoulder that never fully came back. MastersFit is different. It's personalized strength training for people over 40 who want to get genuinely strong while training around real injuries, joint issues, and past procedures.

PERSONALIZED IN MINUTES
Tell MastersFit about your goals, training history, injuries and limitations, available equipment, and schedule. In about five minutes it builds a training week shaped around you — not a one-size-fits-all template.

ADAPT IT WHEN YOU NEED TO
Replace an exercise that doesn't fit, exclude it from future workouts, or describe how today needs to change. MastersFit updates the workout while keeping you in control.

WHAT'S INSIDE
• A personalized training week, generated in minutes
• Exercises chosen around your injuries, limitations, and equipment
• Swap out any exercise that doesn't work for you — tell it why and it won't come back
• Adjust any workout in your own words and it re-plans
• Fast set logging — the plan learns from what you actually did
• Health Connect integration: heart rate in, completed workouts out
• Progress tracking built for the long game

MADE BY SOMEONE WHO'S TRAINED THROUGH THE SETBACKS
Created by a 64-year-old with two total knee replacements who deadlifts 405 pounds. Strength designed for a body with history — not in spite of one.

FOR EVERY KIND OF MASTERS ATHLETE
The comeback, the comeback-in-progress, and the never-stopped. Returning after a layoff, training around a flare-up, or just want a smarter plan — MastersFit meets your body where it is.

Your body has a history. Your training should respect it.

What’s new

Finishing a workout now ends with a celebration — a burst of confetti and a bit of haptic feedback when you close out your last set. It follows your Reduce Motion setting if you prefer a calmer experience.

Monthly subscribers can now switch to an annual plan without leaving the app, and see the savings before they do.

We also fixed the workout screen on narrower phones, where the Complete button could get squeezed, and made the action buttons easier to tap at larger text sizes.
