Train for muscle. Every number has a reason.

Workout Wizard is an iPhone and Apple Watch app for hypertrophy training. It plans your weights and sets, and adjusts next week from how this one felt. Built by a sports scientist.

An example set: bench press, week 2 of 5

62.5kg: The weight, worked out from what you lifted last week.
×10: The reps to aim for in this set.
2RIR: Stop 2 reps short of failure: week 2’s effort. Closer each week, then a deload.

How it plans your training

A plan that listens

After each workout you rate soreness, pump and workload. Your answers set next week’s sets and weights, muscle by muscle.

A few taps after each exercise
Sets go up, hold or come down for each muscle
Weights and reps follow what you lifted

Weeks that build, then a deload

Train in blocks of a few weeks. Each week asks for a little more effort, counted in reps in reserve, and a lighter week lets you recover before the next block.

An effort target for every week
The deload week is built in

Watch every lift move

Each exercise keeps its sessions, its best estimated one-rep max and a chart of where it’s heading.

Estimated one-rep max for every session
Every set you’ve logged, by date
Deload weeks kept out of the trend

What it does in the gym

What lifting really costs: Estimates the energy of every set from the load, your reps and your body, and refines it with your heart rate between sets.
Smart Rests: Starts a rest timer after each set, from the research on rest and muscle growth, and tunes it to how your rests feel.
On your wrist: Apple Watch keeps your heart rate and the rest timer while you train.
On your Lock Screen: A Live Activity keeps the current set on the Lock Screen.
Saved to Apple Health: Your workouts save to Apple Health, next to the rest of your training.
Private by design: Your training lives on your iPhone. There’s no account to create.
