By Alex 9 min read

Chair lunges are a versatile lower body exercise that utilizes a chair for support or depth, making lunges accessible for varying fitness levels while building strength, stability, and proper form.

How to do chair lunges?

The chair lunge is a highly effective, modifiable lower body exercise that utilizes a chair for either support, balance, or as a depth target, making it accessible for varying fitness levels while building foundational strength, stability, and proper lunge mechanics.


What Are Chair Lunges?

The chair lunge is a variation of the traditional lunge, designed to enhance stability, control, and depth awareness. It involves performing a lunge movement while either holding onto a chair for balance or using the chair as a tactile cue for the depth of your rear knee or the lowering of your glutes. This modification is particularly valuable for individuals new to lunging, those with balance challenges, or anyone looking to refine their lunge form before progressing to more advanced variations.

Muscles Worked

Chair lunges are a compound exercise primarily targeting the muscles of the lower body, while also engaging core stabilizers.

  • Quadriceps: Located at the front of the thigh (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). These muscles are heavily involved in knee extension during the ascent phase and control knee flexion during the descent.
  • Hamstrings: Located at the back of the thigh (biceps femoris, semitendinosus, semimembranosus). They work eccentrically to control the descent and concentrically to assist in hip extension during the ascent.
  • Gluteal Muscles: Primarily the gluteus maximus, but also the gluteus medius and minimus. These are crucial for hip extension and external rotation, especially as you push back up from the lunge. The gluteus medius and minimus also play a key role in stabilizing the hip and preventing knee collapse.
  • Adductor Magnus: A large muscle on the inner thigh that assists in hip extension and stabilization.
  • Calves (Gastrocnemius and Soleus): Provide ankle stability and contribute to the push-off.
  • Core Stabilizers (Rectus Abdominis, Obliques, Erector Spinae): These muscles work isometrically to maintain an upright torso and prevent excessive spinal movement throughout the exercise.

Step-by-Step Instructions

Executing chair lunges with proper form is crucial to maximize benefits and minimize injury risk.

  1. Preparation:

    • Choose Your Chair: Select a sturdy, stable chair or bench that will not slide. For balance support, place the chair beside you. For depth targeting, place the chair directly behind you.
    • Starting Stance: Stand tall with your feet hip-width apart. Engage your core by drawing your navel towards your spine.
    • Leg Placement: Step one leg forward, approximately 2-3 feet, creating a staggered stance. Your front foot should be flat on the floor, and your rear foot should be on the ball of your foot, with the heel lifted. Ensure your front knee is stacked directly over your ankle.
  2. Execution - The Descent:

    • Lowering Phase: Inhale as you slowly lower your body straight down towards the floor. Focus on bending both knees simultaneously.
    • Front Leg Form: Keep your front shin as vertical as possible, ensuring your front knee tracks in line with your second and third toes and does not collapse inward or outward.
    • Rear Leg Form: Allow your rear knee to descend towards the floor. If using the chair for depth, gently tap your glutes to the chair or lower until your rear knee is just above the floor (or gently touches it if using for a depth target).
    • Torso Posture: Maintain an upright torso throughout the movement, keeping your chest lifted and shoulders back. Avoid leaning excessively forward or backward.
  3. Execution - The Ascent:

    • Pushing Up: Exhale as you powerfully drive through the heel of your front foot and the ball of your rear foot to push back up to the starting position.
    • Muscle Engagement: Focus on squeezing your glutes and quads in your front leg to initiate and complete the upward movement.
    • Controlled Movement: Avoid using momentum. The ascent should be controlled, mirroring the controlled descent.
    • Return to Start: Bring both feet back together to the starting hip-width position, or maintain the staggered stance for continuous repetitions on one side before switching.

Common Mistakes to Avoid

  • Knee Caving In/Out: Allowing the front knee to drift inward or outward.
    • Correction: Actively push your front knee slightly outward, ensuring it tracks directly over your second and third toes. Focus on engaging your gluteus medius.
  • Leaning Too Far Forward: Rounding your back or excessively hinging at the hips.
    • Correction: Keep your chest up, shoulders back, and core engaged. Imagine a string pulling you upwards from the crown of your head.
  • Insufficient Depth: Not lowering enough to fully engage the leg muscles.
    • Correction: Aim for at least a 90-degree bend in both knees, or until your rear knee is close to the floor (or touches the chair, if used as a target).
  • Using Momentum: Bouncing out of the bottom of the lunge or using excessive speed.
    • Correction: Slow down the movement. Focus on controlled descents and powerful, deliberate ascents.
  • Narrow Stance: Placing feet too close together, compromising balance.
    • Correction: Ensure your feet are hip-width apart in your staggered stance, as if on two separate "train tracks," not on a tightrope.

Benefits of Chair Lunges

  • Enhanced Stability and Balance: The chair provides a point of support, allowing individuals to focus on movement mechanics without the primary concern of losing balance.
  • Improved Form and Technique: Using the chair as a depth guide helps establish proper range of motion and ensures consistent lunge depth, which is crucial for muscle activation.
  • Reduced Joint Impact: Compared to dynamic lunges or jump lunges, chair lunges are performed with greater control, reducing stress on the knees and ankles.
  • Unilateral Strength Development: Like all lunge variations, chair lunges challenge each leg independently, addressing muscular imbalances between sides.
  • Accessibility: This modification makes lunges accessible to a broader population, including beginners, older adults, or those recovering from certain injuries (with medical clearance).
  • Foundation for Progression: Mastering chair lunges builds the necessary strength, coordination, and proprioception to advance to traditional lunges, walking lunges, or even weighted lunges.

Variations and Progressions

Once you've mastered the basic chair lunge, you can explore various modifications to increase or decrease the challenge:

  • Easier:
    • Chair for Balance Only: Hold onto the back or side of a chair with one or both hands for support while performing the lunge.
    • Reduced Depth: Only lower part-way until you feel comfortable and stable.
  • Harder:
    • Chair as Depth Target Only: Perform the lunge without holding the chair, simply using it as a tactile cue for your glutes or rear knee.
    • Increased Depth: Lower deeper, if comfortable and your form allows, potentially aiming for your rear knee to lightly touch the floor.
    • Holding Light Weights: Once bodyweight form is perfect, hold a light dumbbell or kettlebell in each hand, or a single weight in the goblet position.
    • Tempo Training: Slow down the eccentric (lowering) phase (e.g., 3-5 seconds down) to increase time under tension and muscle engagement.
    • Rear Foot Elevated Split Squat (Bulgarian Split Squat): This is a significant progression where your rear foot is elevated on a bench or chair, drastically increasing the challenge to the front leg and glutes.

Who Should Do Chair Lunges?

Chair lunges are an excellent exercise for a diverse range of individuals:

  • Beginners: Ideal for learning the fundamental movement pattern of a lunge and building initial lower body strength and balance.
  • Individuals with Balance Concerns: The added stability of the chair makes lunges safer and more confidence-inspiring.
  • Rehabbing Individuals: Under the guidance of a physical therapist, chair lunges can be a controlled way to regain strength and range of motion after lower body injuries.
  • Older Adults: Provides a safe and effective way to maintain lower body strength, improve balance, and support functional movements.
  • Those Focusing on Form: Even experienced lifters can use chair lunges to perfect their lunge mechanics, identify imbalances, or as a warm-up.

Safety Considerations and When to Consult a Professional

While generally safe, it's important to approach chair lunges mindfully:

  • Listen to Your Body: Stop immediately if you experience sharp pain in your knees, hips, or back. Mild muscle fatigue is normal, but pain is a warning sign.
  • Proper Footwear: Wear supportive athletic shoes that provide good grip and stability.
  • Stable Surface: Ensure your chair is on a non-slip surface and is stable enough to support your weight or provide reliable balance.
  • Pre-Existing Conditions: If you have any pre-existing knee, hip, back, or balance issues, consult with a physician or a qualified physical therapist before incorporating chair lunges into your routine. They can provide personalized advice and modifications.
  • Professional Guidance: If you're unsure about your form, consider working with a certified personal trainer or kinesiologist. They can provide real-time feedback and ensure you're performing the exercise correctly.

Integrating Chair Lunges into Your Workout

Chair lunges can be a versatile addition to various workout routines:

  • Warm-up: Perform 1-2 sets of 10-12 repetitions per leg at a moderate pace to prepare your lower body for more intense exercises.
  • Main Strength Work: Include 2-4 sets of 8-15 repetitions per leg as part of your lower body strength training day. Adjust repetitions based on your goals (higher reps for endurance, lower reps with added weight for strength).
  • Accessory Work: Use them to target specific muscle groups or to address muscular imbalances at the end of a workout.
  • Circuit Training: Incorporate chair lunges into a circuit with other exercises for a full-body or lower-body conditioning workout.
