I remember when one of our first PCOS clients, Ananya, came to us frustrated. She'd been doing intense HIIT workouts 6 days a week for months but wasn't seeing results. Her symptoms were actually getting worse.
When we looked at her routine together, the problem became clear. But before I explain what changed for her, let's talk about what's actually happening with PCOD/PCOS and why exercise matters so much.
Understanding the PCOD-Exercise Connection
Polycystic Ovary Syndrome (PCOS, also called PCOD) affects roughly 1 in 10 women of reproductive age. It's characterized by hormonal imbalances, insulin resistance, and often, difficulty losing weight.
Exercise matters for PCOS primarily because of insulin resistance.
A 2020 systematic review and meta-analysis by Patten and colleagues in Frontiers in Physiology found that exercise improves insulin sensitivity in women with PCOS even without weight loss. This is significant because it means metabolic benefits occur independent of the scale.
But not all exercise affects PCOS the same way.
What Type of Exercise Works Best?
This is where things get nuanced, and where Ananya's story becomes relevant.
Strength Training: The Underrated Star
A 2017 systematic review by Hakimi and Cameron in Sports Medicine found that resistance training specifically benefits women with PCOS through:
- Improvements in insulin sensitivity
- Better hormonal balance
- More sustainable weight management
- Potential reduction in androgen levels
Why does lifting weights help hormones? Muscle tissue is metabolically active. More muscle means better glucose uptake and improved insulin function.
We typically recommend 3-4 strength sessions per week for our PCOS clients. Nothing extreme. Squats, lunges, rows, presses, deadlifts. The fundamentals.
Moderate Cardio: Yes. Intense Cardio: Maybe Less
Here's where Ananya was going wrong.
Very intense exercise (like HIIT every day) can elevate cortisol, the stress hormone. For some women with PCOS, chronically elevated cortisol may worsen hormonal imbalances.
A 2020 meta-analysis by Patten and colleagues in Frontiers in Physiology, reviewing 33 exercise intervention studies, found that both moderate and vigorous intensity exercise improve PCOS outcomes, with the key being consistent training rather than daily high-intensity sessions.
That doesn't mean HIIT is bad. But doing it 6 days a week might not be helping. For most of our PCOS clients, we limit intense cardio to 1-2 sessions weekly and focus on strength training and moderate movement the rest of the time.
Walking: Seriously Undervalued
I know it sounds boring, but daily walking makes a measurable difference.
Multiple studies on PCOS and physical activity have demonstrated that consistent daily walking improves insulin sensitivity markers, independent of other structured exercise.
Walking doesn't spike cortisol. It's sustainable long-term. And it adds up.
What Changed for Ananya
We cut her HIIT sessions from 6 to 2 per week. Added 3 strength training sessions. Encouraged daily walking.
Within 3 months, her periods became more regular for the first time in years. She lost some weight, but more importantly, her symptoms improved significantly.
Not every client responds the same way, but this pattern repeats often.
Nutrition: You Can't Ignore It
Exercise alone won't manage PCOS. Nutrition plays an equal (maybe bigger) role.
Research consistently points to these principles:
Blood sugar stability matters. Pairing carbohydrates with protein and fat helps prevent blood sugar spikes. This isn't about cutting carbs entirely, but eating them strategically.
Protein intake affects hormone balance. Adequate protein (around 1.2-1.5g per kg of body weight) supports muscle maintenance and helps regulate hunger hormones.
Processed foods make things harder. High sugar, refined carbs, and inflammatory foods tend to worsen PCOS symptoms for many women. Not a moral judgment, just observation from research and client outcomes.
We work with dietitians who specialize in PCOS because the nutrition side matters that much.
The Mental Health Component
One thing that doesn't get discussed enough: PCOS often comes with anxiety and depression.
A 2017 meta-analysis by Cooney and colleagues in Human Reproduction found that women with PCOS have over 4 times higher odds of moderate-to-severe depressive symptoms and over 6 times higher odds of moderate-to-severe anxiety symptoms compared to women without PCOS. Hormonal fluctuations play a role, but so does the frustration of managing a chronic condition.
Exercise helps here too. The mood benefits of regular movement are well-documented, and for our clients, feeling strong and capable makes a real difference beyond the physical metrics.
Where to Start
If you have PCOD/PCOS and feel overwhelmed by conflicting advice, try this:
- 1Walk daily. Aim for 7,000-10,000 steps.
- 2Strength train 2-3 times per week. Start with bodyweight if needed.
- 3Limit intense cardio to 1-2 sessions weekly.
- 4Work with someone who understands PCOS (trainer and/or dietitian).
- 5Be patient. Hormonal changes take months, not weeks.
The condition is manageable. Not easy, but manageable. With the right approach, most women see significant improvements.
And if what you're currently doing isn't working, that's not a personal failure. It might just mean the approach needs adjusting.
