Generic builders stop at sets and reps.
Most tools can't express a wave, an intensification, or a deload. Phaserr builds periodization down to the warm-up set.
The workout builder app for periodized strength programs
Build sessions with real periodization — blocks, auto-progressions, and loads that fill themselves in from %1RM or RPE. Start blank or from a template.

Turning percentages into kilos is busywork.
Every %1RM cell is a calculation you'd rather not do by hand. Set the basis and Phaserr fills the loads in.
Progressions don't program themselves.
Typing week-over-week increments by hand invites mistakes. Linear, step, and undulating progressions apply automatically.
A rigid template never fits every athlete.
Off-the-shelf plans break the moment an athlete is different. Adjust any routine and save it as your own template.
Build in blocks, not just days
Lay out mesocycles and training blocks the way you actually periodize — plan them ahead, re-order them, and keep the full history.
- Plan blocks ahead and re-order them freely
- Waves, intensifications, and deloads, not just sets
- One main lift per day or a full multi-lift session
- Keep the complete training history in view
Loads and progressions that fill themselves in
Choose %1RM, RPE, or linear, set the basis once, and the loads and warm-up ramps are calculated for you — down to every set.
- Auto-calculated %1RM and RPE loads
- Linear, step, and undulating auto-progression
- Auto-generated warm-up sets for every main lift
- Exercise-specific tracking fields from a 1300+ library
Make any program yours
Start from a built-in template or a blank block, then adjust anything — and save your version to reuse across athletes.
- Edit any routine, set, or progression
- Save your own reusable templates
- Add individual notes for each athlete
- Collections for warm-up and conditioning work
Start from a proven block, not a blank page
Built-in program templates you can load, edit, and assign in minutes — every load basis stays yours to set.

Frequently asked questions
What is a workout builder app?
It's a tool for designing structured training sessions — choosing exercises, sets, reps, and loads — and organizing them into a plan. A strength-focused builder goes further: it expresses periodization and calculates loads. Phaserr builds periodized blocks, auto-applies progressions, and turns %1RM or RPE targets into exact loads for every set.
Can Phaserr build periodized programs, not just single workouts?
Yes. Phaserr is built around mesocycles and training blocks, so you plan waves, intensifications, and deloads across weeks — not just isolated sessions. You can re-order blocks, keep the full history, and program one main lift per day or a complete multi-lift session, all within the same structure.
Does it convert percentages into actual loads?
Yes. Set the athlete's basis — 1RM or training max — and Phaserr calculates every %1RM load for you, including auto-generated warm-up ramps. You can also build by RPE or linear progression. The math that usually fills a spreadsheet happens automatically the moment you set the basis.
How many exercises are in the library?
Phaserr includes a library of over 1,300 exercises, each with its own tracking fields, plus collections for warm-up and conditioning work. You can build any session from the library and save custom routines as reusable templates, so your own programming becomes as fast to reuse as the built-in blocks.
Can I save my own templates?
Yes. Start from a built-in program template or a blank block, adjust anything — exercises, sets, progressions, notes — and save your version as a reusable template. Your templates sit alongside the built-in ones, so you can spin up a familiar block for a new athlete without rebuilding it each time.
Is the workout builder free?
Phaserr is free to use. You get the full builder — periodized blocks, auto-progressions, %-to-load calculation, and the exercise library — at no cost. Create an account to start building programs.
