Teenagersare notsmall adults.
AI-powered workouts, nutrition tracking and progress analytics designed for teens aged 13–18 — where the plan adapts to a body that’s still growing.
What is Athletics Crew?
A fitness app designed exclusively for teenagers. Unlike adult-focused platforms, Athletics Crew understands that teenage bodies are still growing. Workouts, nutrition guidance and training programs are calibrated for ages 13–18, so every exercise is safe, age-appropriate and effective.
Founded by Kai Forbes. Built by teens, for teens. The best way to build something teenagers actually use is to have teenagers build it. The team knows the real pressures — balancing school and sport, and navigating the noise around body image. Athletics Crew focuses on healthy habits, not unrealistic standards.
AI personalisation that adapts to you. Photo recognition analyses your meals, camera-based form feedback corrects your technique in real time, and your program is shaped by your goals, your available time and your current level.
Progress tracking that keeps you going. Detailed analytics, achievement badges, weekly progress photos, monthly transformation videos and a competitive league system that makes training something you look forward to.
Safe, supportive and pressure-free. Consistency over intensity. Progress over perfection. Self-improvement over comparison. Parents can trust that this is a platform built around their teenager’s wellbeing.
Most fitness apps assume
a finished body.
Stable hormones, predictable recovery, calories you can manipulate without consequence.
Growth plates still open, coordination still rewiring, habits that have to last decades.
Between 12 and 18 the body goes through one of its most significant periods of change. Bones are lengthening. Hormones are shifting. The nervous system is rewiring itself for coordination, strength and skill. That isn’t a limitation — it’s an opportunity. But it requires a different approach.
Training during adolescence shapes movement patterns, injury risk and physical confidence for life. How you move, how you recover, how you listen to your body — that becomes the foundation for everything after. The gym should be a learning environment, not a stress test.
Mistakes at this stage don’t just cause short-term setbacks. They shape long-term movement quality, injury risk, and a young person’s whole relationship with exercise.
This isn’t adult fitness with a younger skin. It’s a different operating system, built for adolescence — one that detects growth phases, caps load automatically, prioritises technique over intensity, fuels development and protects long-term health.
Built for growing bodies, not finished ones
Technique before load
Training prioritises movement quality, coordination, balance and control — not how much weight is lifted. The gym is treated as a motor-learning environment, not a stress test.
Progression without pressure
Progress is non-linear and submaximal. No constant max testing, no ego-driven targets, and no assumption that more is always better. Most sessions stay at a moderate level of effort, on purpose.
Injury prevention is the foundation
Open growth plates, vulnerable tendon-bone junctions and rapid fatigue under stress are treated as design constraints — not afterthoughts. Volume is capped. Asymmetries are addressed. Recovery is respected.
Adaptation to development, not age
Two teens of the same age can be in completely different stages of puberty. Training adapts to growth spurts and coordination changes instead of forcing a one-size-fits-all plan on a birth year.
Food is fuel here.
Never something to control.
Teenagers don’t eat to cut or bulk. They eat to grow.

Building confidence,
not comparison
Training during your teenage years shapes identity, not just your body. The goal isn’t to peak at 16 — it’s to build habits that last a lifetime.

Three taps, most days
Log what you ate, train the session, watch the line go up.
Photograph the plate. You get a breakdown and a plain-language note — never a limit to stay under.
The session is built for your stage of development, with rest days planned in rather than earned.
Charts track what you can do — load, reps, consistency — over months rather than days.

Success stories
Real teens, real results.
Maya, 15
Arizona, USA
Gymnastics
I could do the skills but I'd gas out halfway through my routine. The strength and mobility workouts fixed that — I finally have the core and control to hold my positions.
Sofia, 16
São Paulo, Brazil
Volleyball
My vertical was holding me back and I didn't know how to train for it. Athletics Crew gave me actual leg and explosive work instead of random gym stuff.
Marcus, 17
Texas, USA
Basketball
I had no clue where to start in a gym. Tracking my meals and following the workouts, I got way fitter. I made varsity this year — something I didn't think was possible last summer.
Jayden, 16
London, UK
Strength
Nothing I tried was working. The app showed me how to actually train and eat enough to grow. A year later I'm the strongest I've ever been.

Positive community
Competitive leagues provide healthy motivation without toxic culture. Your teen competes to improve themselves.
Peace of mind for you,
progress for them
My daughter used to spend hours on TikTok. Now she’s excited to show me her workout streaks and the new exercises she’s unlocked. The form detection even helped her fix a squat issue that was causing knee pain. As a parent, knowing she’s exercising safely with proper form — that’s priceless.
