How Apex builds and adjusts your training plan

Setup takes one sitting. You choose your sport and goal, pick the race and its date, say which days of the week you can train and add a recent race result if you have one. Apex shows a preview of the plan before you create an account.

A recent result matters because it sets your training paces. Without one, sessions are described by effort so you can start without testing.

The structure is decided by rules I wrote into the plan engine: how many weeks the block runs, how those weeks divide into base, build, peak and taper, how many hard sessions a week you can absorb and how many minutes each week should hold. The same inputs always produce the same structure.

Those rules follow published training models: Friel’s phase model, Daniels’ limits on quality work, Seiler’s polarized distribution and Gabbett’s limits on how fast training load should rise. Language software writes the session descriptions you read. It does not choose your training.

• A taper is always planned before your race.
• Hard sessions are capped for your level, with easy days between them.
• Weekly time rises gradually and steps back for recovery.

Tap “Can’t do this session” and say why. One ordinary miss, such as no time or travel, is recorded and the plan stays as it is: a single missed workout is not a debt to repay. Illness, injury or a second miss in the same week updates the plan straight away.

After an update, Today shows a plan note that lists which workouts changed, so you never have to guess what is different.

Three inputs: the sessions you complete, a short daily check-in (energy, soreness, sleep and motivation) and any health note you add. A low check-in offers to adjust the plan; it does not change it behind your back.

Apex also keeps a simple load model of fitness, fatigue and form from your recorded training. It is context for your decisions. It does not establish that you are ready to race.

One session, with its purpose, its planned duration and its steps. A morning briefing sums up the day when one is available, and early in the week a recap looks back at the last one. If the numbers get in the way, “Hide training numbers” leaves only the instructions.

Apex is software. It does not replace a medical professional, and it is not personal coaching: nobody reviews your individual week unless you choose 1:1 coaching, which is a separate service from $250 every four weeks.
