Exercise While Trying to Conceive: How to Find Your “Right Amount” Without Spiking Your Stress Load

---

Here’s what you need to know:

For most people, moderate and consistent exercise supports trying to conceive.

• There is no specific amount of exercise that’s “too much” for trying to conceive. This amount depends on your total stress load, which includes exercise, sleep, life stress, and nutrition.
• The best exercise advice for trying to conceive: focus on exercises your body can recover from today.
• If your menstrual cycle is regular, your energy levels are consistent, and your body feels good, your exercise routine may be just fine, even if it’s hard.
• If you feel depleted and/or your menstrual cycle is changing, your body may need less intense exercise and more recovery. This doesn’t mean stopping exercise entirely.
• Use a quick weekly exercise review and template to help you stay on top of your exercise without getting overwhelmed.
• If your menstrual cycle stops or becomes irregular, it’s time to talk to your doctor.

Don’t stop exercising to get pregnant. For the majority of people, moderate and consistent exercise supports trying to conceive. The actual concern with “how much exercise is too much?” lies in your total stress load, which includes exercise, sleep, life stress, and nutrition.

If you are someone who has a pretty consistent cycle, plenty of energy, and good recovery, what you are doing may actually be working for you, even if it’s a lot. If you are tired, sleeping poorly, getting sick, and experiencing changes with your cycle, what you are doing might not be working for you, and the solution is not “stop exercising,” but rather less intensity, more recovery.

A peaceful, common-sense approach:

Pick exercise that your body can recover from, this week, in the real world.

🟢 Good sleep, consistent cycle, good energy, normal appetite, consistent mood

🟡 Increasing fatigue, soreness lasting longer, irritability, cravings, sleep issues

🔴 Cycle irregularity, amenorrhea (no periods), exhausted, injuries, frequent illness

Why this question is so charged (and why most answers miss the mark)

TTC exercise advice can be confusing because most advice is given as a rule:

“Don’t exercise too hard.”
“Exercise can really help fertility.”
“Avoid stress.”

Your body doesn’t see exercise as good or bad. Your body sees exercise as a stress input. It’s what happens with that stress input that determines whether it’s good, bad, or neutral.

But something is missing from a lot of the advice: your total stress load and your capacity for recovery, also referred to as allostatic load (the ‘wear and tear’ effect of stress on the body over time).

TTC headspaces we see a lot:

The overachiever: Exercise is how you cope. And then you’re TTC and wonder: Is my training backfiring on me?
The guilt-spiral: You haven’t been exercising. And then you’re under pressure to ‘do everything perfectly’ and ‘fast’.

Either way: you don’t need punishment or permission. You need a framework.

The Framework: What is Total Stress Load (and how it affects you)

This is the framework we use at Monday because it actually reflects how the world works: your body responds to total stress load, not one thing at a time.

What is Total Stress Load?

• Training Load: Volume, Intensity, Frequency
• Sleep Debt: Duration, Quality (and Consistency)
• Life Stress: Work Stress, Anxiety, Travel, Caring
• Nutritional Stress: Under-Eating, Low Energy Availability, Dehydration, Insufficient Carbs and Protein for Training

Fertility-relevant systems in your body don’t exist in a vacuum. Your HPA Axis (your ‘stress response’ system) and reproductive hormones can be impacted by your allostatic load (your capacity for recovery) from chronic stress and under-recovery.

But what “too much exercise” really means is not “running” or “lifting.” It means:
high intensity + inadequate recovery, repeated for weeks or months, especially if combined with inadequate nutrition.

If total load exceeds your recovery capacity, the body may deprioritize reproduction.

The Stress Load Audit (2-minute self-check)

If you want to know “what should I do this week?” then this is for you. This is a weekly calibration tool, not a diagnosis.

How to score yourself (in a simple, non-judgmental way)

You score each domain on a scale from 1-5. Add your scores to find your total. If unsure, pick the higher score. When TTC, err on the side of recovery.

• Weekly training intensity/volume (1 = low, 5 = high)
• Sleep quality/duration (1 = good sleep, 5 = poor sleep)
• Perceived life stress (1 = low stress, 5 = high)
• Cycle regularity (1 = regular cycle, 5 = unpredictable/no cycle)

Here’s how to gauge your results:

• 4-8: Low load: good to continue
• 9-13: Moderate load: keep exercising, reduce intensity peaks
• 14-20: High load: take 2-4 weeks off or reduce to low cortisol/low recovery load

The goal in all this: reduced recovery demand + support for sleep and fueling (and cycling stability if applicable).

Two common TTC scenarios (and what to do next)

You will see the best results when your plan aligns with your current situation and not someone else’s.

If you’re an intense exerciser (runner/HIIT/CrossFit)

The goal here is not “stop.” It’s mitigate stress peaks and support recovery to keep your training supportive.

When you experience any of the following, your training load may be too high:

• fluctuations in menstrual cycles, fatigue, and disrupted sleep
• plateauing, irritability, and lingering muscle soreness
• injuries and illnesses

Common adjustments to try:

• dial back on the amount of HIIT (often 0-1 times per week during high-stress times)
• include true recovery days (end the day feeling better, not worse)
• make sure to fuel adequately (especially carbs around workouts)
• plan a de-load every 3-6 weeks

Keep/Change/Hold:

• Keep: submax strength training, easy cardio, mobility work, walking
• Change: amount of HIIT, amount of endurance work, late-night workouts
• Hold (temporarily): repetitive max efforts without recovery

If you haven’t been exercising (and feel behind)

You don’t have to “earn” pregnancy with intense workouts.

Your best bet for a starting point:

• Walking, gentle strength training, mobility work, cycling

Your rule for progressing:

• Add one thing at a time: duration OR intensity OR frequency.

4-week starter plan (simple)

• Week 1-2: 20-30 minutes walking 4 times per week + 2 strength workouts (15-25 minutes each)
• Weeks 3-4: Add incline or light resistance; keep one full rest day

Train for body readiness, not punishment

TTC isn’t the time to push limits. It’s a time to build up recovery capacity so you can support reproductive readiness.

Most exercise programs track steps and calories burned. We care more about what you don’t see in the plan: your stress levels and recovery patterns.
