Why FytlY Works — Personal, Habit-powered, Evidence-based
Our AI builds your workout plan from your goals, health data, and any injuries or pain patterns you want to fix. Rest days swap between cardio or mobility/stretching. We help you track four high-impact habits: 2 g/kg protein, ≥ 2 L water/day, ≥ 7,000 steps/day, and avoiding sugary foods.
Health impact you can expect
- Lower all-cause mortality — Meeting guideline activity levels reduces premature death; combining aerobic + strength training is strongest.
- Cardiometabolic protection — Higher activity lowers risk of heart disease, stroke, type 2 diabetes, and common cancers.
- Stronger bones; fewer falls — Resistance training maintains bone mineral density in older adults.
- Back pain resilience — Exercise therapy improves pain and function in chronic low back pain.
- Brain & mood — Physical activity lowers dementia risk; exercise effectively treats depression.
The four default habits
- ≥ 7,000 steps/day — 50–70% lower mortality in middle-aged adults.
- 2 g/kg protein — Maximizes muscle gains with resistance training.
- ≥ 2 L water/day — Reduces kidney stone recurrence.
- Avoid sugary foods — Each daily sugary drink cut reduces T2D risk by ~18%.
Estimated life expectancy gains
- Start before 30: +4–8 years
- Start 30–49: +3–7 years
- Start 50+: +2–6 years
