Why Do Lunges Hurt More Than Squats? Causes, Benefits, and Alternatives

Lunges and squats are excellent lower-body exercises ^[1], but many people find lunges significantly more painful. If you’ve ever wondered, “Why do lunges hurt more than squats?” you’re not alone.

Let’s break it down and explore why lunges cause discomfort, how they compare to squats and alternative leg exercises, and how to use lunges effectively in your workout routines.

Why Lunges Hurt More Than Squats

The lunge exercise places a unique demand on the body, often leading to discomfort in the knee joint, hip joint, and ankle joints. Here’s why:

• Increased Biomechanical Demand – Unlike squats, lunges involve dynamic movement and unilateral loading, which activates stabilizing muscles like the gluteus medius and core while requiring greater knee and hip flexor engagement.
• Muscle Imbalance – Lunges work one leg at a time, forcing the lead lower extremity to handle most of the load. This can expose weaknesses and tight hips.
• Stride Length and Trunk Position Influence – A longer stride increases joint stress, while a forward-leaning trunk position shifts more pressure onto the lower extremity muscles ^[2].
• More Stability Demands – The single-leg nature of lunges means more balance is required, engaging the gluteus medius and core strength to keep the body upright.
• Performed Incorrectly – Common mistakes, like letting the front knee cave in or stepping too far forward, increase joint pain and make lunges more harmful than beneficial. 

Lunges vs. Squats: Which is Better?

​According to fitness expert Steven, lunges are often perceived as more challenging than squats due to their increased demands on balance, coordination, and unilateral strength. Unlike squats, which involve both legs working simultaneously, lunges require each leg to support the body’s weight independently, leading to greater muscle activation and stabilization efforts.

Both exercises build muscle and improve lower body strength, but each has unique benefits:

Lunges

• Improve unilateral strength, reducing muscle imbalances.
• Enhance athletic performance by mimicking real-life movement patterns.
• Increase joint mobility, particularly in the hip flexors.
• Target the glutes, quadriceps, and hamstrings with added weight or external loading. 

Squats

• Allow heavier loads, leading to greater overall muscle mass development.
• Distribute weight more evenly across both legs, making them a suitable option for individuals recovering from knee or hip issues.
• It is easier to modify for different fitness levels and goals.
• Provide better activation of multiple muscle groups in one exercise. 

Alternative to Squats for Leg Strength

If lunges or squats hurt more or cause discomfort, try these alternative lower-body exercises:

1. Split Squats – Similar to lunges but without stepping forward, reducing knee stress.

2. Leg Curls – Performed using a machine or resistance band, they effectively isolate the hamstrings while minimizing stress on the knee joint when done with proper control.

3. Step-Ups – Mimic a lunge but allow a more controlled stepping forward motion.

4. Glute Bridges – Activate the glutes and hamstrings while avoiding pressure on the hip and knee joints.

Leg Exercises to Avoid

Some exercises may cause more harm than good, especially if you experience joint pain:

1. Deep Squats – While effective, they can increase joint stress if performed incorrectly.

2. Anterior Lunge – If you struggle with knee pain, this variation can place excessive stress on the front knee.

3. Leg Extensions – May strain the knee joint if done with heavy weight or improper form.

4. Sit-Ups – Though a core exercise, sit-ups don’t contribute to leg strength and can lead to lower back discomfort.

Functional Training With Lunges

Despite their difficulty, lunges play an essential role in functional training. They help improve:

• Balance and Stability – Walking lunges and single-leg variations train the body to stabilize better in a standing position.
• Core Activation – Keeping the body upright during a lunge enhances core strength.
• Weight Loss and Muscle Activity – Since lunges engage multiple muscle groups, they can contribute to an overall calorie deficit when combined with a balanced diet and other forms of exercise.
• Injury Prevention – Proper form reduces strain on the knee and hip joints, helping prevent injury. 

Mastering Lunges for Stronger Legs

To perform lunges ^[3] correctly and avoid pain:

• Keep Feet at Hip Width – This prevents unnecessary stress on the knee joint.
• Step Forward with Proper Stride Length – Avoid stepping too far or too short to maintain balance.
• Maintain a Neutral Trunk Position – Keep your body upright to engage the core and prevent lower back strain.
• Control Your Movement – Lower slowly to the lowest point and push through the heel of the front leg.
• Alternate Legs – Work both the right leg and left leg evenly to prevent muscle imbalances. 

Conclusion

Lunges may hurt more than squats, but with proper form and an understanding of their mechanics, they can be a valuable addition to your workout routine. If lunges cause joint pain, consider alternative exercises like split squats or step-ups.

Always listen to your body, focus on proper technique, and consult a personal trainer if needed. Whether you want to lose weight, build muscle, or enhance athletic performance, lunges, and their variations can help you achieve stronger legs while improving overall lower body function.
