How FIT-IN-15 works
From the original FIT-IN-15 studio idea — 10 themed stations, one workout of the day — rebuilt for your living room.
📅 New every day
Your workout is built from today's date, so it's the same all day and brand new tomorrow. Don't love it? Hit ↻ Refresh for a different mix.
🎲 Variety is the point
196 simple, no-setup moves across warm-up, legs, push, hinge, pull, core, balance, animal moves, cardio and cool-down. Thousands of combinations — never the same week twice.
▶ Watch any move
Every exercise has our own written form cues plus a “Watch demo” link that opens video demonstrations on YouTube. We link out — we don't copy anyone's videos, so creators keep their views.
🔀 Swap any station
One move not for you today? Tap “Swap” on that station and FIT-IN-15 deals you a different one from the same family.
Exercise library
Every move in FIT-IN-15. Tap a demo link any time you want to learn one properly.
⚠️ Move smart
FIT-IN-15 is general fitness education, not medical advice. Check with your doctor before starting if you have a medical condition, are recovering from injury, or are pregnant. Use sturdy, stable furniture only, clear your space, and stop any exercise that causes sharp pain. Easier version always beats sloppy version — every station has one.
FIT-IN-15™ — 15 minutes. No equipment. No deciding.
Today's workout is always free right here. Owning FIT-IN-15 ($4.99, once) gets you the complete app as your own downloadable copy: all 196 exercises and the exact-15:00 player, working fully offline on any phone or computer, with any day's workout printable. No subscription, no account — buy once, use forever. Buying also keeps Calder Veritas building.
