Muscle Booster is a workout planning app that positions itself as a pocket personal trainer for home and gym workouts alike.
With a library of over 2,000 exercises and personalised plans built around your goals and available equipment, it has carved out a clear niche in a crowded market.
In this review, I share what it’s actually like to use on a daily basis, including the onboarding experience, workout quality, standout features, and how it compares to other alternatives.
In a hurry? Here’s the bottom line…
Muscle Booster is a well-structured app that works particularly well for beginners and those returning to fitness after a break. The guided workouts are easy to follow, the interface is clean, and the variety on offer is impressive. More experienced lifters may find the personalisation a little shallow, but for those just starting out or looking for structured, flexible training sessions, it’s a fantastic option and worth trying.

Muscle Booster TL;DR
Muscle Booster is a fitness app available on iOS and Android, developed by Welltech. It creates personalised workout plans based on a detailed onboarding questionnaire, covering your goals, fitness level, available equipment, training location, schedule preferences, and any injuries or health conditions.
The app covers strength training, bodyweight workouts, calisthenics, cardio, mobility, and recovery, making it one of the more versatile options in its category.
There is also a built-in meal planning section, though that feels less polished than the workout side of the app.
What I Like About Muscle Booster
Onboarding and Setup
The sign-up process takes around 10 minutes and does a thorough job of understanding your situation before building a plan. You answer questions about your fitness goals, target muscle groups, experience level, equipment access, workout days, available time, and any physical limitations. Once complete, the app generates a personalised programme tailored to your inputs.
It is one of the more comprehensive onboarding flows I have come across, and it shows in the quality of the initial plan you receive.

Workout Structure
Each session is well-organised, with a proper warm-up, main workout, and cooldown built in. The app walks you through every exercise with animated muscle diagrams, written cues, and video demonstrations, so you always know exactly what you should be doing and which muscles you are targeting.
Rest timers are built directly into the session, which removes the need to track time yourself and keeps the workout moving at a structured pace.
Exercise Variety
The exercise library is extensive, with over 2,000 movements spanning home workouts, gym-based training, bodyweight exercises, and more. For each exercise, you can swap to alternatives based on your equipment, which is genuinely useful.
Whether you are training at home with minimal kit or in a fully equipped gym, the app adapts without any friction.
Progressive Overload
One of the more distinctive elements of Muscle Booster is how it handles progression. The app requires you to complete your current workouts before unlocking new ones, which enforces a level of accountability that many apps skip over. As you work through your plan, the difficulty increases in a structured way, pushing you to master movements before advancing.
This approach to progressive overload is simple but effective, particularly for beginners who might otherwise rush ahead before they are ready.
Workout Challenges and Goal-Based Plans
Beyond the core workout plan, the app includes a range of challenges you can join based on your onboarding information. These span fat burning, morning routines, calisthenics, chair workouts, and more. They add variety and give you something to work towards alongside your main programme.
Meal Planning
The app includes a meal planning section with recipes, macro breakdowns, and dietary preferences ranging from vegan to keto to Mediterranean. The recipes are simple to follow and include serving adjustments.
It is not the most in-depth nutrition tool on the market, but for users who want a rough dietary structure to accompany their training, it gets the job done.
Interface and Design
Muscle Booster is clean and intuitive. The layout is straightforward, and navigating between your plan, the exercise library, and your progress is effortless. Even for someone who is not particularly tech-savvy, getting up and running with the app is a smooth experience.
Who is Muscle Booster Best For?
Muscle Booster is a great fit for beginners who want a structured, guided approach to fitness without having to design their own programme. The app removes the guesswork entirely and gives you a clear path to follow from day one.
It is also well suited to people with busy schedules who want efficient, focused sessions. Most workouts fall in the 20 to 30 minute range, making it easy to fit training into a full day.
Users who train in different settings will appreciate the equipment flexibility. Whether you are at home, in the gym, or travelling, the app adjusts the plan to what you have available.
The app also works well for older adults and those managing physical limitations. The chair workouts, injury-conscious programming, and accessible structure make it one of the more inclusive options in the space.

Who is Muscle Booster Not For?
More experienced lifters who want to track their progress in granular detail may find the app limiting. There is no way to log the weight you lifted for each set, which makes it difficult to track strength progression over time in any meaningful way. For anyone following a serious strength programme, this is a notable gap.
The app also lacks any community or social features. There are no leaderboards, no challenges shared with other users, and no coach (human or AI) to interact with. If social accountability and competition are what keep you motivated, Muscle Booster is unlikely to scratch that itch.
How Much Does Muscle Booster Cost?
Muscle Booster is free to download but requires a paid subscription to access the full programme. Pricing options include a weekly, monthly, and annual plan, with the annual plan offering the best value at around $59.99 per year. Monthly plans sit at around $14.99 per month.
There is no free trial, which is probably the biggest barrier for new users. You are committing to a subscription before you have had a chance to properly explore the app, which feels like a missed opportunity given how competitive the fitness app market is. That said, the app often presents a discounted offer during sign-up, so it is worth going through the full onboarding process before paying.
FAQs
Is Muscle Booster free?
Muscle Booster is free to download, but the personalised plans and full workout library require a paid subscription. Unlike many competitors, it does not offer a free trial period.
What types of workouts does Muscle Booster offer?
The app covers strength training, bodyweight exercises, calisthenics, cardio, mobility, and recovery. Workouts are available for home and gym settings, with options for minimal equipment or full gym access.
Does Muscle Booster work without a gym?
Yes. The app is designed to work for home users as well as gym goers. During onboarding you specify your equipment and training location, and the plan adjusts accordingly.
Can I use Muscle Booster if I have an injury?
The onboarding questionnaire asks about injuries and physical limitations, and the app takes these into account when building your plan. There are also specific chair-based and low-impact workouts suited to those with mobility restrictions.
Does Muscle Booster track the weights I lift?
No, and this is one of the more notable limitations of the app. You cannot log the specific weight used for each exercise, which limits your ability to track strength progress over time.
Is Muscle Booster compatible with Apple Watch?
Yes, the app is compatible with Apple Watch and can sync with health apps on your device.
Bottom Line
Muscle Booster is a well-designed, accessible fitness app that delivers real value for its target audience. The onboarding is thorough, the workouts are well-structured, and the exercise variety is excellent. The progressive overload approach is a genuine strength, and the flexibility around equipment makes it practical for a wide range of users.
The lack of a free trial is frustrating, and more advanced users will hit a ceiling fairly quickly without weight logging or deep performance tracking. But for beginners, casual trainers, and anyone who wants a guided, adaptable workout plan without spending hours creating one themselves, Muscle Booster is a strong option.
