Health & Fitness — everything you need in one workflow

Before you can set a goal, you need a baseline. BMI gives you a quick health classification; body fat percentage tells you what's actually there; ideal weight shows you where clinical guidelines put a healthy range for your height.

Every goal — lose fat, build muscle, maintain, or perform — starts with knowing your numbers. BMR is the calories your body burns at rest. TDEE is BMR multiplied by your activity level. The calorie calculator converts those into a daily target with safe surplus or deficit ranges.

Calories tell you how much; macros tell you what. Protein preserves muscle during a cut and builds it during a bulk. Carbohydrate fuels training. Fat supports hormones. Water is often the most neglected variable. If you fast during Ramadan or follow a halal diet, these tools work the same — adjust meal timing, not the targets.

Knowing your training zones stops you from going too hard on easy days and not hard enough on hard days. The one-rep max calculator turns a set of 8–10 reps into a strength benchmark without a risky single-rep attempt. The pace calculator converts a target 5K or marathon time into a per-kilometre or per-mile pace you can actually run to.

Progress is rarely linear. The weight loss calculator shows realistic weeks-to-goal projections so you don't abandon a plan that's working. Sleep is where the body adapts to training — the sleep calculator aligns your bedtime with complete 90-minute cycles. Waist-to-hip ratio is the body shape metric NHS cardiovascular risk assessments use.
