Phaserr is a program builder for strength and conditioning coaches.

Most coaches keep serious programming in Google Sheets: blocks, phases, loads off percentages of 1RM. An athlete hits a new max and the sheet gets rebuilt by hand, cell by cell. Phaserr does the math and the delivery, and never writes the program. That part stays the coach's.

How it works

Describe a training block and AI drafts it from your own exercise library, your progression style and your athlete's real numbers. It is a draft, your way. You adjust it, and from then on the math holds: log a new max and every percentage downstream recalculates on its own.

Send the finished program by one link to your athlete's phone. No account for them, nothing to install. Or export a PDF.

What is included

  • Linear, step and undulating progressions
  • Loads from %1RM or a training max, warm-up ramps calculated automatically
  • 1000+ exercise library, supersets, circuits, reusable block templates
  • Unlimited athletes and programs in one place
  • Per-athlete tracking: completed and skipped sessions, underperformed lifts week over week
  • Gyms and organisations get multi-coach seats, shared rosters and libraries

Built for powerlifting, weightlifting and any sport with strength training. Free for individual coaches, AI features included.

Questions & Answers

As answered by people managing Runtastic and Phaserr.

What makes your product unique?

Phaserr's answer:

Most AI fitness tools write the program for you. Phaserr does the opposite: AI drafts a training block in seconds, and then the coach edits, reshapes and approves it. The software never publishes a program on its own โ€” the coach stays the author, and the athlete's plan still carries their name and their thinking.

That one rule shapes everything else: every AI output lands in an editable block, not a locked plan.

Why should a person choose your product over its competitors?

Phaserr's answer:

Two reasons, depending on what you're leaving behind.

If you're coming from a spreadsheet: you get real structure โ€” multi-week blocks, sets, reps, load schemes, progressions โ€” and your athletes open the session on their phone instead of squinting at a shared sheet or a PDF.

If you're comparing against other coaching platforms: most of them either bury programming under billing and CRM features, or hand the programming over to AI entirely. Phaserr is built around the block builder, and the AI is a drafting assistant that you edit โ€” not an autopilot. Free for individual coaches, AI included.

How would you describe the primary audience of your product?

Phaserr's answer:

Independent strength and conditioning coaches and personal trainers who write their own programs โ€” the ones currently running everything out of Google Sheets or Excel and sending PDFs.

Typically a solo coach or a small team with a handful to a few dozen athletes, who cares about how the block is structured and doesn't want a platform making training decisions for them. Not gyms looking for billing and membership software, and not athletes looking for a workout app.

What's the story behind your product?

Phaserr's answer:

We're not coaches โ€” that's the honest starting point. One of us is a designer, the other an engineer. We kept seeing the same thing: skilled coaches doing genuinely expert work, then losing hours to spreadsheet mechanics and PDF exports.

Because we're not coaches, we made a rule we won't break: the software never writes the program. It can draft, structure and speed things up, but the training decisions stay with the person who is qualified to make them. Phaserr is being built in the open with the coaches who use it โ€” we ship, we listen, we fix.
