Zone 2 run-row aerobic base

Advanced · 25–39 · ~40 min

A 40-minute easy run-row to grow the aerobic engine that carries you through a Hyrox. Below is a research-backed prompt for ChatGPT, Claude or Gemini, copy it, paste the reply into sweatcue, and run the whole cardio workout hands-free.

The prompt

Copy the complete prompt (it wraps the request below so the AI returns a clean, runnable session).

I'm an advanced Hyrox competitor building aerobic base. Write me a 40-minute Zone 2 run-row session. Warm-up: 5 min easy build into Zone 2. Main set: alternate 8 min easy running and 8 min easy rowing for two full cycles (about 32 min), all at Zone 2, roughly 65-75% of max HR, where I can hold a full conversation and breathe through my nose. Keep the row relaxed (stroke rate ~22-24 spm) and the run easy. Cooldown: 3 min very easy plus a few minutes of light stretching. Tell me how to use HR to stay in zone (slow down if I drift over), why pace should stay easy even though it feels too gentle, and how often per week I can repeat this.
Works with Claude, Gemini, Grok or any AI.

Why it's built this way

A large base of easy aerobic work is the foundation polarized-training models build hard sessions on top of, and it grows the aerobic capacity Hyrox demands across its full duration. The discipline here is staying easy, many athletes drift too hard and turn base sessions grey. Zone 2 is a training-intensity concept; the old 'fat-burning zone' framing is a myth and isn't the point of this session.

Who this workout is for

Built with one person in mind: Competitor blending running with functional strength stations.

  • You’re an advanced-level trainer and you want to build work capacity and conditioning.
  • You want to train with little or no equipment, this one needs none, just walk.
  • You want a single, repeatable cardio workout you can drop into your week.

Who should adapt or skip it

  • It’s low-risk for healthy adults. Scale the loads and reps to your own level rather than copying the top of every range on day one.
  • As with any new routine, check with a clinician first if you have a medical condition, are injured, pregnant, or returning from a long lay-off. This is general information, not medical advice.

What a 2-week plan looks like

A single session works best on a repeating weekly rhythm. Here’s a simple, balanced two-week block at about 5 sessions a week, on non-consecutive days so you recover between them:

MonTueWedThuFriSatSun
Week 1●●●·●●·
Week 2●●●·●●·

● This session· Rest or an easy walk

Keep session days apart where you can, and adjust for how you feel. When you paste the AI’s reply into sweatcue, each session runs hands-free with spoken cues and timers.

Run it hands-free in sweatcue

sweatcue is an AI workout dashboard: paste the AI's reply and it runs the whole session on screen and out loud, auto timers, spoken cues for every set, rest and rep, and your live numbers. The AI writes it; sweatcue runs it.
