Personal training app

A plan built around you, like a trainer would

A good trainer starts by asking questions. The app does the same: your goal, experience, training days, session length, equipment and the areas you want to focus on. From your answers it builds a complete program with the right split, exercises and number of sets.

  • Goal, level, schedule and equipment as the starting point
  • A recommended training split based on your answers
  • Priority Zones for up to two areas you want to improve most
Asking the AI coach to compare this month with last month in the GrabGains app

AI personal trainer app

A coach you can ask anything about your training

Coach Adam (or Coach Emma, depending on your profile) is the AI coach inside the app. Ask it to compare this month with last month, explain what changed in your training or suggest what to focus on next. Its answers are based on your own workouts, your plan and your latest reviews, not on a generic template. If it suggests swapping an exercise, nothing changes until you tap Apply.

The coach is a language model: it can be wrong and does not give medical advice. See a doctor about health complaints. GrabGains provides general fitness information and is not a medical service.

  • Answers based on your own workout logs
  • Weekly Review and Monthly Deep Dive one tap away
  • Available whenever you train, early or late

Virtual personal training

Check-ins that show how it's really going

Every Monday the coach sums up your past training week, and on the 1st of each month the month before: volume, training time and workouts compared with the period before, and how your sessions felt. The Monthly Deep Dive also shows where your sets went across your muscle groups and ends with a concrete point to work on for the weeks ahead.

  • Weekly Review of your past training week
  • Monthly Deep Dive with a comparison to last month
  • A clear focus point for the weeks ahead

Exercise guidance

Know how to do every exercise

A trainer shows you the movement before you load the bar. In the app, exercises come with a demo, step-by-step instructions and an overview of the muscles they work, plus a video guide where available.

Has a physiotherapist or other expert reviewed an exercise? Then the app shows who checked it.

  • Step-by-step instructions on how to perform the exercise
  • Reviewed by a physiotherapist or other expert, shown in the app
  • Target muscles shown front and back

Online personal trainer app

A plan that adapts when you do

Prefer a lat pulldown over pull-ups, or a machine over a barbell? Tell the app when you set up your plan, or swap an exercise later and choose "always": it remembers your choice for your next plan.

Every four weeks a training block ends. The app looks at how it went and most of your main lifts move on to a new variant. If your lifts stalled or you trained less than planned, the coach can propose a lighter week or fewer training days, which only applies once you tap Apply.

  • Swap exercises for an alternative you prefer
  • Preferences remembered for your next plan
  • A new block every four weeks, with a look at how the last one went

Frequently asked questions

What is the best personal trainer app?

The best personal trainer app builds a plan around your goal and schedule, shows you how to do every exercise and gives you feedback on your progress. GrabGains combines Smart Workouts, exercise guidance and an AI coach that reviews your training and answers your questions.

Can an app replace a personal trainer?

An app can take over a large part of what a trainer does: planning your workouts, guiding your technique and tracking your progress. What it can't do is watch you train in person. The coach is a language model: it can be wrong and does not give medical advice. See a doctor about health complaints. GrabGains provides general fitness and training information only and is not a medical service. Consult a healthcare professional before starting a new training program.

Is there a free personal trainer app?

GrabGains is free to download, and new accounts get GrabGains Pro free for 14 days. After that, Basic stays free: logging workouts, the exercise library, the feed, leaderboards and your PRs. Generating Smart Workouts, the AI coach with its weekly and monthly reviews, Muscle Zone Tracking and the other Pro features need a subscription. Pro prices for your country are shown in the App Store and Google Play. Subscriptions renew automatically until you cancel in your App Store or Google Play account settings, at least 24 hours before renewal.

How does the AI personal trainer work?

The AI coach (Coach Adam or Coach Emma) uses your profile, your active plan, your recent workouts and your latest reviews to answer your questions, such as how this month compares with last month or what to focus on next. Every Monday you get a Weekly Review and on the 1st of the month a Monthly Deep Dive. The coach does not build your plan: the app creates it from your answers, so your program stays consistent. The coach replies in English, Spanish or Dutch, matching your app language.

Can I use the app for training at home?

Yes. Enter the equipment you have, from bodyweight only to a full home gym, and your plan is built around it.

Is the personal trainer app available on iPhone and Android?

Yes. GrabGains is available on iOS and Android. Download it from the App Store or Google Play and try Pro free for 14 days.
