Knows when you're ready

The workout tracker that tells you when to add weight

The progression coach
Stop guessing. Progress on schedule.
Most apps stop at logging. Alzo reads your log and turns it into decisions:
Steps that match your gear
Barbell +2.5 kg, isolation +1.25 kg, dumbbells by the increments you actually own. No impossible jumps.
Backs off before you burn out
Stalled three times? Alzo schedules a deload and ramps you back up — plateaus are part of the plan, not the end of it.
Shows the road ahead
Every exercise card shows how far you are from the next weight bump. Walk into the gym knowing what today is for.
Three steps, zero spreadsheets
-
1
Answer a two-minute quiz
Experience, equipment, goal, schedule — Alzo builds your split, picks exercises and sets safe starting weights.

2
Train
Weights come pre-filled from last time. Rest timers start themselves and match your goal. The next set is always one glance away.

Get stronger
When the log says you're ready, Alzo bumps the weight. When it says you're not, it protects you from yourself.
Everything a lifter needs. Nothing a lifter doesn't.
A plan built for your gear
Full body, upper/lower or push-pull-legs — chosen from what you can actually train with, be it a full gym or two dumbbells at home.
Rests that fit the goal
Strength needs long rests, growth needs shorter ones. Alzo times them automatically and shows the countdown on your lock screen.
206 exercises with video form guides
Every movement has a looping video, step-by-step technique and the most common mistakes to avoid.
Plate calculator
87.5 kg on the bar? Alzo shows exactly which plates to load per side. Brain saved for lifting.
PRs and streaks
Personal records get caught the second they happen. Training streaks keep the habit honest.
Warm-up that ramps you up
Working sets deserve a runway. Alzo generates ramp-up sets from the bar to your top weight.
Health app, both ways
Workouts and calories land in Apple Health. Heart rate flows back live during your session.

Fair questions
Do I need an account?
No. Alzo works the moment you open it. There is nothing to sign up for.
Does it work offline?
Yes. Basement gyms with no signal are exactly where Alzo feels at home. iCloud sync catches up when you're back online.
Do I need an Apple Watch?
No. iPhone alone does everything. The Watch app is there when you want your phone to stay in the bag.
I already train with my own plan. Can I keep it?
Yes. Build your plan exercise by exercise, or let the wizard draft one and edit it freely. The coach works either way.
Which languages does Alzo speak?
English, Polish, Spanish, German, French, Italian and Portuguese.
