In this episode of the Why Am I So Tired? series, Sarah Whitehead breaks down:

• Why plain water isn’t enough to stop workout fatigue

• The role of sodium, potassium, and magnesium in energy and muscle function 

• How pre-hydrating before exercise can change your endurance

• What to sip during workouts to prevent “crashing”

• Why electrolytes are especially powerful for women with blood sugar issues or autoimmune conditions

The goal isn’t just to push harder in the gym — it’s to build a healthier body. And healthy bodies are energized bodies.

Electrolytes mentioned in today's episode:

• LMNT 
• Trace Minerals 
• Liquid IV
• Pinch of Sea Salt + Lemon

But what if your numbers aren’t low? What if your doctor says your bloodwork looks “normal,” or some values even come back high… and you’re still tired, sore for days, and stuck without results?

In episode 4 of the Why Am I So Tired series, Sarah Whitehead explains why high values on your CBC can be just as big a roadblock as low ones — and how they directly affect your energy, recovery, and ability to look athletic.

You’ll learn:

• Why “normal” lab results don’t always mean your body is optimally healthy.

• How high RBC, HGB, HCT, MCV, MCH, and MCHC can leave you tired, sore, and frustrated.

• The surprising role B vitamins and methylation play in energy, fat loss, and recovery.

• Why you can push through workouts but still fail to adapt and build an athletic look.

In the latest episode from the Why Am I So Tired series, Sarah Whitehead uncovers the overlooked blood marker that could be holding you back: Vitamin D. Low Vitamin D doesn’t just affect your bones — it lowers your immune system, drains your energy, disrupts your hormones, and blocks your ability to build muscle.

You’ll discover:

• Why every workout temporarily dips your immune system — and how low Vitamin D makes it worse

• The connection between Vitamin D, hormones, and the “fit look” you’ve been chasing

• The functional range for Vitamin D vs. what doctors call “normal”

• Symptoms that signal your Vitamin D may be low (and why it matters for fatigue, fat loss, and recovery)

• Simple steps you can take this week to start improving your levels

One of the biggest roadblocks to looking “fit” from your workouts has nothing to do with more cardio, stricter nutrition, or pushing harder in the gym. It’s hidden in your bloodwork.

In this episode from the Why Am I So Tired series, Sarah Whitehead breaks down why low red blood cell markers on your CBC may be stopping you from recovering, building muscle, and finally seeing the fit look you’re working for.

You’ll learn:

• Why red blood cells are the “delivery trucks” that fuel your workouts and recovery.

• What it means when your RBC, HGB, HCT, MCV, MCH, or MCHC come back low.

• Why “normal” lab ranges may not actually be optimal if you want an athletic body.

• The next test you should ask for if your numbers are on the low side.

• What your CBC with differential can reveal about your energy, recovery, and resilience.

• Why this test should be your first step before starting any new fitness or nutrition program.
