Strength Training for Hormonal Health: Why Women Need to Lift Weights

I’ll never forget the season of my life when I lost my period for almost a full year. At the time, I was training for a marathon, pushing my body to extremes with HIIT workouts, and under-eating without even realizing it. On the outside, I looked “fit,” but inside, my hormones were completely out of balance. As a mom of two boys, business owner, and on the go, I wanted to be healthy and energized, not run down, depleted, and hormonally burnt out.

The turning point came when I started finding a balance, lifting more weights and incorporating the barbell. I started strength training with progressive overload (simply lifting a little heavier or smarter each week), focused on eating enough to fuel my body, and my period came back. Not only that, but I started to see real changes in my strength, body composition, energy, and confidence.

That’s when I learned: strength training isn’t just about toned muscles, it’s about hormonal health.

Why Hormones Matter for Women

Hormones regulate everything. Your energy, metabolism, sleep, stress, mood, and even fat storage. When they’re off, you feel it. Irregular or missing cycles, fatigue, cravings, stubborn weight, and mood swings are all signs something deeper is going on.

But here’s the good news: lifting weights is one of the best things women can do to restore balance.

How Strength Training Supports Hormonal Health

1. Balances Estrogen and Progesterone

Heavy cardio can stress the body and throw off your cycle. Strength training, on the other hand, helps regulate estrogen and progesterone, making periods more regular and PMS more manageable.

2. Boosts Testosterone Naturally

Yes, women need testosterone too, for energy, muscle tone, libido, and drive. Lifting weights boosts testosterone in a healthy, natural way. You won’t get “bulky” and you’ll feel stronger and more sustained energy. 

3. Helps Lower Cortisol (Stress Hormone)

When I was just doing HIIT workouts, my cortisol was through the roof. That stress hormone can wreak havoc on sleep, mood, and fat storage. Lifting, paired with rest days, helps regulate cortisol and improves your body’s ability to handle stress.

4. Improves Insulin Sensitivity

Muscle acts like a sponge for blood sugar. The more lean muscle you build, the better your body can handle carbs, cravings, and energy dips throughout the day.

5. Supports Thyroid & Metabolism

If you’ve ever felt like your metabolism “slowed down,” this one’s for you. Muscle mass keeps your metabolism humming even at rest, making it easier to maintain or lose weight without extreme restriction.

Don’t Be Afraid to Eat More

One of the biggest shifts for me was realizing I needed to fuel my body. Restricting calories was part of what led to my hormones shutting down in the first place. Once I ate enough protein, carbs, and fats to support my training, everything changed…my energy, my period, my mood, and my progress.

When to Get Bloodwork Done

If you suspect your hormones are off, don’t just guess—get bloodwork done. I personally use Joi & Blokes (will link below), who specialize in hormone health for women and men. Knowing exactly where your estrogen, progesterone, testosterone, thyroid, and cortisol levels stand gives you clarity—and a roadmap for how to fix it.

Getting Started with Strength Training

If you’re new to lifting, here’s how I recommend starting:

• 3-4 sessions per week starting out
• Focus on compound movements like squats, deadlifts, presses, and rows
• Use progressive overload: lift a little heavier, add a rep, or slow down your tempo each week
• Prioritize rest days your hormones thrive when you recover, not when you burn out

If you are wondering what programs to start with, my app, EMPWR by Sam, has so many! 

The Bottom Line

Strength training gave me back more than my period…it gave me my health, energy, and confidence. For women, it’s not just about looking fit; it’s about supporting your body at a hormonal level so you can thrive in every season of life.

So if you’ve been stuck in the cardio-only cycle, let this be your nudge: pick up the barbell, eat to fuel your body, and if you’re unsure where your hormones stand, get the bloodwork. You deserve to feel strong, balanced, and unstoppable.
