Fitness+ has always worked best in a living room: a trainer on the TV, you on a mat, everyone moving at the same time. That falls apart at a squat rack, where you're waiting for a bench, swapping plates and resting as long as you need between sets. Gym Strength, which Apple announced Tuesday, is Apple's answer. It builds a strength plan around the equipment you actually have and changes it each week based on what you actually lifted.

It's available now in the iOS 27.3 and iPadOS 27.3 betas, according to 9to5Mac, and it's included in a Fitness+ subscription at no extra cost.

How the plans work

You start by telling it your strength goals, your experience level, your schedule and the equipment you can use. Gym Strength turns that into a four week plan. You pick which days you train and which parts of your body you want to focus on, then choose how long each session runs: five exercises for a workout of about 20 to 30 minutes, or seven for about 45 to 60.

Each workout lists the exercises with recommended sets, reps and weight. There's no class to keep up with. You move at your own pace, and each exercise has a short demonstration video from a Fitness+ trainer that you can watch from three angles. If a machine is taken or your gym doesn't have it, you can swap the equipment or pick an alternative exercise.

The part that makes it more than a workout library is what happens after each week. The next week adjusts to the reps and weight you logged, so the plan moves up when you're ready and holds back when you're not.

What equipment you need

Gym Strength covers more than 350 exercises across more than 30 kinds of equipment, including dumbbells, kettlebells, suspension trainers, cable machines and barbells. Dumbbells are the minimum. Plans adjust for a full commercial gym or a home setup, so a pair of adjustable dumbbells in the garage is enough to get started.

Apple Watch and Training Note

You don't need an Apple Watch, but it helps. With watchOS 27.3 you can see each exercise and log reps and weight from your wrist, which beats juggling a phone between sets, and the watch tracks heart rate and calories along the way.

Apple is also adding Training Note, an optional Apple Intelligence feature that previews each workout, explains why your plan is progressing the way it is, and calls out milestones. It needs an iPhone or iPad that supports Apple Intelligence, set to English.

What it costs and when you can get it

Gym Strength is part of Fitness+, which costs $9.99 a month or $79.99 a year in the US, and it's also included in Apple One Premier at $39.95 a month. New subscribers get a month free, and buying an eligible Apple device comes with three months.

You'll need iOS 27.3 or iPadOS 27.3, which is in developer beta now. Apple has said iOS 27.3 will be released to everyone in December, and that's when most people will see Gym Strength in the Fitness app. Fitness+ is available in 49 countries and regions, and Apple hasn't said whether Gym Strength launches in all of them at once.

Where it fits

Gym Strength lands in the same release as Apple's redesigned Health app, which gives Apple Watch Series 12 and Ultra 4 owners a daily readiness score meant to tell you whether to push harder or rest. One tells you whether today is a good day to lift, and the other tells you what to lift. Apple hasn't said whether the two will talk to each other, and that's the thing to watch when iOS 27.3 ships. If your readiness score could shape what Gym Strength asks of you that day, it would start to look like a real coach rather than a plan that only reacts once a week.
