Built each day from your recovery, your lifts and your own routine - and explained by a coach who remembers how last week felt. First month free.
Most apps give you a program. FitBoi gives you a coach who remembers - which muscles you trained yesterday, what you lifted last month, that Thursday is your pull day, and that last week felt hard. Every session is built from that, then explained.
IT KNOWS YOUR BODY TODAY
• Recovery tracked across 18 muscles - heavy legs on Sunday means legs sit out Tuesday
• Follows the routine you actually do, not a template: your chest day stays your chest day
• Never sends you back to yesterday's muscles until they've had their week
• Your equipment, your time window, your call: auto, push/pull/legs, or hand-pick muscles
IT KNOWS HOW LAST TIME WENT
• Reps climb first, then loads - the way good coaches run it
• Rate the effort and the next session adjusts; plateaus reset, hard weeks deload
• Back after a break? It eases you in instead of chasing an old best
• Weekly meters per muscle group, so nothing gets quietly forgotten
IT EXPLAINS ITSELF
• A brief before every workout: why this, why these numbers
• One useful cue per exercise, from a coach who's read your log
• A debrief after: what moved, what changes next time, every record called out
MORE THAN LIFTING
• Cardio on the machines you own - as a warm-up, a finisher, or a whole day
• Yoga and pilates flows when you need to move, not lift
• Save any session as a routine and plan it for the days you want
THE REST, DONE PROPERLY
• Photo previews, setup, cues and common mistakes for every exercise
• Rest timer on your lock screen, with a chime
• Progress, records, consistency, bodyweight; workouts saved to Apple Health
• Import from Fitbod, Strong or Hevy - it knows your go-to lifts on day one
• Private by design: your data lives in your own iCloud, no account
Try everything free for a month. Then FitBoi is an auto-renewing subscription (monthly or yearly) - cancel any time in Settings.

• Workouts saved to Apple Health
• Faster exercise library and smoother Today screen
• Fixes for coach tips on per-dumbbell and bodyweight exercises, exercise chips wrapping, and a sturdier trainer brief
