not by feel.
MesoFoundry Strength plans a mesocycle, ramps the intensity week over week, and hands you the exact weight and reps for every set — then adjusts from what you actually lifted.

STRENGTH
The problem
Logging isn't a plan.
Most training apps are a nicer spreadsheet — a record of what already happened. The hard part isn't remembering last week. It's deciding this one.
Log only
A tracker remembers what you lifted. It never decides what you lift next.
Blank sets
You get an empty field and guess the weight, so every session drifts a little.
Too late
Volume creeps and intensity slips, and you find out you overreached a week late.
A block that heats, then quenches.
Every mesocycle runs the same arc: intensity climbs for weeks as reps in reserve fall toward zero, then a deload cools things down before the next block. The engine draws that arc and holds you to it — it's the heart of Premium.
RIR 3 Week 1
RIR 2 Week 2
RIR 1 Week 3
RIR 0 Week 4
Deload Week 5
Effort that climbs
Reps in reserve step down week by week — from comfortable to near-failure — so each session asks for a little more than the last.
Last week sets this week
What you actually lifted decides the next prescription. Beat the target and it rises; miss it and it holds.
Cool down on purpose
When fatigue outpaces the gains, the block schedules a lighter week so the next one starts fresh, not fried.

From a plan to the next rep.
Builder
Build the block
Say how the block should run — hold, grow, prioritise one muscle, train classic pyramids, or go HIT with one all-out top set per lift — then pick your days and exercises. The builder writes the sets, reps, and the week-by-week ramp.
Logging
Know the day, then log against it
Every day opens with the muscles it hits and what you lifted last time. Log each set in a tap and the next one is waiting — on Premium, with the weight, reps, and RIR already prescribed.
Analysis
Read the signal
Estimated 1RM, INOL, and tonnage tell you whether a week was productive overload or too much — before it costs you a block. A Premium feature.
The block
See the whole cycle
Every week of the block laid out at once — what is done, what is next, and where the deload falls. Open the app and the next session is already waiting.
Templates
Start from a proven split
Full body, push pull legs, upper lower and more, each in a beginner, intermediate, and advanced version, plus a 4-day HIT split. Start one as your block, or clone it and make it yours.
Plates
Know what goes on the bar
Type a target weight and see exactly what goes on each side, using only the plates your gym has. Or add up the plates already on the bar.

-
Lift With Friends
Invite a friend to run the same block and compete. Each of you earns daily points from your own logged sets, and only the points are shared, never your log. A Premium feature.

Straight answers
Before you commit a block to it.
Do I need to know how to program a mesocycle?
No. Choose your days and exercises and the builder lays out the block — the days, the sets, the rep targets. On Premium, the progression engine also sets the weights, ramps the intensity week over week, and schedules the deloads, adjusting from what you actually lift. Either way, every choice it makes is yours to change.
Does it work without signal in the gym?
Yes. Everything logs on your phone offline. On Premium it syncs to your other devices when you are back online; on Free it stays on the one device.
How does the free trial work?
New accounts start on Free. Start the 14-day Premium trial in the app; it runs through the App Store or Google Play, which asks for a payment method, and then continues at $9.99/month or $59.99/year unless you turn it off in your store account before it ends. On Free you keep the builder, manual logging, your full history, and custom exercises.
Can I add my own exercises?
Yes, on any plan. Add lifts the app has never heard of alongside the more than 860 in the built-in library, and they slot into your blocks like any other exercise. Custom exercises are unlimited on Free.
Is my training data mine?
Yes. Settings → Your data exports your full history as a spreadsheet, any time, on any plan.
