Strength & conditioning for your sport
You’re good at your sport. You’re not doing it full-time.
Maybe you’re a ski bum at heart with a desk you can’t quit. Maybe you’re forty-five with two kids and you’re still getting after it. Either way you get a handful of good days a year — don’t let the rest of your life rob you of them.
Treeline programs for the sport you actually do, around the week you actually have.
Who it's for
Nobody else is building for the middle
Training apps aim at the ends — someone who has never squatted, someone chasing a mirror, or someone whose whole day is training. In between there is everyone who is genuinely good at something and fits it around a life.
Not built for
- Beginners who need a squat taught
- Lifters training for the mirror
- Athletes with nothing else on
Built for
- People who have been doing this a while
- People who lift so they ski, run and ride better
- People with a job, a family, and a season they care about
Programming for your sport
Six questions, then a plan that serves your season
What you do, when your season is, how often you get out, what equipment you have. Then you tell it what your body will not do, in your own words, and it comes back with specific swaps and the reasoning behind each one.
What you type
“Right knee doesn’t like deep squats or high-rep lunges.”
What comes back
Same job for skiing, far less knee flexion under load.
Built for the week you actually have
Two sessions is a program, not a failure
An RPE on every set. Skipped sets recorded as skipped, not as missing. The days you bailed on, kept as what they were. Treeline records the training that happened rather than the training that was scheduled.
A phone on a bench, not a clipboard
Loggable with chalk on your hands
Every tappable row is at least 56 points. The next weight is already filled in from the last one you actually hit, and always overridable. A rest timer that survives you leaving the app.
Years, not weeks
What has Back Squat done since June?
Every set you have ever logged, per exercise, with a trend line over it. History follows the lift, so renaming an exercise or swapping a variant does not orphan the record.
