Deciding to try for a baby brings a lot of questions, and somewhere in the mix is often this one: should I keep working out? Maybe you have heard that exercise boosts fertility. Maybe you have heard it can hurt. Both stories have some truth. This guide breaks down what the research says, what to expect, and where Shred415 fits into your journey.
The Short Answer
- Regular, moderate exercise is linked to better fertility outcomes for most people.
- Very high volumes of intense exercise may disrupt ovulation in some women.
- During active fertility treatment, many clinics recommend dialing intensity down.
- Shred415 does not offer classes designed specifically for fertility, but you control your pace, and you should check with your provider first.
Are You More Fertile If You Work Out?
Exercise can help, but it is not a magic switch. Dr. Lora Shahine’s summary of a 2019 meta-analysis found that physical activity has beneficial effects on reproductive outcomes, with the biggest benefits in people with obesity, polycystic ovary syndrome (PCOS), and insulin resistance. A more recent umbrella review of meta-analyses linked exercise to higher ovulation and pregnancy rates in women and better sperm quality in men.
The catch is that research cannot say exactly how much or how hard is ideal. Being sedentary is not a neutral choice either. The same summary notes lower fertility rates in sedentary women of normal weight.
How Does High-Intensity Exercise Affect Ovulation?
Your body reads your routine as a whole picture. Fertility clinic CCRM explains that more than an hour of vigorous exercise a day can lower the hormones that stimulate the ovaries in some women, and the risk rises with duration and intensity. The same article points to a study where women who exercised 30 minutes or more daily had a lower risk of infertility caused by ovulation disorders.
The takeaway is that the sweet spot is not the couch and not marathon training. It is consistent movement with good fueling and real recovery. Evewell notes that long stretches of excessive exercise without enough recovery or nutrition can disrupt hormones and ovulation.
What Exercises Are Safe for Women Undergoing Fertility Treatments?
This depends on your treatment, so your clinic’s guidance always wins. Tommy’s reports that being active before and during IVF appears to have no effect or a slightly positive effect on treatment success. It also notes that vigorous exercise problems with ovulation do not seem to apply when medication controls ovulation.
Safety is a separate question, though. Evewell explains that during stimulation the ovaries may be enlarged, and HIIT, heavy lifting, and intense cardio can add abdominal pressure and a small but real risk of ovarian torsion. That is why those activities are usually best avoided during treatment.
Gentler options that clinics often approve include:
- Walking
- Lighter strength work
- Yoga or stretching
- Low-impact cardio
Ask your clinic what to do around egg retrieval and embryo transfer, since guidance varies.
What Are the Best Exercise Programs to Improve Fertility?
No single program is proven to boost fertility. Research points to a balanced mix of cardio, resistance training, and recovery. The umbrella review above linked both cardio and resistance training with fertility-related benefits. Mayo Clinic also encourages stress-lowering activities like yoga and deep breathing while you try to conceive.
A simple way to think about it: walk often, strength train regularly, add something calming, and rest when your body asks for it.
How Shred415 Can Support You While Trying to Conceive
Every class alternates four 15-minute intervals between the treads and the decks, so you get cardio and strength in one class. You can read more in our blogs on hybrid training and functional training.
- You set the pace. Walkers, joggers, and runners are all welcome, so an incline walk on the treads can keep your effort moderate. Our HIIT vs steady state guide explains how the intervals work.
- Strength on the decks. Squats, lunges, and presses build muscle, and instructors offer modifications. Our class guide covers lower-impact options like Total Body Climb.
- Community and stress relief. One fertility clinic points out that exercise gives you a productive way to respond to stress during treatment, and the Shredfam makes showing up easier.
Understanding Shred415 During Fertility Treatment
Shred415 offers a high-energy, interval-based workout experience designed to help members build strength, endurance, and confidence. However, exercise needs can look different for those who are trying to conceive or undergoing fertility treatment.
- Individual needs vary: Shred415 classes are designed for general fitness rather than specifically for fertility treatment, so members may need to adapt their workouts based on their individual circumstances.
- Treatment timing matters: Certain stages of fertility treatment, particularly ovarian stimulation and the period around egg retrieval or embryo transfer, may require modifications to exercise intensity. Members should follow their fertility clinic’s guidance.
- Listen to your body: The motivating group environment can encourage members to push themselves, but taking a lower-impact option, reducing intensity, or resting when needed can be an important part of exercising safely.
If you’re undergoing fertility treatment, speak with your fertility care team about what types of exercise are appropriate for your current stage of treatment. Let your Shred415 instructor know about any exercise restrictions so they can help you explore suitable modifications.
What Can Mess Up Fertility?
Exercise is rarely the main story. According to Mayo Clinic, smoking is linked to lower fertility, heavy drinking is linked to a higher risk of ovulation problems, and caffeine under 200 milligrams a day does not seem to affect your ability to conceive. The American Society for Reproductive Medicine adds recreational drugs to the list and notes that time to conceive increases with age.
Weight also plays a role. A research review notes that being significantly overweight or underweight can inhibit normal ovulation. Mayo Clinic says stress is unlikely to keep you from getting pregnant, though managing it supports your overall health. For partners, research links smoking, heavy alcohol use, obesity, and heat exposure with lower sperm quality.
Frequently Asked Questions
Does Shred415 offer classes designed for fertility or fertility treatments?
No. There are no classes built specifically for fertility. The mix of treadmill and strength work can be scaled to your level, and you can find your nearest studio on our locations page.
Can I do Shred415 while trying to conceive naturally?
Many people keep exercising while trying to conceive. Because you choose your pace, you can keep your effort moderate. Check with your provider first, especially if you have irregular cycles or a medical history.
