Mesocycle
A training block of, typically, 3 to 6 weeks with a single focus (hypertrophy, strength, endurance), almost always ending with a deload week. It is the planning unit you spend most of your time in: you set the goal, distribute the volume, and progress the load week to week.
In practice
A 5-week hypertrophy mesocycle: four weeks raising set volume week by week (from ~12 to ~18 sets per muscle group) and a fifth deload week at half. By the end you shed the fatigue and are ready for the next block.
How to use it in a plan
Pick one focus for the block (hypertrophy, strength or endurance), set the starting volume and how you progress it, and almost always close with a deload. It is the unit you spend most of your planning time in inside NoteFit.
Where the block lives in NoteFit
A plan descends through four levels: the macrocycle holds the season, the mesocycle holds the block, the microcycle holds the week and the workouts hold the exercises. The mesocycle is the middle level, and it is where the decisions that hold for several weeks in a row live — the written goal, the title, the start date and the end date.
It is also the only level that carries the calorie band, with a minimum and a maximum. That says more about the model than it looks: nutrition is not tied to the day or to the season, it is tied to the block, because that is the scale at which changing it makes sense. Change your goal and you change block, and the band moves with it.
What moves inside the block, and what stays put
Exercise selection is the part worth leaving alone. The block exists to answer one question — did the load go up? — and that question only has an answer if the lift is the same from week to week. Swapping the flat bench for the incline halfway through is not a variation, it is erasing the measurement in the middle of taking it.
What moves is volume and load. NoteFit ships a default weekly goal of 12 sets for legs, glutes, chest and back, and 4 for shoulders, triceps, biceps and abs; that is the starting point the panel shows, not a prescription. Climbing from there across the block, one muscle at a time, is what gives the deload something to unload.
A mesocycle is a plan, not a log
This is worth saying plainly, because it changes how you use the tool: NoteFit has no concept of a completed session. There is nowhere to tick that Tuesday actually happened, and no field separating what was written from what was done. The block holds the intent, and that is all it holds.
In practice, the weekly volume panel counts the sets you planned, not the ones you lifted. If the week went at half pace, the number does not know. Anyone who wants that difference has to keep it somewhere else — and it is better to learn this in your second block than in your tenth, after deciding a lot while looking at a number that measured something else.
FAQ
How many weeks should a mesocycle be?
Typically 3 to 6. Too short and there is no time to accumulate adaptation; too long and fatigue outruns progress before the deload.
Can I swap exercises mid-mesocycle?
Better not. The point is to progress the same lifts across the block so you can see the load climb; swapping everything halfway erases that measurement. Change in the next block.
What is the difference between a mesocycle and a microcycle?
The mesocycle is the multi-week block with one goal; the microcycle is the week inside it. A mesocycle contains several microcycles, and it is on the microcycle that the workouts hang.
Do I have to finish one block before starting the next?
No. Each block carries its own start and end dates, and nothing stops them overlapping or leaving a few days with none. What matters is that each one has a single goal — otherwise it stops answering any question.
What is the best goal for a first block?
Whatever you can measure. Hypertrophy with a modest starting volume is the easiest to judge after five weeks, because the signal is sets and loads you are already writing down.
