## What is IRONSPLIT 4?

IronSplit is a no-nonsense workout tracker built around the proven 4-day upper/lower training split — the most effective program structure for intermediate and advanced lifters.

STRUCTURED 12-WEEK PROGRAMS
Select your week (1–12) and let IronSplit guide your progression. Each workout is structured around the compound and isolation movements that drive real strength and size gains.

TRACK EVERY SET
Log your weights and reps for every exercise across all 4 training days. Your data is saved automatically and available offline — no account required.

PREVIOUS WEEK COMPARISON
See exactly what you lifted last week on every exercise, so you always know when to add weight and how much.

REST TIMERS WITH SOUND
Built-in rest timers for compound (1:30 – 4:00) and isolation (30s – 1:30) movements. An audible beep and vibration alert you when it's time to lift again — no need to watch the screen.

EXERCISE VARIATIONS
Swap any exercise for an alternative variation that targets the same muscle group. Your swap preference is saved, so your personalised program stays consistent week to week.

KG / LBS TOGGLE
Switch between kilograms and pounds at any time. Your preference is saved across sessions.

DARK & LIGHT MODE
Follows your system appearance or set it manually — designed to look sharp in the gym lighting.

CLEAN AND FAST
No sign-up, no subscription, no fluff. IronSplit loads instantly and stays out of your way so you can focus on training.

THE 4-DAY UPPER/LOWER SPLIT
Day A – Upper (Push focus)
Day B – Lower (Squat focus)
Day C – Upper (Pull focus)
Day D – Lower (Hinge focus)

All data is stored locally on your device using secure on-device storage. IronSplit does not require an internet connection to function.
