There’s no question that we need leg strength for running. However, the type and amount of leg strength a runner has depends greatly on the type of training, difficult of running, and quality of strength training.
Will running make your legs stronger?
Many beginner runners assume that their legs will automatically get stronger just by creating a running habit. And while you do gain some strength simply by running, it’s imperative that most runners add supplemental leg strengthening exercises to their routine.
Relying solely on running to build leg strength often results in the development of muscle imbalances, as it’s easy for some muscles to remain inactive while others compensate. Muscle imbalances can not only result in insufficient strength, but they can quickly lead to injury as well.
5 Strategies to Build Leg Strength for Running
Learning how to appropriately build leg strength for running is crucial for all runners – even those who are simply running recreationally as a way to stay in shape. Incorporating regular leg exercises for runners will help avoid imbalances, prevent injury, and assist in both increasing mileage and speed.
Here are a few simple strategies to use to improve leg strength in order to enhance your running performance and stay healthy over time.
Include leg exercises specifically for runners
The best way to improve and maintain leg strength for running is to incorporate regular strength training. During a strength training workout, runners can benefit greatly from various leg strengthening exercises.
Be sure to strength train at least once a week – whether you dedicate the entire day to a strength workout, or simply add a short 20 – 30 minute workout after finishing a run. Consistency is key when it comes to building leg strength, so be sure to prioritize these workouts and avoid skipping them.
Focus on both large and small muscle groups
It’s tempting to simply add a few squats and lunges and call it good – a mistake that many new runners make. However, when doing so, many crucial running muscles are neglected.
While the larger muscles are certainly important for runners (quads, hamstrings, glutes, etc.), there are also many smaller muscles that play a key role in maintaining leg strength for running. It’s important to strengthen other muscles as well, such as the those in the ankles, shins, calves, and even feet.
Isolate one leg at a time
Another key to building leg strength – which is also commonly forgotten – is to isolate each individual side. Try single leg extensions, single leg bridges, single leg squats and more to really ensure that each side is gaining equal strength.
Regularly test for leg muscle imbalances
Regardless of how diligent you may be with your strength training and running, it is common to develop muscle imbalances in the legs. Testing for these imbalances regularly can help you prevent them from becoming a bigger problem.
As soon as you detect the development of a muscle imbalance, be sure to address it. Focus on strengthening the weaker side and building full body balance.
Complete full body balance exercises
While it’s certainly important for runners to complete leg strengthening exercises, another way to encourage strength is to complete full body balance exercises. While these exercises might not target a single, specific muscle group, they encourage balance and strengthen the legs to stay steady on different terrains during a run.
