Can You Work Out Too Much While Trying to Conceive?

Exercise is an essential part of a healthy lifestyle, but when you’re trying to conceive (TTC), more is not always better. While moderate movement supports hormone balance and overall well-being, excessive or intense exercise can actually negatively impact fertility.

If you’ve been struggling to get pregnant and work out frequently, it may be time to assess whether your fitness routine is helping or hurting your fertility.

How Excessive Exercise Affects Fertility

1. Hormonal Imbalances & Irregular Cycles

Your menstrual cycle is a key indicator of fertility health, but over-exercising can disrupt it. Intense physical activity can lower levels of key reproductive hormones like estrogen and progesterone, leading to:

• Irregular ovulation

• Missed or unpredictable periods

• Difficulty conceiving due to hormone imbalances

If your cycle has become irregular or absent, your body may be signaling that it’s under too much physical stress.

2. Energy Deficits & Fertility

Your body requires a delicate balance of energy to support reproductive functions. If you’re burning more calories than you’re consuming, your body may prioritize survival over reproduction, leading to:

• Decreased hormone production

• Poor egg quality

• Irregular ovulation or anovulation (lack of ovulation)

If you’re working out intensely without fueling your body properly, your fertility may suffer.

3. The Stress Response & Cortisol Overload

Excessive exercise especially high-intensity workouts can increase cortisol levels, your body's primary stress hormone. Elevated cortisol can interfere with:

• Ovulation and menstrual cycle regularity

• Progesterone production (needed to sustain pregnancy)

• Thyroid function, which plays a role in metabolism and fertility

If you’re pushing yourself to exhaustion in the gym, your body may interpret it as stress, making conception more difficult.

4. The Role of Body Fat in Fertility

While maintaining a healthy weight is important for fertility, having too little body fat can be just as problematic as having too much.

Low body fat levels often seen in athletes or those doing excessive cardio can lead to:

• Hormonal imbalances

• Irregular or absent periods (hypothalamic amenorrhea)

• Difficulty sustaining a pregnancy due to low progesterone

If you’re experiencing cycle disruptions and have very low body fat, it may be time to ease up on intense workouts and focus on hormone nourishing movement instead.

Finding the Right Balance

Exercise should support your fertility not work against it. Here’s how to find a fertility friendly workout routine:

• Prioritize Gentle, Hormone-Supporting Workouts – Walking, yoga, Pilates, and strength training in moderation can support blood flow and hormone health.
• Fuel Your Body Properly – Ensure you’re eating enough protein, healthy fats, and complex carbs to support hormone balance and ovulation.
• Listen to Your Body – If you’re feeling fatigued, experiencing irregular cycles, or struggling with infertility, it may be time to adjust your routine.
• Reduce Stress – Incorporate breathwork, rest days, and relaxation techniques to lower cortisol and support conception.
