She Beat Depression Without Meds by Lifting Weights. Her Doctor’s Unexpected Prescription Changed Everything (And Science Backs It Up)

Mental health struggles can feel overwhelming, especially when the first solution offered is medication.

But what if there was another path—one that could deliver even better results than traditional treatments?

World-renowned fitness expert Senada Greca discovered that path through strength training, and the transformation changed everything.

In a recent conversation on the On Purpose podcast, Greca opened up about her journey from depression and anxiety to becoming one of the most sought-after trainers in the world, working with celebrities like Kim Kardashian and Miranda Kerr.

When Exercise Becomes Medicine

Greca’s story starts in a place many can relate to: the doctor’s office, facing a prescription pad.

I started dealing with depression and anxiety at the same time and working with Physicians you know they’re a little bit quick to push medication on you.

Everything shifted when she found a physician who was also a marathon runner. This doctor suggested something different: getting stronger.

When I saw what kind of a difference working out did for my mental health is when everything changed.

The science backs this up in stunning fashion. Research shows that just 150 minutes of physical activity per week can relieve symptoms of depression and anxiety by 40-60%.

Compare that to psychotherapy and pharmaceuticals, which typically provide 20-30% symptom relief. That’s double the effectiveness from movement alone.

The Five-Minute Solution That Actually Works

When starting a fitness routine feels impossible, Greca has a radical suggestion: start with five minutes.

Most people dismiss this as pointless. But here’s what they’re missing.

Five minutes is just creating that habit. You won’t see drastic results, you might see no results from five minutes, but five minutes today for a week, 10 minutes the next week for a week, and then you start building from there.

The goal isn’t immediate transformation. It’s building consistency.

Research suggests it takes approximately 21 days to establish a foundation, but 66 days to truly solidify a fitness habit.

What to Do in Those Five Minutes

If you’re at home without equipment, Greca recommends using your body weight:

• Squats to a chair: Stand up, sit down, repeat
• Hip thrusts: Shoulders on the couch, feet planted, lift hips
• Add resistance: Hold a kid, a backpack, or any household object

At the gym, warm up for a minute, then cycle through major movements like squats, deadlifts, and rows.

The key? Target the biggest muscle groups for maximum impact.

Why Strength Training Trumps Everything Else

Greca incorporates various exercise modalities, including high-intensity interval training and cardio. But strength training remains her foundation.

The reason is rooted in biology and longevity.

Strength training is proven to increase bone density and muscle mass, which are so crucial to longevity and a healthy longevity.

The Shocking Statistics About Aging

Most people don’t realize how rapidly our bodies deteriorate without intervention.

Bone density peaks at age 25-30, then begins declining. By age 40, we lose bone density faster than we can build it.

Muscle mass follows a similar trajectory. After 30, we lose 3-8% of muscle mass every decade. This accelerates significantly after 50, then speeds up even more at 60.

The consequences are deadly. Approximately 32,000 deaths per year result from fall injuries in adults 65 and older—a number that nearly doubled between 2012 and 2021.

Women face particular vulnerability. They’re more prone to osteoporosis than men, with bone density loss accelerating dramatically during menopause.

Interestingly, while men experience osteoporosis less frequently, their death rate from falls is higher than women’s.

The Motivation Myth Holding You Back

When Greca trains clients, one obstacle appears more than any other: waiting for motivation.

A lot of people rely on motivation. I don’t feel motivated, so how do you get motivated to work out? A lot of the time I just am not motivated. I don’t want to necessarily work out.

Her solution? Stop relying on feelings entirely.

You take those feelings, you put them aside, and you put your shoes on and you keep going because that’s what you do. It’s like brushing your teeth—there’s no negotiation.

Greca makes working out a non-negotiable, not for aesthetics, but for long-term health and mental wellness.

The “I’m Too Busy” Excuse

The second biggest barrier? Time.

Greca isn’t buying it.

I’m sorry but you can always make time for yourself. You can find that time. A lot of the time there’s been arguments back and forth with people on Instagram—you know, I don’t have time—yet two hours later they’re still responding to that same chain of communication. Well, you had two hours right there.

Her advice: Analyze your day. Find pockets of time currently spent scrolling or watching TV.

Better yet, combine activities. Watch your favorite show while doing a 20-minute workout. The entertainment makes time fly while guaranteeing you complete the session.

Debunking the “Bulky” Myth

One misconception keeps women from strength training more than any other.

Women will get like bulky and big and gigantic—that’s like the biggest thing. I don’t want to get too bulky, I don’t want to get too big.

This fear is biologically unfounded.

Female hormones simply don’t allow for the dramatic muscle growth that testosterone enables in men. While individual hormone levels vary, most women won’t develop massive muscles naturally.

I guarantee you that once you start gaining a little bit of muscle you will be addicted. The feeling of strength and confidence that it gives you—those feelings far outweigh any negative misconceptions.

And if someone does feel they’ve built more muscle than desired? Simply adjust the training volume.

Nutrition Essentials for Strength Builders

Exercise alone won’t deliver results without proper nutrition. Greca’s approach is straightforward.

Prioritize Protein Above Everything

Target 0.8 to just over 1 gram of protein per pound of body weight daily.

For a 120-pound person, that’s approximately 120 grams of protein per day. Since a palm-sized piece of chicken contains roughly 20 grams, hitting this target requires intentional meal planning.

Protein is the building block of our body. Always include protein with every meal and maybe even with your snacks.

Pre and Post-Workout Fuel

Before training: 30-60 minutes prior, eat a combination of protein and carbs, slightly higher in carbs for energy.

After training: Consume at least 20 grams of protein to support recovery and muscle building.

However, Greca emphasizes that total daily nutrition matters more than specific pre- and post-workout meals for most people.

What to Leave Out

Minimize refined sugars and opt for complex carbohydrates instead.

Despite recent controversy, Greca still recommends eating fruit. Focus on vegetables and fruit while fitting them into your overall macronutrient targets.

The Mind-Muscle Connection

One of Greca’s most powerful techniques involves mental focus during training.

Truly thinking about the working muscle—there actually are studies that show that if you are thinking of the muscles that you’re working, that actually creates muscle growth. The muscle gets bigger.

This isn’t pseudoscience. Research demonstrates that visualizing muscle activation during exercise enhances results.

Some studies even showed muscle development in subjects who performed mental weight lifting exercises without physical movement.

Greca’s technique: Slow down movements, focus intensely on the working muscle, and even touch the area to create stronger neural connections.

What Training Kim Kardashian Taught Her

Greca relocated to Los Angeles to train Kardashian, and the experience revealed something crucial about achieving elite fitness.

Her dedication—she shows up, shows up on time, and is ready to go. Never does she complain or back away from something that I put her through. And I put her through a lot.

When preparing for specific events or photo shoots, they dial in the training and nutrition with precision.

But the foundation remains consistent dedication. No excuses, no backing down.

Starting From a Place of Love

Perhaps Greca’s most important lesson transcends specific exercises or nutrition protocols.

I want us to start from a place of love for ourselves, not from ‘I need to lose 20 pounds’ because that again comes from ‘I hate this 20 pounds that’s on me.’

The language we use—both spoken and internal—shapes outcomes dramatically.

Approaching fitness from self-hatred creates resistance. Approaching it from self-love and health creates sustainable transformation.

Greca practices gratitude every night, specifically including appreciation for her body. This shift from criticism to gratitude changed everything.

The Takeaway: Just Start

Whether you’re battling mental health challenges, worried about aging, or simply want to feel stronger, Greca’s message is clear.

Start small. Start now. Start from love.

Five minutes today becomes ten minutes next week. Ten minutes becomes twenty. Before long, you’ve built a habit that could literally save your life.

The research is overwhelming: physical activity rivals or exceeds medication for mental health. Strength training prevents the muscle and bone loss that leads to deadly falls. Movement builds not just physical strength, but confidence and resilience.

You don’t need perfect motivation. You don’t need hours of free time. You don’t need to wait until you “feel ready.”

You just need to begin.
