Coach Orion lives on your iPhone. It reads every set you log, factors in last night's recovery, and tells you exactly what to do next: heavier, hold, add a rep, or back off.
Log a set; within seconds Coach Orion tells you whether to go heavier, hold, add a rep, or back off. Driven by a deterministic progression engine, not vibes.
With permission, Coach Orion reads HRV, resting heart rate, and sleep from Apple Health and titrates today's volume to match. Pulling back when you're run down, pushing when you're primed.
Volume landmarks, autoregulation, planned deloads. The principles strength researchers spent decades converging on, running quietly behind every set. You train; Coach Orion does the thinking.
Coach Orion builds you a full training block from your goals, experience, and the equipment you actually own, then adapts it as you train. Works with just dumbbells and floor space, and scales up to a full rack.
Tell Coach Orion your goal, weekly availability, experience, and what's in your gym, from just dumbbells and floor space to a full barbell and rack. Coach Orion builds your training block in minutes.
Weight, reps, and reps in reserve. That's it. No stopwatch, no chart. The methodology lives behind the screen.
Set by set RIR, your weekly volume trend, soreness, and last night's recovery, all combined into a single coaching call.
Load goes up, volume shifts toward what's lagging, deloads land when you've earned one. Week 4 doesn't look like week 1.
After every session, Coach Orion writes you a verdict: what the numbers actually mean, what to take from today, and what to do next. Tap a sample.
With your permission, Coach Orion reads HRV, resting heart rate, and sleep from Apple Health every morning and adjusts the day's training before you tap Start.
Most apps run the same calendar plan whether you slept seven hours or four. Coach Orion treats your readiness as input, not noise. Pulling volume when you're depleted, leaning in when you're primed.
You stay in the productive band more often, which is how progress compounds. Push when it counts; back off before it costs.
The principles aren't ours. They're the body of evidence the hypertrophy community has converged on over the last decade. Coach Orion is the system that runs them for you.
Load and reps climb when you're ready, not on a fixed schedule. Your last set's RIR is the gate.
Four-week blocks accumulate volume to a peak, then deload to consolidate gains. Then start again at a higher floor.
Each muscle gets enough weekly sets to grow (MEV) but stays below the volume it can't recover from (MAV).
Reps in reserve replaces “as many as possible.” Hard but not redlined, every set, every session.
The deload is built in, typically week 4. You don't have to earn rest by getting hurt.
Pre-session soreness check nudges that muscle's volume up or down for the week. Quiet feedback, loud impact.
These principles are popularized by educators in the strength science community. Coach Orion is an independent product, not affiliated with, endorsed by, or in partnership with any of them. The credit for the science belongs to the researchers; the credit for nailing your top set on Thursday belongs to you.
Volume climbs through the block. More sets, more reps, more total work, until the planned deload, where load and volume drop so your body can consolidate the work you put in.
That's what builds. Most lifters never get there because they never get out of the same week.
