3 Best Intermediate Exercises for Stronger Legs

Building stronger legs is essential for improving athletic performance, supporting day-to-day activities, and developing a balanced physique. For intermediate lifters, focusing on compound movements that target multiple muscle groups is key to advancing strength gains.

This article will highlight three exercises ideal for intermediates aiming to boost leg strength and power, with each move supported by research-based insights to ensure optimal gains.

Barbell Back Squat

The barbell back squat is a foundational lower-body exercise, targeting the quadriceps, hamstrings, glutes, and lower back. Intermediate lifters can leverage this exercise for strength gains and to build muscle.

Studies show that the back squat recruits multiple muscle fibres due to its compound nature, making it highly effective for building strength across various muscle groups in the legs and hips (Escamilla et al., 2001).

Execution Tips:

1. Stand with feet shoulder-width apart, toes slightly pointed outward.
2. Position the barbell across your shoulders, gripping it tightly.
3. Engage your core, descend into a squat by bending at the hips and knees, keeping your chest lifted.
4. Lower until your thighs are parallel to the ground or slightly below.
5. Drive through your heels to return to the starting position, fully extending your hips and knees.

A study by Schoenfeld et al. (2016) confirms that squatting deep, where hip crease dips below knee level, maximises quadriceps and glute activation. However, intermediate lifters should focus on maintaining proper form to prevent injury, especially around the knee and lower back.

Benefits of Barbell Back Squat:

• Increased Strength and Muscle Mass: Studies confirm the back squat’s superior role in developing lower body strength due to its involvement of large muscle groups (Schoenfeld, 2010).
• Hormonal Response: Squats promote anabolic hormonal responses such as growth hormone release, which contributes to muscle growth and overall strength (Kraemer & Ratamess, 2005).
• Improved Functional Movement: The squat is a functional exercise that enhances mobility, balance, and coordination, contributing to better performance in sports and daily activities.

Romanian Deadlift

The Romanian Deadlift (RDL) is another excellent exercise for intermediate lifters focusing on strengthening the posterior chain, primarily targeting the hamstrings and glutes.

Unlike the conventional deadlift, the RDL emphasises hip hinge mechanics, which isolates the hamstrings more effectively (Bishop et al., 2019). This focus on the posterior chain is essential for balanced leg development, reducing injury risk in the lower back and knees.

Execution Tips:

1. Start with feet hip-width apart and a barbell in front of you.
2. Grasp the bar with an overhand grip and keep it close to your legs throughout the movement.
3. Engage your core and keep a slight bend in your knees.
4. Hinge at the hips, lowering the bar down along your legs while keeping your back straight.
5. Stop when you feel a stretch in the hamstrings, then return to the starting position by driving your hips forward.

Research shows that the RDL activates the hamstrings significantly more than traditional deadlifts, making it ideal for those aiming to improve hamstring strength and hypertrophy (Ebben et al., 2009). Maintaining proper technique and focusing on a controlled movement ensures maximal engagement of the target muscles while minimising injury risk.

Benefits of Romanian Deadlift:

• Targeted Posterior Chain Development: By isolating the hamstrings, the RDL helps balance anterior (front) and posterior (back) leg muscle development, reducing knee strain and preventing injuries (Kulas et al., 2010).
• Core Stability Improvement: The exercise strengthens the lower back, glutes, and core, which are vital for overall strength and stability in complex movements.
• Enhanced Flexibility and Mobility: The RDL’s focus on hip flexion and extension enhances hamstring flexibility, contributing to better range of motion and athletic performance (McKean et al., 2010).

Bulgarian Split Squat

The Bulgarian split squat is a unilateral exercise, meaning it works one leg at a time, enhancing strength, stability, and muscle symmetry. This exercise particularly targets the quadriceps and glutes while engaging core muscles for balance.

Research suggests that unilateral exercises are valuable for intermediate lifters as they help identify and address muscular imbalances that may limit overall strength and performance (McCurdy et al., 2005).

Execution Tips:

1. Begin by standing a few feet in front of a bench, with one foot resting on the bench behind you.
2. Hold a dumbbell in each hand, or perform the exercise with just your body weight.
3. Lower your body by bending the front knee until your thigh is parallel to the ground.
4. Push through your front heel to return to the starting position.

The Bulgarian split squat creates high levels of quadriceps and gluteal activation due to its one-leg emphasis, which also requires balance and core stability. Research shows that this exercise effectively recruits the gluteus medius, a muscle crucial for hip stability (Willson et al., 2006).

Benefits of Bulgarian Split Squat:

• Improved Muscle Symmetry: By working one leg at a time, this exercise helps correct strength imbalances and asymmetries that often occur with bilateral exercises.
• Enhanced Balance and Core Activation: The exercise recruits core muscles to maintain stability, particularly in the torso, making it beneficial for athletes who rely on balance and control.
• Increased Glute Activation: A study by Boren et al. (2011) confirms that the Bulgarian split squat is among the best exercises for targeting the gluteus maximus, which is vital for lower body power.

Conclusion

For intermediate lifters aiming to strengthen their legs, the barbell back squat, Romanian deadlift, and Bulgarian split squat are three highly effective exercises. Each movement targets specific areas of the leg muscles, ensuring balanced development and reducing the risk of injuries. With consistent practice and proper form, these exercises provide a strong foundation for progressing into more advanced lifting techniques.
