Beginner 4-Day Strength Split: Lose 18kg with Push/Pull/Legs | 12Reps

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

The desire for change, the longing for a healthier, stronger body, but also the fear and intimidation of the unknown. That’s exactly where Bala found himself at 36. He had never trained before, never participated in any sport, and the gym felt like a foreign land. But Bala’s story is not one of fear, it’s one of transformation. It’s a story of how he shed 18kg of body fat, built a body he is proud of, and conquered his gym-phobia. And it all started with a simple, yet effective, 4-day strength-training split.

This article is for anyone who feels like Bala did. For anyone who is a beginner at the gym and wants to burn fat over the next 12 months. I’m Will Duru, and with over 10 years of experience in strength training and recovery, I’m here to guide you on your own journey. We’ll delve into the exact program that helped Bala achieve his incredible results, a program built on a foundation of push/pull/legs and interval cardio. We’ll also explore the crucial role of nutrition, especially for those following a vegan diet, and how the 12Reps app can be your ultimate companion in this journey.

When Bala first walked into the gym, I saw the apprehension in his eyes. He was a complete beginner, and my first priority was to make him feel comfortable and confident. We didn’t jump straight into heavy lifting. Instead, we focused on building a solid foundation with bodyweight exercises and mobility drills. This initial phase was crucial for preparing his body and mind for the challenges ahead.

For the first month, our focus was on mastering fundamental movements and improving mobility. This phase is about building a strong and stable base, which is essential for preventing injuries and ensuring long-term progress. Here are some of the exercises we incorporated:

Phase 1: Months 2-4 – Building a Strong Base

The first phase of the strength training program focuses on building a strong foundation. The focus is on mastering the correct form for each exercise and gradually increasing the weight. We’re not trying to break any records here; we’re building a body that is resilient and ready for the more intense training that will come later.

Cardio and Core Day

This day is dedicated to improving cardiovascular fitness and strengthening the core. We used interval training on the treadmill to maximise calorie burn and improve Bala’s overall fitness. The workout would look something like this:

  • Warm-up: 5-minute light jog
  • Intervals: 1 minute of high-intensity running followed by 2 minutes of walking. Repeat for 20-30 minutes.
  • Core: 3-4 core exercises of your choice. We focused on exercises that build core strength without putting strain on the lower back. Some of our favorites were planks, side planks, bird-dogs, and dead bugs.
  • Cool-down: 5-minute walk and stretching.

Phase 2: Months 5-8 – Increasing Intensity

By the end of phase 1, Bala was moving with confidence, and his strength had significantly improved. It was time to up the ante. In phase 2, we began increasing intensity by introducing heavier weights and more challenging exercises. The goal was to continue stimulating muscle growth and fat loss, while still prioritising perfect form.

Cardio and Core Day

The cardio and core day remained a staple in Bala’s routine. We continued with the interval training, but we increased the intensity and duration. For example, we might do 2 minutes of high-intensity running followed by 1 minute of walking, and we would extend the total workout time to 30-40 minutes. We also introduced more challenging core exercises like hanging leg raises and cable crunches to further develop his core strength.

Phase 3: Months 9-12 – Advanced Techniques

In the final phase of his 12-month transformation, Bala was a completely different person. He was strong, lean, and confident. He was no longer intimidated by the gym; he owned it. In this phase, we introduced more advanced training techniques to push his body to its limits and maximise his results. We incorporated techniques like drop sets, supersets, and pyramid training to increase the intensity and stimulate new muscle growth.

Cardio and Core Day

In the final phase, we continued with high-intensity interval training (HIIT) on the cardio and core day. We also introduced some variety to keep things interesting. For example, we might do a HIIT session on the rowing machine or the assault bike. The core workouts also became more challenging, with exercises like toes-to-bar and ab rollouts.

Fueling the Fire: A Vegan’s Guide to High-Protein Nutrition

One of the most common questions I get as a trainer is, “Can you build muscle and lose fat on a vegan diet?” The answer is a resounding yes, and Bala is living proof. However, it does require a bit more planning and knowledge to ensure you’re getting all the nutrients your body needs to thrive. When Bala told me he was a vegan, I knew we had to pay special attention to his nutrition. We designed a high-protein vegan nutrition plan to fuel his workouts, promote muscle growth, and support fat loss.

Here are some of the key principles we followed:

  • Prioritise Protein: Protein is the building block of muscle, and it’s essential for recovery and growth. We aimed for a daily protein intake of around 1.6-2.2 grams of protein per kilogram of body weight. To achieve this, we incorporated a variety of high-protein vegan foods into Bala’s diet, such as lentils, chickpeas, tofu, tempeh, edamame, quinoa, and seitan.
  • Supplement Smartly: To help Bala meet his protein goals, we introduced a high-quality vegan clear whey protein supplement. This was a convenient and effective way to boost his protein intake, especially after his workouts. We also made sure he was supplementing with vitamin B12, which is essential for vegans as it’s not found in plant-based foods.
  • Focus on Whole Foods: We built Bala’s diet around whole, unprocessed foods. This meant lots of fruits, vegetables, whole grains, legumes, nuts, and seeds. These foods are not only packed with nutrients but also high in fiber, which helps with satiety and digestion.
  • Reduce Alcohol Intake: We didn’t completely eliminate alcohol, but we did reduce it to a maximum of two glasses of wine or two cocktails per week. Alcohol is high in empty calories and can hinder muscle growth and fat loss. By reducing his intake, Bala was able to save a significant number of calories and improve his recovery.

By following these principles, Bala was able to fuel his body for optimal performance and achieve his fat loss goals without compromising his vegan lifestyle. It’s a testament to the fact that with the right knowledge and planning, a vegan diet can be a powerful tool for transformation.
