What Makes Flexis Fitness Different: Our Science-Based Approach
The struggle is real—and it’s biological
If you’ve been eating less, moving more, and still watching your weight, mood, and energy swing, you’re not “failing.” Your body is doing exactly what biology trained it to do: protect you when inputs look stressful or inconsistent. In midlife, shifting estrogen, progesterone, and testosterone change how you store fat, recover, and regulate appetite. That’s why a one-size-fits-all plan that worked at 28 often stalls at 42.
Aha! moment: You don’t have a willpower problem—you have a signaling problem. When we change the signals, your body starts cooperating again.
I’m Alexis Giurleo, a biologist specializing in cellular & hormonal health. I work alongside a trusted team of physicians to translate complex science into simple, repeatable steps that fit real life. This article is your inside look at how our science-based method helps women 35+ get steady results—without extremes.

Our philosophy in one sentence
Work with your biology, not against it.
Translation: we support the cells that run your metabolism, we train for midlife hormones, and we reduce stress signals so your body stops defending and starts responding.
Pillar 1: Cellular health drives hormone health
Hormones don’t act in thin air—they’re made and metabolized inside cells. Your mitochondria (the cell’s “power plants”) turn fuel into energy and host the first step of steroid hormone synthesis (the conversion of cholesterol to pregnenolone). When cellular energy is low or inflamed, hormone output and sensitivity suffer; mood, sleep, and fat-burning follow. (PubMed)
Aha! moment: If the cell’s engine is under-fueled, your hormones can’t “out-perform” the problem.
What we do, practically:
-
Build protein-forward meals (25–35 g at breakfast) and pair carbs with fiber + fat to reduce blood-sugar swings.
-
Increase fiber (25–30 g/day) to support gut-driven anti-inflammatory pathways.
-
Improve sleep windows (lights down + wind-down routine) because nighttime is when mitochondria do their best repair.
Pillar 2: Hormone-smart training (muscle is a message)
After 35, you don’t “earn fat loss” by doing more HIIT and eating less; you earn it by protecting muscle, because muscle is metabolically active tissue that improves insulin sensitivity, stabilizes blood sugar, and raises your resting burn.
Our approach:
-
Strength 2–3x/week (squat/hinge/push/pull), progressive overload, and 1–2 reps “in reserve” to avoid nervous-system burnout.
-
Zone-2 cardio (easy conversation pace) for mitochondrial density without spiking cortisol.
-
Walks + mobility in the morning; save intensity for later in the day when cortisol is naturally lower.
Aha! moment: Muscle isn’t just “tone”—it’s a hormone helper that makes nutrition work again.
Pillar 3: Stress-aware nutrition beats “eat less”
Aggressive deficits teach your body to defend (lowering resting burn and elevating appetite signals). Research shows appetite/satiety hormones can remain altered for a year after weight loss, which helps explain the frustrating regain cycle. We avoid that trap by fueling first, then phasing any calorie cuts—briefly, strategically, and only after sleep, steps, and strength are consistent. (New England Journal of Medicine)
Aha! moment: If your body thinks you’re under threat, it won’t spend. Safety first, then fat loss.
Your first 7-day reset:
-
Breakfast within 60–90 minutes of waking: 25–35 g protein + fiber + fat.
-
10–15 minute walk after your largest meal to lower glucose spikes.
-
Two strength sessions this week; keep one zone-2 session.
-
Wind-down: 60–90 minutes pre-bed, lights down, hot shower, phone out of the room.
How personalization works here (and why it matters)
Two women can eat the same food, do the same workout, and get different results. That’s because cycles, stress loads, sleep, thyroid, iron status, and life context vary. We personalize with:
Cycle-aware notes (even if cycles are irregular)
You’ll log sleep, energy, cravings, and mood across weeks. Patterns reveal whether estrogen variability or low progesterone is driving symptoms. (Example: 2–3 a.m. wakeups + heavier cycles often point to low progesterone relative to estrogen.)
Targeted labs (when they change the plan)
We don’t test everything; we test what matters for you—e.g., thyroid panel, fasting insulin, ferritin/iron, vitamin D, and cycle-timed hormones as indicated—then we interpret results next to symptoms so the plan fits your stage, not a lab number floating in space.
Precision nutrition + training blocks
-
Some clients can progress on 2 strength days; others need 3.
-
Some thrive on higher-carb training days; others need evening carb curfews to sleep.
-
We use 2–4 week blocks so your body has time to adapt without burnout.
Aha! moment: Your plan should look like you—not a template.
Why “eat less, move more” failed you (and how we fix it)
When intake drops too low and intensity stacks too high, your brain reads threat. The result is metabolic adaptation: lowered resting burn, elevated hunger hormones (e.g., ghrelin), reduced satiety (e.g., leptin), and a body that clings to energy—especially at the midsection. We reverse this by building safety signals first (steady meals, sleep, strength), then introducing brief, well-timed calorie deficits once the foundation holds. (New England Journal of Medicine)
Aha! moment: The goal isn’t to suffer more—it’s to convince your metabolism it’s safe to let go.
What happens in real life (client snapshots)
“Once Alexis explained the cellular piece, it clicked. We adjusted my training and evening meals, and the 3 a.m. wakeups disappeared. I’m lifting heavier than I did at 35.” — Jenna, 46
Expert FAQ
How do I know if this is “hormonal weight” or just stress?
Often both. In perimenopause, estrogen variability plus lower progesterone amplifies the stress response, so cravings and belly fat increase even with “clean eating.” We track patterns for 6–8 weeks, then tailor labs and training accordingly.
Do I need to cut carbs to lose fat?
No. We use carbs strategically (often around training) and always paired with protein/fiber/fat. Carbs help with recovery and mood; the key is timing and dose.
Should I get hormone labs right away?
Sometimes—but labs in perimenopause can swing. We combine cycle-aware notes with targeted tests (thyroid, fasting insulin, ferritin/iron, vitamin D; cycle-timed hormones when useful) and adjust based on how you actually feel.
Will lifting make me bulky?
No. Muscle improves insulin sensitivity, steadies blood sugar, protects bone, and gives you shape. It’s a cornerstone of midlife metabolism.
Can I start if I’m exhausted and short on time?
Yes. We begin with two 30-minute strength sessions, protein-first breakfast, a 10-minute walk after dinner, and a wind-down. Momentum (and energy) follows.
Why you haven’t heard this before
Most programs are built on short-term scale changes and research on younger men. They miss how female hormones + cellular energy + stress change the rules in your 40s. When you try harder on the wrong strategy, your body digs in.
Aha! moment: Your plan didn’t fail—you were using a plan not designed for your biology.
Why I do this work
I’m Alexis. A cycling accident once derailed my own hormones and energy. That season taught me how fragile—and how fixable—our signaling is. Today, I translate the science for women who are tired of guessing, and I partner with our physician team to make care personal, evidence-based, and humane.
Why Flexis Fitness works
We combine cellular science with compassionate coaching and clinician guidance when medications or hormone therapy are appropriate. No fads. No shame. Just a system that finally makes sense—and lasts.
