Evidence-based, periodized training — Beta 2026

A program
that rebuilds
itself.

Periodized. Personalized. Rebuilt every six weeks. Meso writes you a program based on your goals, your equipment, and your training history — and rebuilds it as you progress. Grounded in peer-reviewed sports science, adapted set by set as you log.

meso·cycle n. a 4–8 week block of training, structured so each week progresses toward peak performance — followed by a mandatory deload.

01 / Why Meso

The difference between running a program and being the program.

Programming yourself
  • You research the literature, decide on a split, and hope you got the volume right.
  • You pick exercises that fit your equipment, your injuries, and what's actually available on the gym floor.
  • You design progression — when to add weight, when to add reps, when to back off.
  • You track volume per muscle group and try to keep it inside sane bounds.
  • You decide when you're cooked enough to need a deload — usually after you already needed it.
  • Twelve weeks later, the program ends. You start the research again.
Meso
  • Programs built from your intake: goal, injuries, equipment, recovery, frequency.
  • Weekly volume audited per muscle group against MEV/MAV/MRV — not by you.
  • Exercises sequenced by a validator: compound-first, no redundancy, equipment-aware.
  • Every movement ships with a progression scheme — linear, double, wave, or RPE.
  • Deload mandatory every 4–6 weeks. Volume drops 40–50%, automatically.
  • The plan rebuilds itself every six weeks. You show up, log sets, and train.
What you'll actually use

The program in your pocket.

Two screens you'll open every day. The Plan shows the week ahead and where today fits in the macro cycle. Today is the session itself — exercise, target weights, RPE caps, swap suggestions if anything's off.

02 / The four phases

Real periodization. Not a rotating set of PRs.

PHASE 01
Accumulation
Build the base

High volume, moderate intensity. Technique reinforcement, hypertrophy, work capacity.

Volume
HIGH
RPE
6 – 8
PHASE 02
Intensification
Load rises, sets fall

Volume tapers. Intensity climbs. The bridge between building and expressing strength.

Volume
MED
RPE
7 – 9
PHASE 03
Peak
Maximum expression

Minimum volume, maximum intensity. Singles, doubles, triples. What you've built gets tested.

Volume
LOW
RPE
8 – 10
PHASE 04
Deload
Non-negotiable

Every 4–6 weeks. Volume drops 40–50%, intensity drops, CNS recovers. Then we repeat, heavier.

Volume
−50%
RPE
5 – 6
03 / Inside the engine

Five stages. Every generation.

→ 01
Context
We pull your profile, injury history, recent RPE, and muscle priorities into a single training context.
→ 02
Pool
Per-session exercise pools filtered by your equipment, contraindications, and split.
→ 03
Select
An LLM selects and sequences exercises using your context — not a fixed template.
→ 04
Audit
A validator audits against framework rules — volume, ordering, redundancy — and retries if needed.
→ 05
Persist
Program lands in your account with every set's progression scheme pre-assigned. You train.
04 / Life happens

Rigorous programming. Flexible execution.

Equipment & Travel
Wherever you train. Whatever you have.

Two orthogonal dimensions, one program. Equipment Access is your default — Full Gym, Home / Garage, or Minimalist (dumbbells + bodyweight). Travel Mode is a boolean override that filters everything to bodyweight, anywhere. Together that's four reachable equipment states — and Meso regenerates the affected sessions for whichever combo you're on, then re-syncs your progression when you're back so you don't lose the block.

Exercise Swap
Machine taken? Swap in one tap.

Every exercise has a ranked list of alternates for the same muscle, same stimulus. Tap the movement, see equivalents filtered to the gear you have right now. Progression carries over. Session continues.

Pull-up (weighted) Lats · Vertical pull

05 / Session view

Snappy where it matters.

Set logging is optimistic, offline-tolerant, and one tap. No modals. No "are you sure." No loading spinners between your warm-up and working set.

Weights render in your preferred unit — kilograms or pounds — your call.

Next week's load isn't calculated by a fixed percentage. It's derived from how the last set actually felt.

06 / The method behind it

Built on peer-reviewed sports science.

Every rule Meso enforces — volume landmarks, RPE-based autoregulation, deload timing, stretch-biased hypertrophy, compound-first ordering — traces back to published research in exercise science.

We're a rule-based engine enforcing evidence. If a rule surprises you, we show you the paper.
