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
Built for powerlifting, weightlifting and any sport with strength training. Free for individual coaches, AI features included.
gpx.studio PhaserrHikers, cyclists, and outdoor enthusiasts who need to plan routes, view terrain elevation, or edit GPX files; users looking for a versatile and easy-to-use GPX file editor and viewer.
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.
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.
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.
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.

Thanks, now I can begin using https://gpx.studio. - Source: Hacker News / almost 3 years ago
I record my cycle rides with an app, then I download them as .gpx to combine into one map later so I can keep track of them. The problem is my GPS is slightly inaccurate, so the lines are not exactly on the road, which looks messy. The only way I have found to fix this is to use a snap to grid tool from OS Maps or gpx.studio (both use OSM data), but I have to individually move each point to get them to all snap...

Usually I plan my trips with gpx.studio, but now gpx.studio tells me that parts of ev3 are not paved, where as it looks paved on street view. Source: about 3 years ago
Or you can use tools like this to create your own gpx files. Or even the one build in in garmin connect. Source: about 3 years ago
