About this app

You didn't get lazy. You lost muscle.

Adults lose 3-8% of their muscle every decade after 30. Same food, same effort, smaller engine. That is why the program that worked at 25 stopped working, and why doing it harder did not fix it.

Start the free plan today. Three days a week, eight weeks, built around the body you have now.

😓 Tired of a program written for a 22-year-old with no job and no knees?
🦵 Training that used to work now aggravating a knee, a shoulder or a back?
🔁 Restarted for the fourth or fifth time and stopped trusting yourself?

YOUR PLAN IS FREE, AND IT STAYS FREE
Not free for a week. Free. The eight-week strength plan, workout logging, rest timers and your personal records do not expire and do not move behind a paywall later. No countdown on the part of the app that trains you.

BUILT FROM YOUR ANSWERS, NOT A TEMPLATE
Fifteen questions, about two minutes. Your goal, your training history, your equipment, the days you can actually train, and the joints that already complain. Every answer changes the plan.
- Three days a week by default, because four is where most people quit
- Every movement is one you can do with the equipment you told us about
- Eight weeks with a defined end, not an endless feed of workouts

AROUND THE JOINTS YOU ALREADY HAVE
Told us your knees or your shoulder are a problem? Those movements are not in the plan to begin with. Nothing to swap out mid-session, and no "modify as needed."

TRAINING THAT REMEMBERS
- Every exercise opens with a suggested weight based on your last session
- Built-in rest timers, so you are not guessing between sets
- Personal records tracked automatically as your lifts climb
- A running score built from sessions logged, records set and scans done

FOOD, WITHOUT A FOOD DIARY
There is no meal to log and nothing to weigh.
- A full meal plan with a grocery list that matches it
- Calories set from your height, weight, age, sex and activity using the Mifflin-St Jeor equation, with the arithmetic shown so you can check it rather than trust it
- Protein target based on your goal weight, not a flat guess
- Snap a photo of a meal and get calories and macros back

COACH D
An AI coach that has read your profile: your goal, your injuries, your equipment, your history. Ask it about a sore shoulder, a missed week, a plateau, or a hotel gym with no squat rack.

BODY SCAN
The scale cannot tell you whether the pound you lost was fat or muscle. The scan can: body fat percentage, lean mass, visceral fat, BMI and BMR, compared against your last one. It is an estimate from a formula, not a DEXA scan, and the app says so on the results screen.

WHAT IS PAID
$12.99 a month, or $79.99 a year: meal plans, the grocery list, the food photo scanner, unlimited coaching, monthly body scans and monthly progress reports.

New accounts also get the paid features free for the first week. When that week ends the paid features stop. Your workout plan does not. Cancel from inside the app, in two taps.

WHO THIS IS FOR
Adults 35 and over who used to be stronger than they are now. People restarting for the fourth or fifth time. Anyone whose last app was written for a 22-year-old with no job and no knees.

WHO IT IS NOT FOR
Beginners under 30, physique competitors, anyone who wants to drop a dress size before a wedding in six weeks, and anyone who wants to count calories. We took that out on purpose.

LetsBurnFit is a strength training and workout planner app for men and women over 40, covering gym workouts and home workouts, dumbbell and barbell training, a workout tracker with rest timer and personal records, an eight week weight lifting program, joint friendly exercise selection, and a meal plan with a grocery list. Works on any phone through the browser, with the Android app for training offline at the gym.

LetsBurnFit is a fitness app, not a medical device. Body composition figures are estimates from formulas, not diagnoses. Talk to a doctor before starting any exercise or nutrition program.

What’s new

Calories now count down. The Eat ring shows what you have left for the day, and the app tells you when you have reached your target.

Logging a meal no longer counts against you.

Bigger type throughout, and a tab bar you can actually see.

The meal scanner shows its progress while it reads your plate.

Fixes: training a day late now credits the day you trained. Losing signal no longer returns you to setup. Reduce Motion is respected everywhere.
