How RecalFit Works
A clear look at how our algorithms calculate your calories, build your workout splits, and protect your joints while you train.
Daily Calorie & Macro Calculations
Your body burns calories constantly, even at rest. RecalFit calculates your baseline energy needs using the gold-standard Mifflin-St Jeor formula, then adjusts daily based on your real activity from Apple Health:
Deficits are capped at safe weekly rates so you keep muscle and protect your energy.
Targets 1.8g to 2.0g per kg of bodyweight to speed up recovery between sessions.
Minimum safe floors (1,500 kcal male / 1,200 kcal female) prevent crash dieting.
Smart Workout Splits & Progression
Choose how many days you want to lift each week. RecalFit organizes your sessions into balanced splits that hit every muscle group with the right recovery intervals:
Great for 3 to 6 days a week. Separates chest & shoulders (Push), back & biceps (Pull), and legs for focused stimulus and recovery.
Ideal for 4 days a week. Hits your entire upper and lower body twice per week with optimal recovery days in between.
Built for busy lifestyles (2 to 3 days a week). Uses big compound movements so you build strength and muscle without living in the gym.
Joint Protection & Exercise Swaps
Pain kills consistency. If an exercise hurts your shoulders, knees, or lower back, RecalFit immediately provides an alternative exercise that works the exact same target muscles without the joint strain.
