Every rep you perform sends a real and powerful signal to your bones, and whether you feel it immediately or not, your future self responds to the way you train right now.

This is why I worked with to build the Power Happens Collection for women wh...

When sprint intervals start feeling easy, the answer is simple. Go harder. Push the intensity. Your body has adapted and it's ready for more. Stop coasting and start chasing! 30 seconds, when done correctly and with proper intensity is a LONG TIME!!

I think this is one of the most important messages to understand when it comes to how we strength train — especially as we get older.

It's about building and maintaining enough muscle to support not just function, but our long-term health.

I get asked all the time for recipe ideas and while I am not a nutritionist, I will share a few of my favorite things here and there, including these date bites.

These no-bake chocolate date bites are perfect for energy and recovery (and delicious!)...

Women live longer than men.

On paper, we "win" longevity. But here's the uncomfortable truth: many women are living longer, but those years are impacted by cognitive decline, cardiovascular disease, frailty, and loss of independence, especially afte...

Here's the truth most women are never told:

Your body isn't broken, it just needs a different way of working out and eating in menopause.

If you're going through perimenopause or menopause, and walking into the gym leaves you feeling confused, disc...

I didn't start doing this work to change the world. I started because I kept being told I couldn't—because I was a girl, because I was a woman with a PhD who thought too much.

That defiance became a career. And that career kept running into the same...

We spend a lot of time talking about muscle, metabolism, and performance, but not nearly enough time talking about the brain. Yet women are disproportionately affected by cognitive decline and Alzheimer's disease. Alzheimer's is a brain condition tha...

Why do we rest for 2 minutes?

Resting 2 minutes between sets isn't lazy — it's strategic. 🧠
It gives your muscles time to replenish ATP (energy), so you can lift heavy again with good form and actually build strength.

Short rest = more fatigue = le...

This isn't about "toning."

It's about survival.

As women age, losing strength and power is directly linked to increased mortality.

Read that again.

Strength protects independence.
Power protects your brain.

Heavy lifting stimulates neuroplastici...

A question we get all the time. Does going on HRT or MHT mean you need more protein or a different recovery approach? Dr Stacy Sims says no. The basics don't change. Nail those first!

[Dr. Stacy T. Sims @drstacysims554]

For the last 25 years, I've been working to optimize women's health and performance using a research base that was never designed for women in the first place.

That gap has real consequences. Less than 6% of sports science research focuses solely on...

Not all protein powders are created equal. Here are my go-to picks and what I actually look for on the label. Ingredients matter more than the marketing. Here's what to look for. 👆 Personally we both use @ products!

Rest days. Are you doing them right? Loretta sits down with Dr Stacy Sims to find out. Watch to see if yours are structured the way they should be!

For peri- and postmenopausal women, declining estrogen makes resistance training even more important for maintaining muscle quality, strength, and bone density. Heavy and explosive loading—appropriately progressed and well-fueled—remains one of the m...

I love coffee. I'm addicted to espresso and had to find a way to integrate it into my morning fuel routine.... hence, Protein Coffee.

How do you fuel in the morning, and are you someone who is naturally hungry in the morning, or do you have to fake ...

For a long time—going back to my postdoc days—I've experienced firsthand how far women's health and fitness research lags behind the male-focused default data. It's become my life's mission to help fix this, so today I'm extremely proud to announce a...
