I've been personally using Relay since April and it's blown TeamBuildr out of the water.

PaoloPaolo@pgp_strengthandconditioning
The AI is beyond imagination. It makes programming so much faster, and it's something no one's ever offered. Once you see the workflow, it just makes total sense.
MaddyMaddy@maddyzarchin
I am always looking for ways to optimize my athletes' experience and improve my ability to help them progress in a virtual setting. Relay has provided me with an ideal solution for effective programming and easy setup for my athletes. Relay allows me to easily track, plan, and adjust various programming throughout their seasons.
ChavdarChavdar@chavdar.nedev
Relay helps me to structure my programs in a very efficient way. I can plan and customize for my entire roster in a few clicks, saving me lots of time. Finally I can focus on what really matters!
CarlCarl@sledge.strength
Relay's back of house programming system allows me to implement my mantra of providing a world class service in every environment I am in. It cuts out the repetitive work that takes 90% of time so I can focus on the 10% of details that matter to get the extra 1% out of my athletes.
ErykEryk@eryk.bandera.trener
I love that Relay has everything I care about while programming: simplicity, monitoring, a convenient interface for me and the player, and an aesthetic design.
AnthonyAnthony@antonylappas
Relay Athletic is helping me a lot to improve and elevate my job and I am really thankful for letting me be part of their community.
LiamLiam@evans.performance
As a coach who's tried almost all platforms out there, Relay felt like I finally found the right one. Others had some good features and different reasons why I liked them but with relay I finally feel like I have everything I need to not only give the athletes the best training experience but also myself the best coaching experience. I'm responsible for well over 100 athletes so having a software that lets me be more efficient programming for them as well as monitoring all of them is a game changer. After speaking closely with the team I also know how much they care about listening to the needs of coaches and I know the platform will continue to grow and get even better than it already is.

You can basically program on Relay without leaving your keyboard. I tried it out and the efficiency is just off the charts, and the AI thing is moving into the right space.
Daniel DayDaniel Day@crftd.athlete
With Relay I can run my coaching from anywhere in the world, and my athletes still get the best experience.
HudsonHudson@hparishh
Relay has changed how I program, and has saved me hours per week working with my athletes, and my online business. Easy to use and incredibly efficient.
JakubJakub@kuba_szyszka_scc
In my work, I place particular emphasis on critical thinking about training, its impact on health, and improving effectiveness. I believe in the power of collaboration and commitment, which lead to meaningful achievements. This is why I chose Relay.
Luca DoliwaLuca Doliwa@sld49
The time I'm saving with Relay Athletics gives me the opportunity to focus more on each athlete. Relay Athletics makes 1on1 and team coaching effortless with athletes around the globe.
LoganLogan@rempelperformanceandhealth
Relay Athletic is a breath of fresh air in a stagnant S&C coaching software market. I'm excited to grow with them, and the Relay team has been awesome to work with. At T3 Fitness and Kinesiology, I work with clients ranging from older adults managing chronic conditions to athletes chasing performance. My philosophy is simple: meet people where they are, assess inefficiencies, and improve them. The goal is to help people out of pain, enhance their quality of life, and perform at their highest level. Relay saves me time, my most valuable asset as a busy business owner of 2 exercise clinics. All while keeping clients clear, engaged, and accountable every session.

Frequently asked questions

The questions coaches actually ask us, answered.

Who is Relay built for?

Strength and conditioning coaches: professional squads, college programmes, private studios, rehab clinics and online rosters. Relay is built around resistance training, and coaches also use it to programme conditioning, running, mixed modal sessions and return to play. If you are working out of spreadsheets, or out of a platform that only stores what you have already written, this is the swap. See how program design works.

How does Relay compare to TrainHeroic, TeamBuildr or TrueCoach?

Most platforms are somewhere to store programs you have already written. Relay is built around the writing itself: speak or type a session and it comes back structured, periodize a whole block in one pass, and apply one session across a roster on each athlete's own numbers. Delivery, logging, questionnaires and analytics work the way you expect them to.

Will the AI be programming for my athletes?

Only as far as you let it. You give it your rules once, in your own words, and it drafts inside them using your own exercise library. Nothing reaches an athlete until you assign it, and every set, rep and load stays editable. Plenty of coaches use Relay purely as a fast builder and never open the agent.

What is the coaching brain?

It is where you write down how you coach, once, in your own words: your principles, your progressions, the exercises you avoid and the ones you always reach for. Every draft the agent writes starts inside those rules and pulls from your own exercise library, and you can keep editing them as your thinking changes. The documentation walks through setting one up.

How is this different from asking ChatGPT or Claude?

A chat window gives you text you then have to retype somewhere. Relay's agent works inside your account: your library, your athletes, your programs, and the result is on their phones. If you already work in Claude or ChatGPT, you can connect them to Relay and drive it from there instead.

Which integrations does Relay support?

VALD, Kinvent and Hawkin Dynamics connect today. Link an athlete once and their test results land on their profile next to their training, ready to program against. More providers are in progress: book a call and tell us which one you need.

Is there a free trial?

Seven days, full access, and no credit card to start. After that Relay Plus starts at $10 a month, and paying yearly gives you two months free.

Can I bring my exercises, videos and programs with me?

Yes, and it is the first thing we help with. Export your exercise library from your current platform as CSV or Excel and Relay maps the columns for you, with your YouTube and Vimeo links still attached. Programs come across as files: attach a spreadsheet, a PDF, even a photo of the whiteboard, and the AI rebuilds it in Relay with the weeks and sessions intact.

Who owns the athlete data, and do you train AI models on it?

You own it, and no. Our terms state that you retain full ownership of everything you create in Relay, including programs, templates and athlete data. AI features are processed through the Google Gemini API, which does not use the content you send it to train its models, and Relay does not train models on your data either. Relay is GDPR compliant, athlete data is stored on European infrastructure, and it is encrypted in transit and at rest. Our privacy policy names every processor.

Who is behind Relay?

Relay runs day to day at clubs and universities including SV Darmstadt 98, Imoco Volley, ratiopharm ulm and Quinnipiac University.
