Six-layer graph. No strings.
Program. Mesocycle. Microcycle. Routine. Routine exercise. Per-set prescription. Each one is a real entity with a stable identifier — and every analytic touches the graph, not a free-text field on a workout row.
For the program runner
Your block, as a real graph.
Most apps store your block as a string — "Hypertrophy 1," "5/3/1 week 3," whatever you type. flexRep models it as Program → Mesocycle → Microcycle → Routine → exercises → per-set prescriptions. Every analytic reads from the graph. Block comparison knows what week belonged where. Stall detection knows when a deload happened. You see the inline target on every receipt row.
Where flexRep meets you.
You run blocks. You don't need the app to design them. You need the app to know which week is week three of which mesocycle, what was prescribed, what you actually did, and what changed between this block and the last one.
Prescription stamps onto every set.
When you log, the target gets stamped in. The receipt shows the delta inline — "Bench 5 × 230 · target 5 × 225 · +5." Green when you exceed, red when you miss. The number tells the truth before you read it.
Block Comparison — two mesos, side by side.
Pick any two mesocycles, two date ranges, or last-vs-prior. See the deltas: top e1RM per exercise, total volume, average RPE, fractional muscle distribution. Two taps from Insights.
Hypertrophy 1 · Mesocycle 2 · Week 5 · deload.
Every layer of the program is a real entity, indented under the one above it. The deload week reads in italics. The prescribed set shows "target 5 × 225" inline; the logged set lands underneath as a +5 green delta. Two taps from Insights opens the same view for any prior block.

Five features doing real work for you.
Out of the The Program Runner's thirty-six daily features, these are the ones that earn their seat at the rack.
Programs as a typed graph
Program → Mesocycle → Microcycle → Routine. Stamped into every set. Read by every analytic.
See itBlock Comparison
Two mesocycles, two date ranges, or last-vs-prior. Deltas on e1RM, volume, RPE, fractional muscle distribution.
See itDeload-aware stall detection
When a microcycle has the deload flag set, stall detection knows. No false positives during a planned drop.
See itInline target deltas
Every receipt row shows the prescription and the delta you put up. The +5 lands against the plan, not in a vacuum.
See itRoutine adherence chart
Stamped prescriptions become a chart. See exactly where you hit, where you came up short, where you exceeded plan.
See itHow it stacks up for someone running a real program
Boostcamp, Strong, and 5/3/1 Workout Log all approach periodization differently. flexRep's pitch is that it doesn't prescribe — it just remembers, structurally, what was prescribed.

Auto-generated programs as a service
Refusals are also features.
- We don't auto-write your program.
- We don't convert your block to a free-text label and lose the structure.
- We don't cry stall during a planned deload.
- We don't hide the graph behind a paid tier.
