The Benefits of Side Lunges for Muscle Targeting and Functional Fitness

Side lunges are an effective exercise that targets multiple muscle groups and improves overall functional fitness.

This blog post explores the benefits of side lunges, examines a study comparing forward and side lunges, and provides insights from an athletic standpoint on incorporating side lunges into your training routine.



Target Muscles of Side Lunges

Side lunges primarily target the following muscle groups:

  • Gluteus Maximus
  • Hamstrings
  • Inner Thigh (Adductor Muscles)
  • Quadriceps


Why Should You Do Side Lunges?

Most traditional exercises, such as squats, forward lunges, and deadlifts, are performed in the sagittal plane (forward and backward movement). However, incorporating frontal plane movements (side-to-side) like side lunges into your workout can enhance overall functionality. Side lunges improve your body’s ability to move laterally, which is crucial for daily activities and sports performance.



Study Overview: Comparing Forward and Side Lunges

Purpose and Hypothesis

The purpose of this study was to measure the force and stress on the patellofemoral joint during forward and side lunges performed on the ground and on a 10 cm platform. The hypotheses were:

  1. The side lunge would generate more force and stress on the knee than the forward lunge at all knee angles.

  2. Lunges performed on the ground would generate more force and stress than those performed on a platform.


Results

Forward Lunge

During the lunge descent and ascent at a 10° knee angle, the forward lunge produced more force and stress on the knee than the side lunge.

Side Lunge

During the descent at knee angles from 40° to 100° and the ascent at knee angles from 50° to 90°, the side lunge produced more force and stress than the forward lunge.

Ground vs. Platform

Lunging on the ground produced more force and stress on the knee than lunging on a platform at knee angles from 40° to 60° during both descent and ascent.


Conclusions

The study concluded that the amount of force and stress on the knee joint varies depending on the type of lunge, the height of the step, and the knee angle. Lunges on the ground generate more force and stress on the knee than those on a 10 cm platform, especially between 40° and 60° knee angles. Side lunges generate more force and stress than forward lunges between 40° and 100° knee angles. This information can help in designing exercise programs that consider knee joint loading.



Athletic Standpoint: Incorporating Side Lunges

When choosing between exercises like deadlifts, squats, hip thrusts, and lunges, it is essential to consider your specific fitness goals:

  • Jumping Higher: Movements like squats and deadlifts, which involve vertical motion, are ideal.

  • Running Faster: Hip thrusts and lunges are excellent choices for improving running speed.


For better agility and explosive power, especially in sports requiring lateral movements, incorporating weighted side lunges into your training routine is beneficial. Side lunges enhance lateral strength and stability, contributing to improved performance in activities that involve quick direction changes and lateral movements.



Conclusion

Side lunges are a valuable addition to any fitness routine, targeting key muscle groups and improving functional fitness. By understanding the biomechanical differences between forward and side lunges and their impact on knee joint loading, you can tailor your workouts to achieve specific fitness goals. Incorporate side lunges to enhance agility, stability, and overall performance.
