# CrossFit training program: the strength and engine around the workouts

> Class gives you a different workout every day, which is the point and also the problem: nothing in it progresses on a schedule. The strength, the engine and the skills are what a program is for.

## The short answer

For a CrossFit athlete, phase.fitness plans the parts that need a calendar. Strength runs as a real block — squat, press, pull and an olympic variant progressed over four weeks rather than reset every session. Conditioning is split by the hybrid-fitness document into genuinely easy aerobic work and a small number of hard intervals, which is the split that is usually missing when every session is a metcon. Gymnastics skills — muscle-up, handstand push-up, pistol — run on the phase.fitness calisthenics roadmaps with sets and holds prescribed. Class sessions sit in the week as the hard days they are, and the plan orders itself around them.

## What class cannot do

Constantly varied is a virtue for general preparedness and a problem for any single quality. A squat that appears when it appears does not follow a progression, and an engine built entirely out of hard mixed-modal work has no easy end. The hybrid-fitness document phase.fitness reads is direct about both: strength needs a block with a plan, and the aerobic base needs volume at an intensity low enough to accumulate.

So this program does not replace your classes. It writes the strength block, the aerobic work and the skill roadmap, and treats the classes you attend as the hard sessions they are when it orders the week.

## Three hard days, and the rest genuinely easy

The commonest pattern in a box is five days that are all somewhere between hard and very hard, which is the one distribution the evidence does not support. phase.fitness caps the genuinely hard sessions — heavy strength, hard intervals, a competition-style workout — at about three a week, and writes the remainder as easy aerobic work or skill practice.

Olympic lifting is programmed from the weightlifting document as technique under manageable load, not as a conditioning tool. A snatch for time is a sport; a snatch for a program is a skill with a percentage.

## Can you run a real strength block alongside CrossFit classes?

Yes, and it is most of what phase.fitness adds. Squat, press, pull and an olympic variant are progressed across four weeks instead of being reset by whatever the class board says, and the classes sit in the week as the hard days they are, with the plan ordered around them.

## How much easy aerobic work does a CrossFit athlete need?

More than most weeks contain. phase.fitness splits conditioning the way the hybrid-fitness document does — genuinely easy aerobic work, like a 50-minute row or bike at nasal-breathing pace, plus a small number of hard intervals — which is the split that disappears when every session is a metcon.

## What phase.fitness builds

| Phase | Weeks | Job | Band |
|---|---|---|---|
| Base and positions | 4 | Aerobic volume, strength technique, skill prerequisites | Strength 4 × 6 at RPE 7; 2 easy aerobic sessions of 40–60 min; skills 2 ×/week |
| Build | 4 | Load climbs, intervals appear | Strength 5 × 3–5 at RPE 8; 1 interval session; skill volume up; hard days capped at 3 |
| Sharpen | 3–4 | Test pieces, then back off | Singles at RPE 8–9, one benchmark workout a week, deload in the final week |

## A sample week

| Day | Modality | Session |
|---|---|---|
| Mon | Strength | Back squat 5 × 3 at RPE 8, push press 4 × 5, weighted pull-up 4 × 5, trunk work |
| Tue | Cardio | Zone 2 row or bike, 50 min, nasal-breathing pace throughout |
| Wed | Calisthenics | Muscle-up roadmap step 4 × 4, handstand push-up progression 4 × 5, hollow holds |
| Thu | Strength | Snatch technique 6 × 2 at 70%, front squat 4 × 4, Romanian deadlift 3 × 8 |
| Fri | Cardio | Intervals: 6 × 500 m row at 2 km pace, 2 min easy between |
| Sat | Cardio | Class or a benchmark workout, treated as the hard session it is |
| Sun | Rest | — |

## How it adapts when a phase ends

phase.fitness reads the barbell work back from Hevy or Liftosaur and the conditioning from Garmin or Intervals.icu, and counts how many sessions in the phase were genuinely hard. Garmin activities are read only if you allow it. If the count ran over three a week — usually because the classes were harder than planned — the next phase takes a hard session out rather than adding volume. Where the easy aerobic work kept getting skipped, it gets shorter and earlier rather than longer.

## Where the sessions go

- **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.
- **Intervals.icu** — Cardio sessions go out with intervals and zones intact; completed sessions, HRV and load come back.
- **Liftosaur** — Strength programs are pushed as Liftoscript; workout history comes back.
- **Calisthenics sessions** — run in the phase.fitness built-in player, with the hold timer and the progression step on screen.

## What phase.fitness does not do here

phase.fitness does not write your daily workout of the day, and it is not affiliated with CrossFit, LLC. It plans the strength, the aerobic work and the skills around the classes you already do — if you want a metcon generated each morning, this is not that.

## Frequently asked questions

### Does phase.fitness replace my CrossFit classes?

No. phase.fitness plans the strength block, the aerobic work and the gymnastics roadmap, and treats your classes as the hard sessions they are when it orders the week. The class stays where it is; the plan arranges itself around it.

### How many hard sessions should a week have?

About three. phase.fitness caps genuinely hard work — heavy strength, hard intervals, a benchmark workout — at roughly three a week and writes the rest as easy aerobic or skill work, which is the distribution most box weeks are missing.

### How are the gymnastics skills programmed?

On the phase.fitness calisthenics roadmaps. An assessment places you on the muscle-up, handstand push-up or pistol progression, and the sessions prescribe the step, sets and rest, run in the built-in player without spending AI credits.

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

Gymnastics is a third of the sport, so it is programmed rather than practised: muscle-up, handstand push-up and pistol run on the phase.fitness roadmaps with sets, holds and rest prescribed, in the built-in player.

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.
