Athletic training

The app for athletic trainers.

Macrocycles, mesocycles, microcycles. Field tests, calibrated loads per athlete, multi-sport piloting. For independents as well as teams.

30-day trial, no bank card.

Adapted to your discipline.

Rugby, basketball, football, combat sports, running or swimming: each athlete has their own needs, and Unbrokn lets you program each one, solo or as a team. Build your macrocycles (full season), mesocycles (4-6 weeks), microcycles with adapted periodization : max strength, power, strength endurance, aerobic, deload. MAS (maximal aerobic speed) and 1RM drive each athlete's paces and loads directly. Your other field tests (jumps, sprints) are logged as exercise scores and tracked over time. Each athlete sees their program in the app, you keep control of the whole team from your space.

The tools you will use every day.

Periodize your season

Lay out your macro, meso and micro cycles (max strength, power, endurance, deload) on the season view: the whole year on one screen, with your athletes' competitions.

Field tests

MAS and 1RM drive paces and loads directly. Your other tests (jumps, sprints) are logged as exercise scores and tracked over time.

Paces in %MAS, loads in %1RM

Write "85% MAS" (VMA in the app) or "75% 1RM Squat" in an exercise. Each athlete sees their pace (km/h + min/km) or load computed from their PRs. Your field tests drive the program directly.

Strength and metabolic exercises

Barbell sets, intervals, circuits. Every format for multi-quality prep.

Individual and team tracking

Each athlete has their program. You manage everything from one space, and your assistants have access to it.

Customizable weekly check-in

Session RPE, fatigue, sleep, pain, mood, or any question you want. Monitor internal load and adjust the next week.

Volume per pattern

Push, Pull, Legs. Tag your weight or reps exercises: weekly sessions per pattern and max lifted over 12 weeks, on the evolution page.

Progression curves

Tests and PRs tracked over time. Athletes see their evolution, you see the whole team's.

Flexible payment

One-shot prep or full season, monthly subscription or one-time, Klarna installments.

Team calendar or individual sessions

Calendar (Mon-Sun) for team tracking, numbered sessions (S1, S2, S3) for athletes juggling competitions, fields and travel. Independent choice athlete by athlete.

Internal load in AU (Foster sRPE)

Every session is rated RPE 1-10 and duration. Internal load aggregates each week over 12 weeks. Foster method, direct read of the load actually absorbed.

ACWR (Acute:Chronic Workload Ratio)

Ratio of acute load (7d) over chronic (28d). Optimal zone 0.8-1.3, risk zone above 1.5. Gabbett method, useful for managing injury risk in team settings.

Wellness score and insights

Tag the questions of your check-in (sleep, stress, recovery, soreness, fatigue): Unbrokn turns them into a score out of 100 and, over 12 weeks, plain-language summaries.

Total score and alert threshold

Add up the scales of your check-in (a Hooper index out of 28, for example) and set a threshold: you get alerted when an athlete crosses it.

Coach another discipline?

We adapted to each discipline with specialized coaches, without ever complicating the tool.

Frequently asked questions.

Yes. You build your macrocycles, mesocycles and microcycles with the right periodization: max strength, power, strength endurance, aerobic, deload. On the season view, you see the whole year and every phase in its place.

MAS and 1RM drive your programming directly: by writing "85% MAS" or "75% 1RM Squat" in an exercise, each athlete sees their pace or load computed from their own results. Your other tests (jumps, sprints) are logged as exercise scores and tracked over time.

You get 30 days of free trial without a card. After that, two plans: One at €15/month or €150/year (up to 10 athletes, a single coach) and Unlimited at €45/month or €450/year (unlimited athletes and coaches). The minimum price for a paid program is €5, with a trial period available up to 30 days for your athletes.

You rebuild your exercises once and save them as reusable templates. Once your library is in place, setting up a new cycle or adapting a prep from one athlete to another takes minutes.

Yes. Each athlete has their individual program, and you keep control of the whole team from the same space. You invite your assistants into the space, each of them gets access.

Yes, on iOS and Android. Each athlete sees their program, logs their sessions and RPE, and checks their progression curves. You track internal load in AU and the ACWR to manage injury risk in team settings.
