About

Ferrum

Strength training built around your cycle. Because the best athletes don't ignore their biology — they train with it. —— TRAIN WITH YOUR CYCLE, NOT DESPITE IT Your hormones are the most underused performance tool in women's fitness. Ferrum tracks your Menstrual, Follicular, Ovulatory, and Luteal phases and uses them to drive every recommendation — from load adjustments to rest guidance to when to attempt a PR. —— GUIDED WORKOUTS THAT ACTUALLY ADAPT Follow a step-by-step guided session or log freely in manual mode. Navigate exercises like a playlist — skip ahead, go back, track each set individually with different weights and reps. Your workout saves as you go, so nothing is ever lost. —— KNOW WHEN TO PUSH. KNOW WHEN TO RECOVER. Ferrum's progressive overload engine monitors your performance history and your cycle to flag peak strength windows automatically. When your body is primed for a personal best, Ferrum tells you. When it needs recovery, Ferrum tells you that too. —— BUILT FOR WOMEN WHO LIFT Not a wellness app. Not a step counter. Ferrum is a serious training tool — weekly splits, PR tracking, progress photos tied to your cycle phase, and coaching that understands your biology. Your body has a rhythm. Train like it.
