Split squats and lunges are two of the most effective lower-body exercises for building strength, stability, and mass. Both exercises target multiple muscle groups simultaneously, making them staples in various strength training routines.
However, when it comes to determining which exercise reigns supreme, the debate between split squats and lunges often arises. As we examine each exercise in detail, we will compare its benefits, variations, and suitability for different levels of fitness.
The key difference between split squats and lunges lies in their movement dynamics and stability requirements: split squats involve a stationary stance, while lunges require stepping, which changes muscle activation and balance demands.
By the end, you’ll have a clearer understanding of whether split squats or lunges better align with your fitness goals and preferences.
Introduction to Leg Workouts
Leg workouts are essential for building a strong, balanced, and functional lower body. Incorporating exercises that target multiple muscle groups not only improves overall strength and endurance but also supports athletic performance and daily activities.
Among the most effective movements for leg workouts are split squats and lunges. Both exercises engage similar muscle groups—including the quadriceps, hamstrings, glutes, and calves—while offering unique benefits and challenges.
Additionally, both exercises require little to no equipment, making them accessible for beginners. Understanding the differences between split squats and lunges can help you design a workout routine that aligns with your fitness goals, whether you’re aiming to build muscle, increase stability, or enhance functional strength.
In this article, we’ll break down the key differences, benefits, and best practices for integrating split squats and lunges into your training program, so you can get the most out of every leg day.
What is a Split Squat?
A split squat is a stationary lower-body exercise performed in a split stance, which mimics the lunge movement pattern but with one foot fixed in place. It primarily targets the quadriceps, hamstrings, glutes, and calf muscles, with additional activation of the core and stabilizing muscles.
Split squats are ideal for addressing muscle imbalances and asymmetries, as each leg works independently.
How Split Squat Muscles Worked?
Split squats work several major muscle groups in the lower body, with emphasis on either the glutes or quads depending on your stance and technique.
- Quadriceps: The muscles at the front of the thigh, including the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius, are heavily engaged to extend the knee during the upward phase of the split squat.
- Gluteus Maximus: The largest muscle in the buttocks, the gluteus maximus, is responsible for hip extension, contributing to the upward movement of the body during split squats.
- Hamstrings: The muscles at the back of the thigh, including the biceps femoris, semitendinosus, and semimembranosus, assist in knee flexion and hip extension, supporting the movement pattern of split squats.
- Adductors: The muscles located on the inner thigh, such as the adductor longus, adductor brevis, and adductor magnus, help stabilize the lower body and maintain proper alignment during split squats.
- Calves: The gastrocnemius and soleus muscles of the calf are activated to stabilize the ankle joint and provide support during the split squat movement.
Split Squat Benefits
Split squats hold several advantages over lunges:
- Stability and Control: With one foot fixed on the ground, split squats allow for better stability and control of movement, reducing the risk of injury. Split squats require less balance than lunges, making them more stationary and easier to manage for most people.
- Isolation of Muscles: By focusing on one leg at a time, split squats enable targeted muscle activation, facilitating strength gains and muscle symmetry.
- Joint-Friendly: The stationary nature of split squats minimizes impact on the knees and lower back, making them suitable for individuals with joint issues or mobility limitations.
- Progressive Overload: Split squats can be easily progressed by adding weight or adjusting the height of the rear foot, providing continuous challenges for strength development.
What are Lunges?
Lunges are dynamic lower-body exercises that involve stepping forward, backward, or to the side while maintaining an upright posture. A forward lunge is a fundamental variation that requires a step forward, emphasizing single-leg strength and balance.
They primarily target the quadriceps, hamstrings, glutes, and calf muscles, with additional engagement of the core for stability. Lunges can be performed in various directions and with different variations, such as the walking lunge, which is a dynamic variation involving continuous movement across space.
Other variations include the curtsy lunge, which targets the hip muscles through controlled, side-to-side movement, providing versatility and scalability for individuals of all fitness levels.

What Muscles Do Lunges Work?
- Quadriceps: Like split squats, lunges heavily target the quadriceps muscles, particularly during the downward phase of the movement when the knee is flexed. Lunges target every leg muscle, including stabilizers, ensuring comprehensive lower body development.
- Gluteus Maximus: Lunges also engage the gluteus maximus to a significant extent, especially during the upward phase when pushing off the front foot to return to the starting position.
- Hamstrings: While not as prominently engaged as in split squats, the hamstrings contribute to knee flexion and hip extension during lunges, particularly in the rear leg.
- Adductors: The adductor muscles play a role in stabilizing the hips and maintaining proper alignment during lunges, especially during lateral or reverse variations. In a reverse lunge, you step back with the opposite leg, then lower your body and push back to the starting position.
- Core Muscles: Lunges require core stability to maintain an upright posture and prevent excessive leaning or twisting during the movement, engaging muscles such as the rectus abdominis, obliques, and erector spinae. Lunges also activate stabilizer muscles, which help maintain balance and joint stability throughout the exercise. It is important to keep the torso upright during lunges to ensure proper form and reduce strain on the knees. Retracting the shoulder blades helps maintain good posture and prevents hunching forward.
- Hip Flexors: The hip flexor muscles, including the iliopsoas and rectus femoris, are actively engaged to stabilize the pelvis and support the movement of the front leg during lunges. Hip flexion plays a key role in lunges, as increased hip flexion angles can enhance muscle engagement and deepen the exercise’s difficulty.
When performing lunges, aim to bring the back knee as close to the ground as possible to maximize muscle engagement and range of motion.
Benefits of Lunges
Lunges offer distinct advantages compared to split squats:
- Dynamic Movement Patterns: Lunges involve multi-directional movement, enhancing coordination, balance, and functional fitness for activities of daily living. Lunges also mimic everyday movements such as climbing stairs, making them highly functional.
- Core Activation: The dynamic nature of lunges engages the core muscles to a greater extent, improving overall stability and posture.
- Cardiovascular Benefits: The repetitive nature of lunges increases heart rate and oxygen consumption, promoting cardiovascular health and endurance.
- Variety of Variations: Lunges can be performed in different planes of motion and with various equipment, allowing for endless variations to prevent workout plateaus.
- Strength and Muscle Development: Lunges are compound exercises that target multiple muscle groups at once. As a unilateral exercise, lunges help correct muscle imbalances and develop unilateral leg strength. They are effective for building muscle and gaining muscle, especially when performed with progressive overload. Lunges also contribute to increasing muscle mass, which is important for strength, power, and overall athletic performance. Both exercises are highly functional and mimic everyday movements such as walking and climbing stairs.

Difference Between Split Squat and Lunge?
Both the split squat and both the lunge are effective leg exercises that can be incorporated into your leg day routine. As unilateral exercises, they each offer unique benefits for muscle group targeting, balance, and strength development.
Including both in your program, along with other leg exercises, can help ensure comprehensive lower body training.
Split Squats | Lunges | |
|---|---|---|
1. Stability and Control: | Split squats require less balance and offer greater stability and control compared to lunges because the feet remain stationary in a staggered stance throughout the movement. This makes split squats particularly beneficial for those who have balance issues or are new to strength training. The static nature of split squats also distinguishes them from bilateral exercises, which train both sides simultaneously. | Lunges involve a dynamic movement pattern with a staggered stance where the body moves through space, requiring more coordination and balance. For beginners or individuals with stability issues, lunges can enhance proprioception and functional fitness. Lunges are unilateral exercises, in contrast to bilateral exercises. |
2. Muscle Activation: | Split squats primarily target the quadriceps, hamstrings, glutes, and calf muscles—engaging every muscle group in your lower body. As a single leg, unilateral exercise, split squats help address muscle imbalances and asymmetries. Lunges split squats both target similar muscle groups, making them effective for lower body development. | Lunges emphasize hip stability and core activation due to their dynamic nature, while split squats target the same muscle groups. Hip stabilizing muscles may also be more engaged during lunges. Both exercises are unilateral exercises, focusing on one leg at a time and helping to correct muscle imbalances. |
3. Range of Motion: | Split squats have a decent range of motion, but they are typically shorter than lunges because the rear foot remains elevated on a bench (foot elevated variation). Keeping the front foot flat is important for proper form. If you are recovering from a knee injury or have limited hip mobility, this can be beneficial. | Lunges offer a greater range of motion as the forward leg moves through a larger stride, allowing for deeper knee flexion and hip extension. This increased range of motion can help improve flexibility and mobility in the lower body. |
4. Joint Stress: | Because split squats are a stationary exercise, they generally place less stress on the knees and lower back compared to lunges, making them a safer option for individuals with joint issues or mobility limitations. | The lunge involves a more dynamic movement pattern that may increase stress on knees and hips, especially if performed incorrectly. Proper form and control are essential to minimize the risk of injury during lunges. |
5. Progression and Variation: | Split squat variations, such as Bulgarian split squats (foot elevated) and deficit split squats, can further increase the difficulty. Split squats allow you to lift heavier weights due to the stable position, and can be performed with just your body weight or added resistance. Keeping the foot flat is crucial for safety and effectiveness. These important leg exercises can be progressed by adjusting load or stance. | Lunges offer a wide variety of variations, including forward lunges, reverse lunges, lateral lunges, walking lunges, and jumping lunges. Both exercises can be performed with body weight or added resistance, making them accessible for all fitness levels. Just your body weight is enough to get started with lunges, and they remain a staple among leg exercises. |
When designing your program, consider how both the split squat and the lunge fit into your leg day routine. You may choose split squats for their stability and ability to lift heavier weights, or lunges for their dynamic movement and functional benefits.
Including both, along with other leg exercises, ensures balanced development and addresses every muscle group in your lower body.
