Trimester-by-trimester pregnancy plan (12 weeks)
Beginner · 25–39 · 12-week plan
A 12-week strength-plus-cardio plan that adapts week by week as your pregnancy progresses. Below is a research-backed prompt for ChatGPT, Claude or Gemini, copy it, paste the reply into sweatcue, and run the whole conditioning workout hands-free.
Session at a glance
This is how sweatcue structures the session once you paste it in, timed blocks with auto-starting rest and spoken cues. Figures are read from the prompt itself.

Why it's built this way
Guidelines support roughly 150 minutes of moderate weekly activity across pregnancy for those without contraindications, combining aerobic and strength work, with positional and intensity modifications as the pregnancy progresses. The weekly structure and progression logic come from general training evidence (frequency and modest volume drive results; effort can stay submaximal), not pregnancy-specific trials. This is a template to take to your provider, not medical advice, clearance and ongoing check-ins are essential.

Who this plan is for
Built with one person in mind: Expecting and active, low-impact, trimester-appropriate strength and cardio.
- You’re a beginner-level trainer and you want a balanced, sustainable routine.
- You have access to the kit it calls for: dumbbells, bike, a chair / support.
- You want a structured, progressing plan rather than a one-off session.
- You’re pregnant and cleared to exercise, and want work that’s tailored to that.
Who should adapt or skip it
- This is written for pregnancy, but every pregnancy is different, get your midwife or doctor’s OK first, and stop for bleeding, dizziness, contractions or pain.
- The jumping and high-impact work isn’t ideal if you’re pregnant, managing a heart condition, or nursing a knee, hip or ankle issue, swap in the low-impact variations or choose a steady session instead.
- If you’re at higher fall risk, do the standing work beside a wall or sturdy chair, and clear new exercise with your doctor if you have heart, joint or balance conditions.
What a 2-week plan looks like
This is a multi-week plan that progresses as you go, the AI builds the later weeks harder. Here’s the rhythm of the opening fortnight, at about 3 sessions a week:
| Mon | Tue | Wed | Thu | Fri | Sat | Sun | |
|---|---|---|---|---|---|---|---|
| Week 1 | ● | · | ● | · | ● | · | · |
| Week 2 | ● | · | ● | · | ● | · | · |
● This session· Rest, a walk, or light mobility
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.
