Coach Aditya Has All of Your Results.

Coach Aditya's Bloodwork Interpreter analyses 48 markers with performance-specific thresholds — because a ferritin of 35 or testosterone of 350 is technically normal but functionally limiting for training.

What 'normal' means is not the same as 'optimal.' Your bloodwork is read in the context of your performance, your recovery, and your training — not just disease absence.

What blood tests should I get for fitness and performance?

A practical minimum panel includes CBC, ferritin, vitamin D 25-OH, thyroid panel (TSH, Free T3, Free T4), fasting insulin, fasting glucose, HbA1c, lipid panel, and total testosterone for men. Coach Aditya's recommendation: pair this with symptom tracking and the Hormonal Health Optimizer so markers are read in context, not as isolated lines on a report.

Why normal blood test results can still limit your training

Clinical ranges are built to flag disease risk, not peak performance. A ferritin near 35 ng/mL may pass the lab interval but still reduce endurance and recovery quality. Coach Aditya's Bloodwork Interpreter uses performance-oriented interpretation across 48 markers so you see where function sits relative to training goals.

How often should athletes get bloodwork done?

During high-volume or fat-loss phases, every 3-6 months gives feedback before symptoms become severe. Annual testing is the minimum baseline for recreational lifters. Coach Aditya's recommendation: retest earlier after prolonged deficits or performance drops, then align supplements with the Supplement Stack Builder and nutrition with the Clinical Diet tool.

What ferritin level is too low if you lift weights five days a week?

Coach Aditya's recommendation: treat ferritin below 30 ng/mL as a recovery bottleneck even when haemoglobin looks acceptable. Between 30 and 50 ng/mL, many lifters still report flat endurance and slower strength progress. Re-check ferritin 8-12 weeks after correcting intake, and keep calorie targets honest with the Calorie Planner so hard training is not stacked on top of hidden iron debt.

Frequently Asked Questions

Start with CBC, ferritin, vitamin D 25-OH, thyroid panel, fasting glucose, fasting insulin, HbA1c, lipid panel, and sex-hormone markers where relevant. This panel covers oxygen transport, endocrine function, inflammation, and glucose control. Coach Aditya recommends adding context markers
For many men, performance outcomes are often better around the 500-800 ng/dL range rather than simply staying above a low clinical cutoff. Context matters: sleep debt, stress load, and calorie deficits can suppress output even when total testosterone appears acceptable. Always interpret with free testosterone and symptom pattern.
Ferritin reflects iron stores. Levels below about 30 ng/mL are commonly linked to lower work capacity, poorer oxygen delivery, and reduced endurance quality. Athletes often feel this as unexplained fatigue and slower recovery. Coach Aditya recommends correcting intake and absorption factors before forcing harder training.
TSH alone is not enough for training-focused interpretation. Free T3 is the active hormone influencing metabolic output, while Free T4 shows production reserve. A practical performance lens often watches TSH around 1-2.5 with symptom context, not only broad disease-reference ranges.
HOMA-IR is calculated as fasting insulin multiplied by fasting glucose, divided by 405. Values above roughly 2.5 can indicate reduced insulin sensitivity, which can slow fat-loss response and worsen energy swings. Coach Aditya uses this marker to guide carbohydrate structure and activity targets.
A practical target range is often around 50-80 nmol/L for training support, with retesting after supplementation. Values below this range can correlate with lower recovery quality and reduced performance consistency. Vitamin D should be interpreted with lifestyle, sun exposure, and dietary fat intake.
High-sensitivity CRP above 3 mg/L can indicate systemic inflammation that may be affecting recovery and training readiness. This does not diagnose a single cause, but it signals load-management and health review are needed. Coach Aditya pairs CRP with sleep, nutrition, and stress trend data.
For active lifters, every 3-6 months during intense phases is ideal. At minimum, test annually even when training is stable. Retest sooner after long dieting blocks, repeated illness, or persistent plateaus to catch physiological bottlenecks before they compound.
