You exercise regularly, eat clean (most days), and your doctor says your basic blood work looks “normal.” So why do you still feel run down, struggle with recovery, or plateau in your training?

The truth is: normal doesn’t mean optimal.

At Signature Strength, we go beyond traditional lab work to uncover what’s really going on beneath the surface. Because if you’re serious about performance, longevity, and energy—you can’t afford to guess.

The Limits of Traditional Blood Testing

Your typical annual blood panel looks at:

Complete blood count (CBC)
Basic cholesterol breakdown
Blood glucose
Maybe a thyroid marker if you ask

While helpful for catching major medical red flags, these panels miss the nuanced markers that influence your energy, metabolism, hormones, and recovery.

What Fitness-Focused Panels Can Reveal

Advanced blood testing through Signature Strength’s referral partners (like Marek Health) uncovers data that helps us customize your fitness and lifestyle program in ways that most coaches simply can’t.

Here’s what we look at:

🔬 Hormone Health

Testosterone (total & free)
Cortisol and stress response
Thyroid function (TSH, T3, T4, reverse T3)→ Why it matters: Hormonal imbalances can sabotage your gains, recovery, and mood.

🔬 Inflammation Markers

C-reactive protein (CRP)
Homocysteine→ Why it matters: Chronic low-grade inflammation hinders muscle growth, energy, and joint health.

🔬 Metabolic Insight

Fasting insulin
A1C
Vitamin D→ Why it matters: Insulin resistance often shows up years before it becomes a diagnosis—and it can impact how your body builds and stores fat.

How We Use the Data

Unlike a doctor’s office that just flags what’s “out of range,” Signature Strength partners with trusted labs to turn your results into actionable strategies, like:

Adjusting training volume for cortisol patterns
Tailoring macronutrient intake to blood glucose control
Recommending supplements or recovery protocols based on deficiencies
Building a strength + lifestyle plan that works with—not against—your biology

You’ll gain a better understanding of how your body is performing, not just how it looks.

Why This Matters—Especially in Your 30s and 40s

Preventative health is no longer just a buzzword. It’s your competitive advantage.If you want to stay strong, focused, and energized as you age, your blood holds the blueprint.

At Signature Strength, we don’t treat you like an average client—because you’re not. You’re building a high-performing life. And we’ll help you measure and optimize every pillar of it.
