# phase.fitness for coming back after an injury

> Coming back is not the old program at half the weight. It is the same patterns loaded differently, progressed slowly enough that the tissue keeps up — and a plan that responds when a session goes badly instead of pretending it did not.

## The short answer

You tell phase.fitness what hurts, and it becomes a constraint the generator works around rather than a reason to stop. The pain-and-return document's rule is that the movement pattern stays and the range or the tool changes: a trap bar instead of a straight bar, a floor press instead of a bench, a leg press through the range that is available. Load is rebuilt from what does not hurt, progressions run longer than usual because connective tissue adapts more slowly than muscle, and every phase is written from the sessions you actually completed — so a bad fortnight changes the next block instead of being carried as a debt.

## How do you get back into training after an injury?

By keeping the movement and changing the tool or the range. phase.fitness turns what hurts into a constraint: a trap bar instead of a straight bar, a floor press instead of a bench, a leg press through the range you have. Load is rebuilt from what does not hurt and progressions run longer than usual. Clearing an injury stays with your clinician.

## Can a training app adapt to an injury?

phase.fitness can work around one: you declare what hurts and what you cannot do in your profile, and the generator treats it as a constraint on exercise selection, swapping the implement or the range while keeping the hinge, squat, push and pull. Each next phase is written from the sessions you completed, so missed weeks shrink the block instead of piling up.

## Your week, honestly

- **The old program does not fit any more.** The pattern that hurts is in it three times a week, and the only options on offer are do it anyway or skip the day.
- **Progress is a guess.** Nobody tells you how fast to add load when the limit is a tissue rather than a muscle, so it goes up too fast and then all the way back to zero.
- **A bad week wrecks the plan.** Two sessions skipped and the schedule is a week of debt you are supposed to repay, which is how the second flare-up happens.

## What phase.fitness does about it

- **Injuries and exclusions in the profile** — You declare what hurts and what you cannot do. The generator treats them as constraints on exercise selection in every phase it writes, not as a note you have to remember. (https://www.phase.fitness/features)
- **The pattern stays, the tool changes** — The substitution rules swap the implement or the range and keep the movement — hinge, squat, push, pull — so the program is still a program.
- **Longer progressions, on purpose** — Load climbs more slowly than in a normal block, because the limiting tissue adapts more slowly than the muscle around it.
- **The next phase is written from the real one** — Sessions you skipped are read as information. Two missed weeks and the next block is smaller, not a backlog. (https://www.phase.fitness/ai-periodization)

## Programs to start from

- [General fitness program: three days, six movement patterns](https://www.phase.fitness/training-programs/general-fitness-program) — phase.fitness writes general fitness as the document prescribes: full-body, compound-led sessions that cover the body in five movements, an aerobic dose that is not optional, and progression measured in consistency first and load second.
- [Full body, three days a week](https://www.phase.fitness/training-programs/full-body-3-day-program) — Three full-body days a week is what the frequency document recommends for the first years of lifting, and phase.fitness writes it the way it should be written: two sessions that alternate, the big patterns every time, and progression that starts session to session.
- [Dumbbell-only program, periodized](https://www.phase.fitness/training-programs/dumbbell-only-program) — A pair of dumbbells covers every movement pattern the exercise document lists, and phase.fitness writes a periodized program from them — patterns first at RPE 7, then load — instead of the same circuit until the heaviest pair runs out.
- [Strength training program for over 50](https://www.phase.fitness/training-programs/over-50-strength-program) — Almost nothing about the training changes after 50. What changes is how long it takes to recover from it, and what you lose first if you leave it out — which is power, not strength.

## The apps you already use

- **Hevy** — Strength routines are written to Hevy; logged workouts return to phase.fitness. Cardio and calisthenics do not travel here.
- **Garmin** — Write it here, train it on your Garmin: strength and cardio sessions are sent to Garmin Connect and appear on the watch, and the activities you finish come back to mark the plan done.
- **Liftosaur** — Strength programs are pushed as Liftoscript; workout history comes back.
- **Strava** — Post to Strava: the sessions you finish in phase.fitness go to your Strava feed, only the ones you choose. Nothing is imported from Strava.

## Frequently asked questions

### Will phase.fitness tell me if my injury is healed?

No. phase.fitness plans training and works around constraints you give it. It does not diagnose, it does not assess a rehab stage, and it is not a substitute for a physiotherapist who can look at the thing.

### What happens to exercises I cannot do?

They come out and the pattern stays. The phase.fitness substitution rules pick a variant you can load — trap bar for straight bar, floor press for bench — so the program keeps its shape instead of losing a whole movement.

### What if I have to stop again mid-block?

phase.fitness reads what you completed, not what was planned. A fortnight of missed sessions produces a smaller next phase, rebuilt from where you actually are — not a week of catching up.

## The only app that plans strength, cardio and calisthenics together

Bodyweight work is where load gets genuinely fine-grained: an incline push-up, a step-down, a hang held for eight seconds are loads a barbell cannot dial down to, and they are how a range is rebuilt.

Right now, phase.fitness is the only training app that writes strength, cardio and calisthenics into one periodized program — same calendar, same phases, same recovery budget.

You choose the mix. A calisthenics-only plan, a cardio-only block, strength plus cardio, or all three: the phases, the end-of-phase analysis and the sync work the same way with one modality or three.

**Why calisthenics is in the plan.** Bodyweight skill work is strength training in a different shape. Straight-arm work, levers and handstands build scapular control, tendon capacity and relative strength that barbell and machine work leave untouched, and they transfer because they are closed-chain, whole-body patterns. Treated as a modality rather than a warm-up, they get sets, holds and progressions like a squat does.

No exercise catalogue on the market contains a tuck front lever, so those sessions run in the phase.fitness built-in player; strength goes to Hevy, Liftosaur or a Garmin watch, cardio to Garmin and Intervals.icu.
