It was a busy afternoon at the gym in the heart of London when I first met Ola. He walked in, weighing 115kg, with determination in his eyes but uncertainty about where to start. He had a fire burning inside him and a goal that seemed both daunting and inspiring: to transform his life and lose 25kg. As a personal trainer with over a decade of experience coaching men and women to unlock their inner strength, I knew that Ola’s journey would require more than just one approach. We combined strength training, HIIT, and boxing to create a comprehensive program that would strip away the excess weight while building lean muscle and cardiovascular fitness.
After months of dedication and hard work, Ola achieved his initial goal of losing 25kg. But I knew that maintaining motivation after reaching such a significant milestone could be challenging. That’s when we set a new goal that would keep him driven and focused: running a half-marathon. We needed something that would challenge him in a completely different way and maintain the momentum. The transition from weight loss to endurance running required a strategic shift in our training approach, but the foundation of strength we had built became the secret weapon that would take his performance to the next level.
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 the secret weapon that can take your performance to the next level. It’s the difference between finishing a race and crushing it. It’s the key to preventing injuries, improving your running economy, and unlocking a new level of power and speed you never thought possible. Just take it from Ola, who not only conquered the Hackney Half but also the London Half Marathon, achieving an incredible time of 1:50. His journey is a testament to the transformative power of combining strength training with running, a journey you can embark on too.
This article will guide you through a 12-week strength training program designed specifically for runners. We’ll delve into the importance of strength training, debunk common myths, and provide you with a detailed, easy-to-follow plan that you can perform at the gym. This program is designed to be used with the 12Reps app, a powerful workout tracker app that will help you stay on track and monitor your progress. Whether you’re a seasoned marathoner or just starting your running journey, this program will help you build the strength, power, and resilience you need to achieve your goals.

The “Why” Behind Strength Training for Runners
Before we dive into the program, let’s talk about why strength training is so crucial for runners. Think of your body as a high-performance vehicle. Your cardiovascular system is the engine, but your muscles, bones, and connective tissues are the chassis, suspension, and tires. If you have a powerful engine but a weak chassis, you’re not going to be able to handle the demands of the road. You’re more likely to break down and get injured.
Strength training helps to:
- Prevent Injuries: Running is a high-impact activity that places significant stress on your joints and muscles. Strength training helps to strengthen your muscles, ligaments, and tendons, making them more resilient to the repetitive stress of running. This can significantly reduce your risk of common running injuries like runner’s knee, shin splints, and IT band syndrome.
- Improve Running Economy: Running economy refers to the efficiency with which your body utilises oxygen at a given pace. The better your running economy, the less energy you expend to run at a certain speed. Strength training, particularly exercises that target the legs and core, can enhance your running economy by increasing muscle power and stiffness, enabling you to generate more force with each stride.
- Increase Power and Speed: Stronger muscles can generate more force, resulting in a more powerful and explosive running stride. This can help you run faster and more efficiently, especially when it comes to hills and finishing sprints.
- Enhance Muscular Endurance: Strength training helps your muscles become more resistant to fatigue, allowing you to maintain your form and pace for longer periods.
