Sound Familiar?

😤 Athletes constantly asking "what weight do I use?" and holding up the line
⏱️ 30 athletes, 45 minutes, and half of them don't know their weights
🤷 Kids lifting random weights because they lost their card or forgot their numbers
🔁 Repeating warmup progressions to every single athlete

There's a Better Way

Put the entire 5/3/1 program in every athlete's pocket. They always know their weights, and you get your time back.

Ready to Lift

📱Athletes enter their maxes once. The app calculates every working set, warmup, and supplemental lift automatically. No more math at the rack.

They Keep It Forever

🎓When athletes graduate, their training history goes with them. Set them up for a lifetime of strength training — not just four years.

Plate Calculator

🔢Shows exactly which plates to load. Even your freshmen will load the bar correctly the first time.

Works Offline

📴No gym WiFi? No problem. The app works completely offline — perfect for weight rooms with spotty signal.

Rest Timers

⏱️Athletes stay on schedule with built-in timers. Keeps the weight room moving without you playing timekeeper.

Automatic Progression

📈Training maxes update each cycle automatically. Athletes see their progress and stay motivated all season.
