Assign
Pick an athlete or a whole team and set a start date. One program can serve a roster, each athlete on their own loads.
Program at the speed of thought
Everything it takes to write, periodize and adjust a training block. Built for coaches who program every day.
Trusted by 1000+ coaches and teams
Programming with a clear overview
Phases, progressions and sessions on one calendar, laid out the way you already plan them.
Split a program into phases the way you plan it on paper: Foundation, Deload, Power, Taper. Each phase gets a name, a colour and a week range, and the bar above the program shows the whole block at a glance.
“Relay allows me to easily track, plan, and adjust various programming throughout their seasons.”
The workout builder
Say the session out loud and it lands structured: exercises, sets, reps and notes, in the right block. Correct it in the same breath.
Templates
Reuse a whole program, a single session or a sequence of exercises, so nothing gets built twice.
You can basically program on Relay without leaving your keyboard. The speed is unimagined.
Export programs and workouts as PDF and Excel
A program that only lives in an app is a program you cannot hand to a head coach, a physio or a printer. Export any program or single workout in one click, with your own logo on it.
Send it to your athletes' phones in seconds.
Assign a program to an athlete or a whole team and it is in the Relay app on their phone, synced live.
On their phone
It appears in the Relay app on iPhone and Android, sessions in order, videos included.
Individual or for everyone
Adjust one athlete's copy on their own calendar, or change the main program and sync it to everyone assigned.
Sync to Athletes
Push template changes from Volleyball Off-Season Performance to assigned athletes. Completed or in-progress workouts are never overridden.

What the world's best coaches say
Relay is built with elite S&C professionals. Unfiltered feedback from coaches who work at the highest level of the sport.
Paolo@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.”
Maddy@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.”
Chavdar@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!”
Carl@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.”
Hudson@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.”
Eryk@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.”
Anthony@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.”
Liam@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.”
Joe Pedulla@pedullaperformance“Relay has singlehandedly optimized my programming and helped me add more revenue to my business. I am able to handle so many more clients with convenience, repeatable workflows and overall ease. The user interface is truly top of the line, and it's made programming so much more enjoyable. I genuinely don't see myself using another programming software, especially with how responsive and adaptable their team is.”
Brijesh Patel@bpatel515“I've been personally using Relay since April and it's blown TeamBuildr out of the water.”
Dario Saisan@saisantraining“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 Day@crftd.athlete“With Relay I can run my coaching from anywhere in the world, and my athletes still get the best experience.”
Case Grant@theathleticpt“Rather than spending hours typing out programming that I've already worked out in my head, Relay lets me quite literally speak it into existence and move onto the next athlete while I let Claude work it out.”
Jakub@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 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.”
Logan@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.”
Common questions
Does Relay support block periodization?
Yes. Lay out accumulation, intensification, realization and deload phases on the program, then use the periodization tab to progress volume and intensity across the weeks of each phase.
How do phases work?
A phase is a named, coloured range of weeks inside a program. You manage them from the bar above the weeks: add one, set its start and end week, pick a colour. Phases show in the periodization view and on the PDF export, and they adjust when you add or remove weeks.
Can I drag and drop sessions between days and weeks?
Yes. Drag a single session, a full training day, or a multi-day selection to anywhere in the program. The canvas updates the moment you drop, no saving and no refreshing.
Can I edit many sessions at once?
Yes. Drag-to-select across cells, then apply the same change to every selected session. Useful for shifting load across a phase, swapping an exercise everywhere it appears, or rolling a deload through a full block.
How does load selection work per athlete?
Prescribe sets in %1RM, RPE, RIR or tempo. When the program is assigned, Relay calculates each athlete's working weight from their own recorded maxes, in their own unit. Update a max and every future session recalculates.
Can I reuse programs and sessions?
Yes. Save any program as a template, any session as a workout template, and any sequence of exercises as a block template. Drop them into a new program and edit from there.
Can I export a program or a workout?
Yes. Export a whole program as a PDF calendar or as an Excel file with one sheet per workout, and any single workout as a PDF. Exports carry your organisation's name and logo, and the PDF shows your phases.
How does the program reach the athlete?
Assign the program and athletes see it in the Relay app on iPhone and Android. Every change you make to the canvas syncs to their phone instantly. No re-downloads, no PDFs, no re-sending.
What if my athletes cannot use phones in the facility?
Export the program as a PDF calendar, or as an Excel file with one sheet per workout, and print what the session needs. Single workouts export as a PDF too, and exports carry your organisation's name, logo and phases. An athlete who would rather not install anything can also train from a browser.
How does Voice AI fit into program design?
Once the block is laid out, dictate any session out loud. Relay parses sets, reps, load, tempo and RPE into a structured workout in seconds, ready to drop onto a training day.
Does Relay have an API or an MCP server?
Relay ships an MCP server, so Claude, ChatGPT and other AI apps can look up an athlete, write a session or progress a block directly in your account. Setup takes about two minutes and needs no API key. Club & Academy adds API export for organisations that need the raw data in their own systems. The setup guide has the steps.
