Thallo: Personal Trainer 40+

Thallo is your personal trainer for those over 40—for everyone who's getting back into it or has never trained systematically. It calculates instead of motivating.

WHY TRAINING IS DIFFERENT AT 40

Muscles still grow at 45 just as they did at 25—but everything around them has changed. Recovery takes longer, and those who ignore it will stagnate. Tendons and joints are no longer forgiving of sudden movements: shoulders, knees, and lower back are the first to complain. And your schedule is busier—two to three hours per week is realistic, not six. Typical training plans are designed for 25-year-olds and ignore all of this. Thallo is built from the ground up around these three points.

WHAT MAKES THALLO DIFFERENT

Other apps ask for your training plan first. Thallo first asks what you want to change—and then calculates your necessary weekly workload: how many hard sets per muscle group, distributed across the days you actually have. No pre-defined workout plan, but one tailored to your specific needs, including age, time commitment, experience, sleep patterns, and daily routine.

Simply tap on areas that feel uncomfortable. Exercises that strain those areas are permanently removed from your plan and replaced with suitable alternatives. Thallo doesn't offer medical advice—it simply filters your workouts.

HONEST INSTEAD OF LOUD

Thallo tells you what's realistic before your first workout: weights will feel lighter in two to three weeks, visible changes take eight to twelve weeks, and a significantly different upper body takes six to twelve months. Anyone who promises you more is just trying to sell you something.

If you're exhausted one day, tell the app—and it will reduce your set by a third. Doing less when your body is lagging behind is more effective than pushing through. Thallo calculates this for you.


Thallo DURING YOUR TRAINING

The training screen guides you instead of logging your progress: a large set counter, a tempo ring that visibly and audibly tracks the slow lowering phase, and a rest timer that explains why the rest period is so long. After each set, you enter the weight, repetitions, and perceived reserve—Thallo uses this information to calculate when to increase the weight.

PROGRESS YOU CAN SEE

A photo is taken every four weeks, always with the same orientation: the last image appears as a ghost image over the viewfinder, along with a grid and level. This way, you compare muscles, not shadows. The timeline shows you months in fast forward.

YOUR DATA STAYS YOURS

Thallo has no backend. Your profile, history, and photos are stored only on your device. Photos never end up in your gallery or on any server. No ads, no analytics services, no accounts.

PRICE

Onboarding, evaluation, the complete plan, and the first full training session are free. After that, Thallo costs €9.99 per month or €59.99 per year with a 7-day trial period.

Train for the life ahead.
