Feeling drained halfway through your workouts — even when you’re drinking plenty of water? Here’s the secret: hydration isn’t just about water.

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

In Part 1, we talked about what happens when your red blood cell markers on a CBC come back low — and why that keeps so many women from recovering, building muscle, and looking fit.

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.

You finally start finding your rhythm in the gym, and then it hits you — another cold, another wave of fatigue, another week where your body just won’t bounce back. You’re consistent, you’re disciplined, but you’re still tired, sick, and not seeing the fit look you’re working so hard for.

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
