Multi-cycle periodization
Macrocycle, mesocycle, microcycle. Program your full season with the right phases.
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.
You might just not regret it.
Built for your discipline.
A Google Sheet alternative, Unbrokn is built for athletic trainers, solo or in team, whether your athletes play rugby, basketball, football, combat sports, run or swim. Build your macrocycles (full season), mesocycles (4-6 weeks), microcycles with adapted periodization : max strength, power, strength endurance, aerobic, deload. Integrate your field tests (VO2max, vertical jumps, sprints, 1RM) and calibrate individual loads from the results. Each athlete sees their program in the app, you keep control of the whole team from your space.
The tools
that change everything for you.
Field tests
VMA, VO2max, vertical jumps, sprints, 1RM. Log results, calibrate individual loads.
Paces in %VMA, loads in %1RM
Write "85% VMA" or "75% 1RM Squat" in a block. 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 blocks
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, with roles for assistants.
Customizable weekly check-in
Session RPE, fatigue, sleep, pain, mood, or any question you want. Monitor internal load and adjust the next week.
Auto volume per pattern
Squat, Push, Pull, Hinge, Core-Carry. Weekly and monthly volume per pattern on the evolution page. Pilot load without compiling by hand.
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, alert above 1.5. Gabbett method, essential for managing injury risk in team settings.
Wellness score and insights
Score 0-100 on sleep, stress, recovery, soreness, fatigue. Over 12 weeks, the app produces plain-language summaries you can export ahead of a medical staff meeting.
Athletes to watch
Coach widget: inactive, repeated hard effort, reported injury, risky ACWR, dropping wellness. You know who to call before the next session.
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. You program your full season with the phases in the right place.
-
You log the results of your tests (VMA, VO2max, vertical jumps, sprints, 1RM) and calibrate individual loads from that data. By writing "85% VMA" or "75% 1RM Squat" in a block, each athlete sees their pace or load computed from their own results.
-
You get 14 days of free trial without a card. After that, three plans: Solo at 19 €/month (up to 20 athletes), Team at 49 €/month (up to 50 athletes, unlimited coaches), Pro at 79 €/month (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 blocks 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 with dedicated roles, and the athletes-to-watch widget tells you who to call before the next session.
-
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.

How to avoid overtraining: monotony, strain, ACWR
Overtraining doesn't come out of nowhere. It builds over 4 to 12 weeks, and three simple indicators let you see it coming: monotony, strain, acute-to-chronic ratio.
