Calculate Your NeedsDial in Nutrition
You can't out-train a bad diet. Whether you want to lose fat or build muscle, it starts with knowing your numbers.
Train Smarter
Intensity matters. Make sure you're training in the right heart rate zones to achieve your specific goals, from fat burning to VO2 max improvement.
Heart Rate Zones
Calculate your 5 training zones based on your resting heart rate (Karvonen formula).
Master Recovery
Growth happens when you rest, not when you train. Syncing your sleep with your natural circadian rhythm (90-minute ultadian cycles) ensures you wake up energized.

Frequently Asked Questions
How do I calculate my macros?
First, determine your TDEE (Total Daily Energy Expenditure). Then, split your calories based on your goal. A common split for muscle gain is 40% Protein, 30% Fat, 30% Carbs.
What is a good heart rate zone for fat loss?
Zone 2 (60-70% of Max Heart Rate) is often cited as the 'Fat Burning Zone' because the body primarily uses fat for fuel at this intensity.
How much sleep do I really need?
Most adults need 7-9 hours of sleep. However, quality matters more than quantity. Aim for 5-6 full 90-minute sleep cycles.
Is BMI accurate?
BMI is a useful screening tool for the general population but can be inaccurate for athletes with high muscle mass, as it doesn't distinguish between muscle and fat.
