The proof
We don't guess.
We check.
We give LˊOdin the same training the lifters in a published study did — same lifts, same sets, same weeks — and line its numbers up against what those lifters really gained. Land inside the study's margin and it's a hit. Close doesn't count.

Real lifters = the study group's average. LˊOdin's numbers are from its full study run in late September 2026; hit counts from the October 1, 2026 recount. Studies: Schoenfeld et al. 2019 · Mitchell et al. 2012 · Hamarsland et al. 2022.
What it plans
One app. Every kind of training.
Strength, muscle, endurance and skills — plus the stuff other apps skip, like time off and your very first pull-up.
Plans the whole block
Not just today. Build-up weeks, a lighter week to recover and a test day to show what you've got.
Your first pull-up
Can't do one yet? LˊOdin plans assisted pull-ups and cuts the help as you get stronger — until it's all you.
Learn a skill
Chasing the Olympic lifts or a new move? Practice gets planned into your weeks until it's yours.
Build endurance
More reps at the same weight, week after week. Endurance goals get planned like everything else.
Lifting and cardio, one plan
Mix conditioning into your lifting week. LˊOdin counts both, so your growth tracking knows about the cardio too.
See your muscles grow
Growth tracked muscle by muscle from every set you log. Add tape measurements and watch them move.
Time off? It adjusts.
Sick, busy or on vacation? LˊOdin knows strength fades a little during a break and plans your way back.
Watch your strength climb
Your maxes update as you lift. See them rise week after week.
Back Squat max, week by week
Weights that fit your gym
No more 237.5 lb when your smallest plates are 5s. Every weight is rounded to the plates and machines you actually have.
Short on time? It fits the day
Tell it you've got 45 minutes. It trims the day to fit and keeps the lifts that matter most.
Every set counts
Warm-ups, top sets, back-off sets — all of your work counts toward your growth, and next week's plan knows it.
Why LˊOdin
Not another slop app.
Plenty of fitness apps make things up. Here's the difference.

FAQ
Questions, answered.
What is LˊOdin?
A training app that plans every workout for you — the exercises, sets, reps and weights, weeks and months ahead — and builds each new week from what you actually lifted. The math behind it is tested against 100+ published training studies.
Is this an AI app?
No chatbot writes your plan. LˊOdin's plans come from training math, and that math is tested against what real lifters gained in published studies.
What's a hit?
We give LˊOdin the same training the lifters in a published study did, then compare its number with what those lifters actually gained. Every result has a target: the range the study reported, or a tight margin around its average when it reports none (on a lift, 2 lb or 5%, whichever is bigger). Inside the target is a hit. Anything else is a miss — close doesn't count. At our last full recount, on October 1, 2026, that came to 392 hits out of 935 graded results. We keep working on the rest.
Do I need to understand any of this?
No. You lift. LˊOdin does the math.
Who is it for?
Anyone who lifts with a goal: getting stronger, building muscle, more power or endurance, learning a skill like the Olympic lifts — or getting your very first pull-up. If you can follow a plan and log your sets, LˊOdin does the rest.
Do I need a full gym?
No. Tell LˊOdin what you have — barbells, dumbbells, kettlebells, cables or machines — and it plans with that gear and rounds every weight to what you can actually load.
Can I change the plan?
Yes. Swap an exercise, change the sets or the weight, or skip a lift. LˊOdin keeps your changes and builds around them.
Where is my data kept?
On LˊOdin's own server. Your workouts and history are kept there so your plan is ready wherever you open the app.
What does it cost?
Pricing hasn't been set yet. Early access members hear it first.
