A programme, not a blank notebook

Know the session. Record the truth.

A useful gym workout planner should reduce decisions without taking away control. RACK gives you a clear session, keeps logging quick on the gym floor and leaves every load, set and exercise editable.

Start with structureChoose a goal, programme style, length and schedule instead of building every session from scratch.
Log the effortRecord load, reps and RPE for each set so an easy eight is not treated like a grinder.
Keep final controlAccept or override suggestions, swap an exercise, change the work or skip a session.

Planning and logging belong together

A blank workout log is flexible but leaves every programming decision to you. A rigid template provides direction but cannot tell the difference between smooth work and a day where the prescribed load was wrong. RACK joins the two jobs: it plans the session, then responds to what you actually record.

You choose hypertrophy, powerbuilding or powerlifting, the programme length and whether sessions follow fixed weekdays or a flexible rolling queue. The app builds the structure; you can still change a load, cap or extend work, swap an exercise or move the session.

Lifting plus running

Add a separate 5K-to-marathon run plan and see both disciplines on one calendar.

How RACK knows what weight to suggest

RACK uses the load, reps and effort you record to inform later strength prescriptions. During a session it can suggest the next load. Across the programme it can recalibrate working numbers while preserving the intended shape of the block.

Visible, editable decisionsThe app does not claim to diagnose readiness or replace a coach. It shows the prescription and suggestion, and you decide what belongs in the session.

Progress without data-entry drag

The active exercise, prescribed work and rest timer stay close together. History remains available when you need context, but completing a set does not become a form-filling exercise. That matters because logging quality falls when the interface becomes work of its own.

RACK also includes a free Freestyle path for self-directed logging. Adaptive programmes are part of Pro, while the current iPhone beta is free to join through TestFlight.

Keep the habit visible

Share completed workouts with friends, compare volume, streaks, records and XP on friends-only leaderboards, then earn levels and medals as the work adds up.

Who RACK suits

  • Lifters who want programmed hypertrophy, powerbuilding or powerlifting rather than a blank log.
  • People who want to know what workout and weight comes next.
  • People who want to customise the overall plan by talking to RACK Coach.
  • Runners who also lift and want both disciplines on one calendar.

Evidence checked: A systematic review and meta-analysis supports session RPE as a valid way to quantify resistance-training intensity. RACK captures RPE at set level as one programming signal, not a diagnosis of recovery.

Strength training app questions

Does RACK write my programme?

Yes. Choose hypertrophy, powerbuilding or powerlifting, programme length and schedule. RACK creates the sessions and prescriptions, which remain editable.

How does RPE change the plan?

Load, reps and set-level RPE give the strength engine evidence about how the work went. RACK can use that evidence for the next-load suggestion and later recalibration; you keep the final say.

Can I use RACK without mobile signal?

Yes. Active strength logging is offline-first and synchronises later. An unreliable gym connection should not interrupt the workout.

Can I just log my own workouts?

Yes. Freestyle supports self-directed strength logging. Structured adaptive programmes are available through RACK Pro.
