The Kelgramme difference
What helps you stay consistent.
The first reason people quit a program is lack of time, ahead of boredom and lack of follow-up. Kelgramme is built to remove those three obstacles.
- Sessions from 15 to 60 minutesYou pick the time you have; the program adapts the number of exercises and chains supersets when it has to be short.
- Loads recalculated after every setAfter a short night, performance drops by 8% on average: the app adjusts loads and reps to your form of the day and your real sets, instead of imposing a fixed plan.
- One challenge a week, a mascot that levels upEvery Monday, a challenge drawn from your own program. 13-week seasons, records, badges, and a mascot whose level follows your real training, never your screen time.
- Gym or home, with your equipmentOne kettlebell, two dumbbells or nothing at all: the program picks the variant you can do and tells you when to move up.
- Rules from studies, not trends121 PubMed studies built in and verifiable, one per programming rule.
- No account, no adsYour data stays on your phone; export and delete it anytime.
How it works
From your profile to your session, in three steps.
Set up your profile in 2 minutes
Enter your goal, your level, where you train (gym or home) and your equipment. Your tailored program is generated instantly.
Let the app guide your session
Follow your exercises, rest times and sets. Every movement is broken down muscle by muscle with its key points. Just log your reps and your RIR (reps in reserve).
Watch your loads adjust live
Every validated set recalculates the next one. Before you start, enter your sleep, energy and soreness: the algorithm refines today's session to help you progress while limiting injury risk. It's a proposal, you decide.
What really changes
Built for people who want real results.
Dynamic adjustment
Your readiness of the day (sleep, energy, soreness) instantly modulates your loads.
Interactive anatomy
124 exercises with animated plates showing prime movers, secondary muscles and stabilisers.
Smart pain management
Discomfort on an exercise? Report it: the app lightens the load and tracks how it evolves session after session.
Total flexibility
A missed session doesn't break your cycle. Switch on “short on time” mode to trim a session while keeping the essentials. Offline mode included.
Precise, scientific tracking
Records, weekly tonnage, estimated maxes, load ratio and 13 progress badges. Excel export and Garmin compatibility.
Programs for every goal
A tailor-made programme for every goal, held to the same scientific standard.
13-week cycles built in 4-week blocks, with a built-in deload week.
Strength training (men & women)
Muscle gain, strength or weight loss. 2 to 5 sessions a week, at the gym or at home.
Same scientific rigour for everyone: studies give no reason for a “lighter” program for women.
Combat sports
MMA, boxing, judo, grappling, kickboxing. Strength and conditioning built to boost your strength and explosiveness without compromising your fight training.
General fitness
Moderate-intensity programs, inspired by the WHO physical activity guidelines for adults: daily walking and gentle return cycles after a break.
The science behind Kelgramme
Every rule comes from a study. Every study can be checked.
No “broscience” and no passing fads. Kelgramme draws on 121 scientific studies, published between 1976 and 2025, indexed by their DOI and verified one by one on PubMed.

Who is behind Kelgramme?
Rigorous design by a hands-on professional.
I'm Kelly Voitus, founder of Kelgramme. I designed the app with two points of view: that of an exercise professional, and that of a deputy director of healthcare facilities, used to quality standards.
- Education Bachelor's degree in adapted physical activity (APA), then a Master's degree in Sport Science (STAPS, Sport and Health Engineering) at the University of La Réunion. Specialised Master's in healthcare and social care management (TBS).
- In the field Rehabilitation in the healthcare sector as an APA teacher, and one-to-one coaching.
- Management Deputy director of a nursing home, then of rehabilitation clinics, in charge of quality and of preparing for the French health authority (HAS) certifications.
- Digital health Project manager for the rollout of an electronic patient record across seven facilities: staff training and step-by-step procedures.
- Practice More than ten years of disciplined strength training.
Kelgramme follows the same method: rules drawn from studies, written plainly, and open to checking on the Sources page.
