Best Strength Training App in Australia: Why 12REPS Is the Smart Choice for Building Muscle

By Will Duru, BSc (Hons) Sport and Exercise Science, Award winning Personal Trainer with over 10 years of experience in strength training

Finding the right fitness app in Australia can feel overwhelming. The App Store and Google Play are flooded with options, each promising transformation. Most deliver generic workouts designed for nobody in particular, created by algorithms rather than qualified trainers.

If you are serious about building muscle and strength, whether training at a gym in Sydney, Melbourne, Brisbane or Perth, or working out at home in your lounge room, you need more than a random exercise generator. You need a personal trainer in your pocket.

That is exactly what the 12REPS app provides.

What Makes 12REPS Different

Most fitness apps fall into two categories: either they offer generic programmes that ignore your individual needs, or they provide tracking tools without actual guidance on what to do.

12REPS combines both. You get structured programmes designed by a certified personal trainer, complete tracking to monitor your progress and the flexibility to create your own workouts when you want to train your way.

A Real Personal Trainer, Not an Algorithm

The programmes in 12REPS are created by Will Duru, a certified personal trainer with a BSc in Sport and Exercise Science and over 10 years of experience helping real people build muscle and strength.

This is not AI-generated content. This is not a random exercise database. Every programme reflects genuine expertise, the kind you would receive from hiring a personal trainer, but accessible through your phone at a fraction of the cost.

In Australia, personal training sessions typically cost between $80 and $150 per hour. Training three times weekly adds up to $960 to $1,800 monthly. The 12REPS app provides expert programming for less than the cost of a single session.

Video Guidance for Every Exercise

Each exercise in the app includes video demonstrations showing proper technique. You see exactly how movements should be performed, not just their names on a list.

This matters whether you are a beginner learning the basics or an experienced lifter refining your form. Proper technique prevents injury and ensures the right muscles receive the intended stimulus.

The videos are clear, professionally produced and designed to be followed easily during your workout.

Works at Any Gym or at Home

Australian gyms vary widely in equipment. A premium fitness centre in Sydney’s CBD has different offerings than a local gym in the suburbs or a 24-hour facility in regional Queensland. Your home setup might include just dumbbells and a bench, or perhaps a full garage gym.

12REPS adapts to your situation. The app includes programmes for:

  • Full gym access: Comprehensive programmes using barbells, dumbbells, cables and machines
  • Limited equipment: Effective workouts when your gym lacks certain tools
  • Home training: Bodyweight and minimal equipment programmes for lounge room or garage workouts
  • Hybrid training: Combining gym and home sessions based on your schedule

You tell the app what equipment you have access to, and it provides appropriate programming. No more arriving at the gym only to discover the programme requires equipment you do not have.

Create Your Own Workouts

While expert-designed programmes form the foundation, 12REPS also lets you build custom workouts. Perhaps you have specific exercises you prefer, or you want to design sessions around your gym’s unique equipment.

The app provides access to over 1,500 exercise demonstrations. Select your movements, set your parameters and create workouts tailored exactly to your preferences.

This flexibility means the app grows with you. Follow structured programmes when you want guidance, create your own when you want control.

Progressive Overload Built In

The fundamental principle of muscle and strength building is progressive overload: gradually increasing demands on your muscles over time. Without progression, results stall.

12REPS tracks every workout. You see what weight you lifted, how many reps you completed and how that compares to previous sessions. The app guides you toward appropriate increases rather than leaving progression to guesswork.

This systematic approach produces consistent results. You are not just exercising randomly. You are following a structured path toward your goals.

Why Aussies Are Choosing 12REPS

Fits the Australian Lifestyle

Australia offers a unique lifestyle that balances fitness with outdoor activities. Many Aussies surf, swim, play weekend sport or enjoy hiking and beach activities. You want gym training that complements these pursuits rather than leaving you too wrecked to enjoy them.

12REPS programmes can be adjusted based on your other activities. Playing rugby or AFL on weekends? The app helps build the strength and power you need without overtraining. Want to maintain muscle while prioritising surfing during summer? Flexible scheduling accommodates your lifestyle.

Whether you train early before work to beat the heat, during lunch breaks or in the evening after the temperature drops, the app fits your schedule.

Perfect for Aussie Gym Culture

Australian gym culture is straightforward and no-nonsense. You want to get in, train hard and get results without complicated gimmicks or trendy nonsense.

12REPS matches this approach. No dancing workouts. No confusing periodisation schemes. Just solid programming based on proven principles: compound movements, progressive overload and consistent effort.

The app respects your time and intelligence. It tells you what to do, shows you how to do it and tracks your progress. Simple, effective and results-focused.

Works Across All Time Zones

With gyms spread from Perth to Brisbane, covering three time zones, Australians need an app that works on their schedule. 12REPS does not require live classes or scheduled sessions. Your programme is available whenever you are ready to train, whether that is 5am in Melbourne or 9pm in Darwin.

The app works offline once downloaded, perfect for gyms with dodgy WiFi or training while travelling in regional areas.

What You Get With 12REPS

Structured Training Programmes

Choose from programmes designed for different goals:

Muscle Building: Hypertrophy-focused programmes using proven rep ranges, volumes and exercise selections to maximise muscle growth.

Strength Development: Programmes emphasising progressive loading on compound movements to build raw strength.

General Fitness: Balanced approaches combining strength, muscle and conditioning for overall health.

Home Workouts: Effective programmes requiring minimal or no equipment, perfect for garage gyms or apartment training.

Each programme specifies exactly what to do: exercises, sets, reps, rest periods and progression guidelines. No guesswork required.

Exercise Library

Access over 1,500 exercises with video demonstrations. Each video shows:

  • Starting position
  • Movement execution
  • Common mistakes to avoid
  • Target muscles

This library supports both following programmes and creating custom workouts.

Workout Tracking

Every session is recorded automatically. Review your history to see:

  • Weights used for each exercise
  • Reps completed
  • Personal records achieved
  • Progress over weeks and months

This data informs future training decisions and provides motivation as you watch your numbers climb.

When you want to train your way, the custom workout builder provides complete control. Select exercises from the library, set your parameters and save workouts for repeated use.

Combine exercises into supersets. Add notes for specific cues. Build the exact sessions you want.

Comparing 12REPS to Other Options

Versus Generic Fitness Apps

Most popular fitness apps offer quantity over quality. Thousands of workouts that nobody specifically designed for results. Random variety that prevents progressive overload. No qualified trainer behind the programming.

12REPS provides fewer programmes but each is properly structured by an expert. Quality over quantity produces better results.

Versus AI-Generated Plans

ChatGPT and similar tools can generate workout lists, but they lack tracking, progression systems and video guidance. They produce static templates rather than evolving programmes.

12REPS combines human expertise with technological convenience. The programming comes from a real trainer. The delivery uses modern app capabilities.

Versus Hiring a Personal Trainer

Personal training provides benefits 12REPS cannot: real-time technique correction, hands-on spotting and in-person motivation.

But personal training costs $80 to $150 per session in Australia. Three sessions weekly totals $960 to $1,800 monthly. Many Aussies cannot afford this, or cannot commit to fixed appointment times.

12REPS provides expert programming at a fraction of the cost. For many people, this represents the best value proposition: professional guidance without professional prices.

The ideal approach often combines both: occasional trainer sessions for technique assessment and form checks, with 12REPS guiding daily training between appointments.

Getting Started

Downloading and starting with 12REPS takes minutes:

Step 1: Download the app from the App Store or Google Play.

Step 2: Create your profile, including your available equipment and training preferences.

Step 3: Select a programme matching your goals, or explore the exercise library to build custom workouts.

Step 4: Start training with video guidance and automatic tracking.

Step 5: Progress systematically as the app guides you toward increased weights and reps.

Real Results for Real People

The proof of any training approach is results. 12REPS users consistently report:

  • Strength gains they never achieved with random gym sessions
  • Muscle development they thought required expensive personal training
  • Consistency improvements from having clear daily guidance
  • Confidence in their training approach knowing it was designed by an expert

These outcomes stem from proper programming, systematic progression and the accountability that tracking provides.

What You Actually Need

Forget the generic apps. Forget asking ChatGPT to write you a programme. Here is what you actually need to build muscle and strength:

A weekly programme designed by certified coaches. Not an algorithm. Not AI-generated templates. Real programming from qualified trainers who understand how to structure training for results.

Exercise demos and video technique breakdowns so you know what you are doing. Every movement explained clearly so you can execute with confidence and avoid the form errors that lead to injury and wasted effort.

Over 1,500 exercises for you to plan and create your own workout splits. Complete flexibility to build custom sessions when you want to train your way, with professional demonstrations for every movement.

Rehab exercise videos from a certified personal trainer and physio to guide you to full recovery. When niggles happen, you have expert guidance to work through them safely rather than guessing or making things worse.

This is what separates real progress from spinning your wheels.
