§ 01 · Programmes

Three paths. Same engine.

01 / Programme
Size

Hypertrophy.

Muscle growth

Moderate loads, higher volume. Programmed for steady sarcoplasmic growth across 4–6 day splits. RPE keeps each lift just shy of failure.

Best for
Lifters chasing size
02 / Programme
Hybrid

Powerbuilding.

Strength + size

Heavy main lifts early, hypertrophy accessories after. For lifters who want both a bigger total and bigger arms. The honest middle path.

Best for
Lifters who want both
03 / Programme
Strength

Powerlifting.

Maximal strength

Squat, bench, deadlift periodised with accessory work. Built around your current maxes and peaking blocks. Test week lands on peak, every time.

Best for
Competitors chasing 1RM
ALL THREE INCLUDE AUTO-DELOAD, RPE-AWARE PROGRESSION, FULL OVERRIDE.
All three included · Pro
§ 02 · How it adapts

Your whole programme, in one chart.

Your programme has a shape.

RACK plots every working set across accumulation, intensification and peaking. The dashed line is intensity; the bars are volume. Deloads sit between phases. Automatic.

  • 01 Accumulation. Bigger volume, lower intensity. Build the engine. Four weeks, deload baked in.
  • 02 Intensification. Volume holds, intensity climbs. The line crests, then breathes.
  • 03 Peaking. Volume drops, weights climb. RACK times the taper to land on test week.
  • 04 The override. Cap a set, push past, swap a lift, skip a day. RACK records what happened, not what was prescribed, and recalibrates from there.

§ 03 · Why RACK

Three things most logs get wrong. We didn't.

01 / Programme-aware

It knows what week you're in.

RACK reads your block (accumulation, intensification, peak) and adjusts targets each session. Deloads land where they should. Every wave ends on a max.

02 / RPE-honest

Felt heavier than it looked?

Log RPE per set. RACK weighs your last weeks of effort, not just bar weight, when it picks what's next.

03 / Yours to override

Nothing is locked.

Cap a set, swap a lift, push past prescription, skip a day. RACK records what happened, not what was supposed to. Your log, your truth.

§ 06 · FAQ

Honest answers. Same as the log.

Q · 01What if I miss a session?+
RACK keeps planning from where you are, not where you should have been. No make-up sessions, no penalty volume. The streak counter on the dashboard resets after 8 days idle. That's a number, not a penalty.
Q · 02I don't know my 1RM. Can I still start?+
Yes. Skip the inputs screen entirely. RACK starts you conservative and recalibrates from your logged sets each week. You don't need a number on day one.
Q · 03Can I run my own programme?+
Two paths. On Pro, RACK plans for you, but every prescription is editable on the fly: cap a set, push past, swap a lift, skip a day. On Freestyle, you pick every lift, every session, no programme. Authoring a custom periodised block from scratch isn't a feature today.
Q · 04Where does my data live?+
On your phone first, in the cloud second. If you cancel Pro your logged sets stay. Freestyle keeps working, free, forever. Pro features get a 14-day grace window after expiry before they lock.
Q · 05Will it work in a basement gym with no signal?+
Yes. The whole app is offline-first. Log every set in a Faraday cage if you want. It syncs when you walk back upstairs.
Q · 06Is this just for powerlifters?+
No. RACK has three programme archetypes: powerlifting, hypertrophy, powerbuilding. Each gets its own filler pool, rep ranges, and progression bands. The chart up top happens to show a powerlifting example.
