If you are actively trying to conceive, odds are you’ve wondered at some point if your exercise routine was helping or hindering your chances of pregnancy. Do you keep active? Do you take it easy? Is running off limits during your fertile window?
The short answer: For most women, there are no unsafe exercises during ovulation and implantation. In fact, exercising during your fertile window is good for you. It’s more about understanding which movement is beneficial to your body during this time and what you should take it easy on.
Lets discuss.
What Actually Happens During Ovulation and Implantation?
Ok, before we share our workouts let’s review what’s going on in your body:
- Ovulation: Around the middle of your cycle, your ovary releases an egg which makes its way down your fallopian tube. This is when you are most fertile and can easily become pregnant. This typically gives you a 12-24 window for the egg to be fertilized though sperm can live up to five days.
- Implantation: During your luteal phase (6-12 days after ovulation) the fertilized egg will travel to your uterus and attach itself to the lining of your uterus. For most people, this is referred to as the dreaded “two week wait.”
We don’t exercise because we’re scared that we will somehow jostle the baby out. Remember the uterus is a closed muscular cavity. The embryo does not have anywhere else to go but deep inside the uterus where it is tightly secured. Normal daily activities will not disturb the implantation of a fertilized egg.
Pregnancy Yoga Classes too hard can cause issues however. A study in the journal Fertility and Sterility reported that the more women exercised the shorter their luteal phase became. This means there is less time for the uterine wall to build up. The ACOG suggests pregnant women trying to conceive get at least 150 minutes of moderate exercise each week. They do not recommend exercising at a high intensity while trying to conceive.
Why Exercise Matters When You’re Trying to Conceive
Moving your body regularly, at a moderate pace, supports several things that directly affect fertility:
- It helps maintain a healthy weight, which matters because being overweight or underweight can both disrupt ovulation
- It improves blood circulation to reproductive organs
- It lowers cortisol, the stress hormone that can interfere with progesterone production
- It supports insulin sensitivity, which is especially important for women with PCOS
In a large prospective cohort study involving >17,000 women, researchers found that women who practiced five or more healthy lifestyle factors including at least 30 minutes exercise daily had a 69% lower risk of infertility related to ovulatory disorders compared to women who didn’t. That’s significant folks.
You’re not trying to go all out every time you work out. You’re trying to keep moving and maintain your body in a relaxed supported state while refraining from things that send cortisol skyrocketing or drain your resources.
7 Safe Exercises During Ovulation and Implantation
Here are the safe yoga poses during pregnancy that are well-supported by research and commonly recommended by reproductive health professionals during the ovulation and implantation window.
1. Walking
Walking is probably the most underappreciated fertility-friendly exercise out there. It improves circulation, lowers stress hormones, maintains a healthy weight, and you don’t need any equipment or a gym membership to do it.
For women whose BMI is on the higher side, a brisk 30 to 40 minute walk daily can help regulate hormone cycles. Even if you’re at a healthy weight, a daily walk during your two-week wait is a low-stakes way to stay active without putting any strain on your body.
Aim for a comfortable pace where you can hold a conversation. No need to power-walk or add inclines unless that’s already part of your normal routine.
2. Prenatal-Style Yoga
Yoga is one of the most recommended movement practices during the conception phase, and for good reason. Gentle yoga helps reduce stress, improves pelvic circulation, releases tension in the hip flexors and lower back, and supports nervous system regulation.
Fertility-focused yoga sequences often include poses like supported bridge, reclined butterfly, legs-up-the-wall, and cat-cow, all of which promote relaxation and blood flow to the pelvic region without any high-impact stress on the body.
Avoid hot yoga during this phase. Heat-based practices raise core body temperature, which isn’t ideal when you’re in the implantation window.
At Mom’s Preg Ladder, prenatal yoga classes are designed to be trimester-specific, but the gentle principles behind these classes are equally relevant for women in the pre-conception phase who want to move their bodies in a supported, intentional way.
3. Swimming
Swimming is one of the best full-body workouts you can do when you’re trying to conceive. The water supports your body weight, eliminates impact stress on your joints, keeps your core temperature regulated, and still gives you a solid cardiovascular workout.
Even a gentle 30-minute swim improves blood flow throughout the body, including to the uterus and ovaries, without spiking your heart rate into a zone that could stress your system.
If you’re already a regular swimmer, keep going. Just avoid high-intensity interval sets during the implantation window. Lap swimming at a steady, comfortable pace is the sweet spot.
4. Pilates
Pilates is low-impact, controlled, and places a strong focus on core and pelvic floor strength. Both of those things matter for conception and for pregnancy itself.
A healthy pelvic floor supports better blood flow to the uterus and improves the structural support around the reproductive organs. Pilates exercises done at moderate intensity also improve posture and body awareness, which becomes increasingly useful as your body changes in early pregnancy.
Stick to mat-based Pilates with modifications that avoid deep twists or heavy abdominal compression. If you go to a class, let the instructor know you’re in your two-week wait so they can suggest appropriate variations.
5. Light Strength Training
You don’t have to drop your weights entirely when you’re trying to conceive. Moderate resistance training, done a few times per week, supports muscle mass, improves insulin sensitivity, and helps maintain hormonal balance.
The word “moderate” is doing a lot of work here. This means avoiding heavy lifts to failure, breath-holding (Valsalva maneuver), and exercises that put significant downward pressure on the pelvic floor. Think lighter weights, controlled movements, and rest between sets.
Bodyweight exercises like squats, glute bridges, modified push-ups, and resistance band work are all good options during the ovulation and implantation period.
6. Stationary Cycling
Cycling at a low to moderate pace on a stationary bike is a joint-friendly cardio option that keeps your heart rate in a safe range without any of the jarring impact that comes from running or jumping.
The stationary format also means no outdoor variables like uneven terrain or sudden changes in pace. You’re fully in control of the intensity. Keep the resistance moderate, stay seated rather than standing up on the pedals, and keep sessions to around 30 to 45 minutes.
Avoid spin classes with very high intensity intervals or classes that have you standing and pushing to your max. Those are better suited to non-conception phases of your cycle.
7. Diaphragmatic Breathing and Relaxation Exercises
This one doesn’t look like traditional “exercise,” but it might be the most fertility-supportive practice on this list. Controlled breathing exercises directly lower cortisol, activate the parasympathetic nervous system, and bring your body into a state of calm that actually supports progesterone production during the luteal phase.
Deep diaphragmatic breathing, box breathing (inhale 4 counts, hold 4, exhale 4, hold 4), and guided body scans are all practices backed by evidence for stress reduction. High stress during the two-week wait is real, and chronic cortisol elevation can interfere with the hormonal conditions needed for implantation.
Even 10 minutes of intentional breathwork daily during the implantation window can make a difference, both physiologically and psychologically.
Exercises to Avoid During the Implantation Window
Knowing what not to do is just as useful. Here’s what to skip or scale back during the two-week wait and early symptoms before pregnancy
- High-intensity interval training (HIIT): These sessions spike cortisol and can deplete energy reserves quickly
- Long-distance running or endurance training: Sessions exceeding 60 minutes of vigorous activity daily have been linked to ovulatory dysfunction
- Hot yoga or sauna workouts: Elevated core body temperature is not ideal during implantation
- Heavy powerlifting: Extreme abdominal pressure and pelvic floor strain aren’t supportive during this phase
- Starting a brand new intense exercise program: This isn’t the time to dramatically change your activity level. Continue what you’re already doing, just at a moderate pace.
A Note on Individual Differences
Fitness needs will vary depending on the individual. A high-performance runner who trains several times a day is going to receive different recommendations than someone who is just getting started with exercise. A woman with PCOS will have different needs than someone who cycles regularly.
However, when you look at the research as a whole, it points in one direction: moderate, consistent exercise is beneficial to fertility in most women and too much high-intensity training can be detrimental to your fertility goals. Moderation is relative to your starting point however.
If you are working with a fertility clinic, undergoing IVF, or IUI, always consult your doctor first if you plan to continue any exercise regimen (always ask before embryo transfer). Personal Training services and Pre-Conception Classes are available through Mom’s Preg Ladder for women who desire that extra layer of individualized support and medical consultation from a certified pregnancy health coach instead of general one size fits all information that may or may not apply to you.

FAQs
Can I exercise during ovulation when trying to conceive?
Yes, exercising during ovulation is safe for most women. Moderate activity, like walking, yoga, or swimming, supports healthy hormone levels and blood circulation without interfering with the release or fertilization of an egg. Just avoid pushing into very high-intensity exercise during this time.
Does exercise affect implantation of a fertilized egg?
Normal, moderate exercise does not prevent implantation. The uterus holds the fertilized egg firmly within its walls; it cannot be “shaken loose” by movement. What can affect implantation is excessively intense exercise, which may shorten the luteal phase and reduce time for the uterine lining to thicken.
How much exercise is safe during the two-week wait?
The American College of Obstetrics and Gynecology recommends at least 150 minutes of moderate activity per week for women trying to conceive. During the two-week wait, aim for sessions of 30 to 45 minutes at a comfortable, conversational pace. Avoid vigorous workouts exceeding 60 minutes daily.
Is yoga good for fertility and implantation?
Gentle yoga is widely recommended during the ovulation and implantation phase. It reduces stress hormones, improves pelvic blood flow, and supports nervous system relaxation. Avoid hot yoga and deep abdominal compressions, but standard gentle or restorative yoga is considered beneficial for women trying to conceive.
Should I stop exercising completely after ovulation?
No, stopping exercise entirely is not necessary or recommended. Continuing moderate activity after ovulation actually supports fertility by keeping stress low and circulation healthy. The goal is to maintain your regular routine at a moderate intensity rather than stopping or suddenly increasing activity during the luteal phase.
