3 Day Strength Training Split for Beginner Runners | 12 Week Plan

By Personal Trainer Vijune Penikaite – level 3 qualified 

Hi, I’m Vijune, a personal trainer with 10 years of experience in the fitness industry. For the past three years, I’ve been coaching both men and women in the heart of London, helping them become strong, powerful, and confident. I’ve seen firsthand the incredible transformations that happen when people commit to a structured strength training program. Today, I want to share with you a program that I believe can get you in the best shape of your life, especially if you’re a beginner runner looking to take your performance to the next level.

The Importance of Strength Training for Runners

Many runners believe that the only way to become a better runner is to run more. While running is, of course, essential, strength training is a powerful tool that can significantly enhance your running performance and overall health. Scientific research has consistently shown that resistance exercise improves running economy, which refers to the amount of oxygen consumed at a given speed. A better running economy means you can run faster and longer with less effort. A study published in the journal Sports found that lower limb resistance exercise is highly effective for improving running economy and performance [1].

Strength training also plays a crucial role in injury prevention. Running is a high-impact activity that can put significant stress on your joints and muscles. By strengthening the muscles that support your joints, you can reduce your risk of common running-related injuries like iliotibial band syndrome (ITBS), patellofemoral pain syndrome (PFPS), and Achilles tendinitis. Research suggests that strengthening the muscles around the hips and pelvis can improve biomechanics and reduce the uneven distribution of forces that often leads to these injuries [1].

Furthermore, strength training helps build and maintain muscle mass, which is vital for both men and women. While men naturally have more muscle mass due to higher testosterone levels, women can achieve similar percentage gains in muscle mass with consistent training [2]. Building muscle is not just about aesthetics; it boosts your metabolism, improves bone density, and contributes to long-term health and longevity. So, if you’re looking for a holistic approach to improve your running and overall well-being, incorporating strength training is a non-negotiable.

3-Day Strength Training Split for Beginner Runners

The Push/Pull/Legs (PPL) Split: A Simple and Effective Approach

For beginners, I recommend a 3-day-per-week push/pull/legs (PPL) split. This training method is simple, effective, and allows for adequate recovery between workouts. The PPL split divides your body into three main muscle groups:

  • Push Day: Works the upper body pushing muscles, including the chest, shoulders, and triceps.
  • Pull Day: Works the upper body pulling muscles, including the back and biceps.
  • Legs & Core Day: Focuses on the lower body and core muscles.

This split ensures that you train all major muscle groups throughout the week, promoting balanced muscle development and reducing the risk of overtraining. It’s a fantastic way to build a solid foundation of strength and get your body accustomed to resistance training.

Your 12-Week Transformation: The Program

I’ve designed a 12-week program that will guide you through a progressive strength training journey. This program is divided into three phases, each with a specific focus to help you build strength, increase muscle mass, and enhance your athletic performance. To make your training experience even more seamless, I highly recommend using a strength training app, such as the 12Reps app. This workout tracker app enables you to create your routine, track your progress, and monitor your rest periods with its built-in stopwatch. You can even try it for free with a 7-day trial.

Warm-up (10 minutes)

Before each workout, it’s crucial to prepare your body for the work ahead. A good warm-up increases blood flow to your muscles, improves mobility, and reduces the risk of injury. Choose one of the following cardiovascular exercises:

  • Incline walk on a treadmill
  • Rowing

After your cardio, perform the following mobility stretches:

Reps/Duration

Cat-Cow

World’s Greatest Stretch

5 per side

Hamstring Stretch

30s per side

Cool-down (10 minutes)

After each workout, a cool-down helps your body gradually return to a resting state. It can also aid in recovery and reduce muscle soreness. Choose one of the following:

  • Stairmaster
  • Incline walk on a treadmill

Finisher (Daily)

To maximise your results, I’ve included a daily finisher that you can do every morning before your shower or every evening before bed. This finisher will help you build a strong core and improve your muscular endurance.

The 12-Week Program

This program is designed to be progressive, meaning that you will gradually increase the intensity and challenge as you get stronger.
