Blood Work for Lifters: What to Test and How Often

Most lifters over 35 don't know their resting heart rate, their fasting glucose, or their total testosterone. They know their bench press to the pound, but they don't know whether their cardiovascular markers are on track for living another 40 years. That's backward for anyone serious about long-term training.

Annual blood work — the right panel, not just your general doctor's default screening — costs under $200 a year and tells you things no scale or mirror will. Abnormal markers that would kill your training progress if left unchecked show up in blood work years before they show up as symptoms. Catching them early gives you options.

Why annual testing matters

Training masks a lot of metabolic disease. Lifters often look healthy on the outside — good body composition, steady training progress, reasonable energy — while markers are silently drifting in the wrong direction internally. Borderline high blood pressure, creeping insulin resistance, elevated liver enzymes from supplements or alcohol, low testosterone from chronic caloric deficit.

None of these produce symptoms you can feel until they're advanced. All of them show up in standard blood work years earlier.

The panel worth getting

A reasonable annual panel for a training adult male:

Basic metabolic panel

Glucose, sodium, potassium, chloride, BUN, creatinine, calcium. Standard screening that your doctor will order anyway. Shows basic kidney function and electrolyte balance.

Comprehensive metabolic panel (adds liver)

Adds ALT, AST, alkaline phosphatase, albumin, total protein, and bilirubin. Shows liver function — important for lifters using supplements, drinking alcohol, or on any medications.

Complete blood count (CBC)

Red and white blood cell counts, hemoglobin, hematocrit, platelets. Baseline health marker. Shows anemia, infection, or other hematological issues.

Lipid panel

Total cholesterol, HDL, LDL, triglycerides. Your cardiovascular risk profile. Critical to track, particularly as you age.

Hemoglobin A1c

3-month average blood sugar. Better indicator of long-term glucose control than a single fasting glucose. Catches early insulin resistance.

Testosterone panel

Total testosterone, free testosterone, SHBG, LH, FSH. Critical for men over 35. If your total T is in the lower third of normal range (300-450 ng/dL), you're operating below what's optimal for training and recovery.

Thyroid panel

TSH, free T3, free T4. Thyroid affects metabolic rate, recovery, and mood. Subclinical hypothyroidism is common and symptomatic.

Vitamin D

25-OH vitamin D. Widely deficient in adults, especially those not outdoors much. Affects testosterone, recovery, and immune function.

Inflammatory markers

C-reactive protein (CRP) and homocysteine. Chronic inflammation markers. Elevated CRP correlates with cardiovascular risk, recovery problems, and general health decline.

Optional add-ons

Depending on your situation, consider adding:

• Iron panel: ferritin, iron, TIBC. Important if you donate blood, have a vegetarian diet, or have unexplained fatigue.
• Lipid subfractions (NMR LipoProfile): more detailed cholesterol analysis. Useful if your standard lipid panel shows borderline results.
• Cortisol: 8am and 4pm samples. Useful for lifters with suspected chronic stress or HPA axis dysfunction.
• Omega-3 index: measures omega-3 status. Relevant for cardiovascular and inflammatory markers.

What the results should look like

Target ranges for trained adult males (optimal, not just "normal"):

• Total testosterone: 500-900 ng/dL (lab normal often 280-1000 — aim for mid-range minimum)
• Free testosterone: 8-25 pg/mL
• HDL cholesterol: above 50 mg/dL
• LDL cholesterol: below 130 mg/dL
• Triglycerides: below 150 mg/dL (optimal under 100)
• Triglyceride/HDL ratio: under 2.0
• A1c: below 5.6% (optimal 5.0-5.4%)
• Fasting glucose: below 100 mg/dL (optimal 70-95)
• Vitamin D: 40-80 ng/mL (30 is often the lab cutoff — aim higher)
• TSH: 1.0-2.5 mIU/L (wider lab "normal" often 0.45-4.5 — aim for the middle)
• CRP: under 1.0 mg/L (inflammation marker; lower is better)

Results within "normal lab range" but outside the optimal ranges above are worth attention even if your doctor says "you're fine."

Where to get testing

Three options:

1. Through your primary care doctor

Advantages: insurance covers it, your doctor reviews the results.

Disadvantages: many doctors won't order the full panel unless you have symptoms. Testosterone specifically often requires pushing ("I'd like my total T tested as part of my annual exam"). Many doctors still consider anything above 250 ng/dL "normal," missing the optimal range conversation.

2. Direct-order lab services

LabCorp Patient, Quest Direct, Life Extension, OwnYourLabs, and others offer direct-to-consumer lab orders. You pay out of pocket (typically $100-300 for a comprehensive panel), draw at a local LabCorp or Quest location, get results online.

Advantages: full panel without doctor's gatekeeping, results directly to you, lower cost than the list price at hospitals.

Disadvantages: no clinical interpretation provided (you read the results yourself), not covered by insurance.

3. Concierge/private medicine

Private medicine practices, telehealth hormone clinics, longevity clinics. Most expensive option, most comprehensive interpretation.

Advantages: clinical interpretation, follow-up, broader panel.

Disadvantages: cost (often $500-2000+ for annual review).

Reading your results

A few patterns worth understanding:

The "normal but suboptimal" trap

Lab ranges are based on the general population, which isn't a training population. A TSH of 3.5 is "normal" but suggests suboptimal thyroid function. A total T of 350 is "normal" but leaves you training with significantly less hormonal support than you'd have at 650.

Read results against optimal ranges, not just lab-normal ranges. Drift over time within the normal range is meaningful — if your testosterone was 750 three years ago and is 450 now, something changed even if both are "normal."

Lipid interpretation

Total cholesterol alone isn't particularly informative. The relevant markers are:

• HDL (higher is better, above 50 is good)
• Triglycerides (lower is better, under 100 is good)
• The triglyceride/HDL ratio (under 2 is good; over 3 suggests metabolic issues)

A lifter with low HDL and high triglycerides is metabolically compromised even if total cholesterol is normal. A lifter with high HDL and low triglycerides is metabolically healthy even if total cholesterol is borderline elevated.

The testosterone question

If your total testosterone is below 400 ng/dL, something in your lifestyle is probably responsible:

• Chronic sleep restriction (under 7 hours)
• Chronic caloric deficit (cut phases longer than 12 weeks)
• High body fat (above 20%)
• Chronic alcohol use
• Medication side effects (SSRIs, opioids, some blood pressure medications)

Fix these before considering TRT. Most "low T" in lifters under 45 is secondary to lifestyle rather than primary hypogonadism.

Frequency of testing

Annual testing is the default for anyone 35+. More frequent testing is appropriate during specific situations:

• Extended cut phases: test before, halfway through (for 12+ week cuts), and after
• Returning from TRT or cessation of testosterone-affecting medication
• Chronic training fatigue of unclear cause
• Changes in body composition that don't match training inputs
• Before starting any new supplement regimen (baseline)

Tracking one number at one time isn't useful. Tracking the same panel over 3 to 5 years shows trends, which is much more actionable than any single data point.

The action plan

If you haven't had a full panel in the last 12 months:

1. Order a comprehensive panel this month (via doctor, direct-order lab, or concierge)
2. Get the results, compare to optimal ranges (not just lab-normal)
3. Identify any markers outside optimal and address the likely cause (usually sleep, calories, body fat, or stress)
4. Retest in 6 months to verify direction of change
5. Move to annual testing going forward

The cost is a few hundred dollars a year. The benefit is catching metabolic drift years before it becomes a problem. This is infrastructure for long-term lifting, not optional.
