Leg workouts that address asymmetries

Leg Workout to Fix Asymmetries for Bodybuilders Correcting Left AIC and Right Lateralization

By DXTheTrainer

If you’ve ever felt like one leg is stronger, more defined, or just moves better than the other—you're not alone. These differences often come from built-in asymmetries in your body, especially common ones like the Left Anterior Interior Chain (AIC) pattern and right lateralization. These can throw off your physique, performance, and comfort.

If you tend to feel heavier on your right side, lean on your right foot while walking, or feel off-balance during movements like Bulgarian split squats, this leg workout is for you. I’ll break down what’s happening, why it matters, and exactly how to fix it with targeted training.

Understanding Left AIC & Right Lateralization

The Left AIC pattern—often seen with right lateralization—is a biomechanical shift in how your pelvis and spine are aligned and how your legs function. Here’s what’s going on:

Pelvis: Your left pelvis tends to rotate forward and outward (external rotation bias), while your right pelvis tucks in (internal rotation bias). Spine & Sacrum: Your sacrum tilts slightly right, causing your spine to follow with a mild curve. This makes your right leg the default stance leg. Movement Patterns: You’ll likely generate more force through internal rotation on the right and external rotation on the left, which affects how your muscles develop and move under load.

Signs you’re dealing with this pattern:

You stand or walk heavier on your right leg. It’s harder to lift your right knee using your left leg. You shift right during squats or hinges. Uneven development between your left and right quads or glutes.

Need confirmation? Head to my videos on @DXTheTrainer where I demonstrate simple assessments—like the adduction drop test—to help you identify your pattern. Even just lying down, letting your knees fall inward, and comparing how far each side drops can reveal a lot.

Why These Asymmetries Matter

While perfect symmetry isn’t the goal, too much imbalance can:

Lead to chronic pain in your back, knees, or hips. Mess with your stage presence through uneven quads, glutes, or posture. Limit strength gains and joint health by forcing poor movement patterns.

The solution? A smart corrective workout that targets the right muscles on the right side—without going overboard. Let’s fix the issue and build strength that’s both aesthetic and functional.

The Corrective Leg Workout

This 90-minute routine includes breathing drills, corrective warm-ups, and strength-focused exercises designed to rebalance your pelvis and restore muscular symmetry. If your mobility is very restricted, spend more time on the breathing section.

Step 1: Breathing Drills (5–10 minutes)

These drills reposition your rib cage and pelvis, giving you space to access internal rotation and proper muscle sequencing.

1. Left Posterior Capsule Inhibition (2x4 breaths)

Goal: Reorient the left ilium backward

Feel: Left hamstring, inner thigh

2. Hook Lying with Band and Reach (2x4 breaths)

Goal: Open the left posterior ribs and center the sacrum

Feel: Left abs, right-side reach

3. Sidelying Cross Connect (2x4 breaths)

Goal: Drive IR on the left, hike the left pelvis

Feel: Right glute, left inner foot

Step 2: Corrective Warm-Ups (10–15 minutes)

Use these drills to bridge the gap between breathing and heavy lifts.

1. DNS Star (Right Side) – 4 breaths

Goal: Improve late ER on the right

Feel: Right-side activation without dumping into IR

2. Single-Hand Farmer’s Carry (Right Side) – 30s

Goal: Bias the left stance

Feel: Left abs, left hamstring/IR

3. Camperini Deadlift – 1x8

Goal: Posteriorly rotate the left pelvis

Feel: Left hamstring, inner heel

4. Ipsilateral Loaded Split Squat (Left Side) – 1x8

Goal: Drive IR and quad activity on the left

Feel: Left quad and adductors

5. Step Down (Left) – 1x8

Goal: Promote controlled IR

Feel: Left inner heel, hamstring

6. Step Down (Right) – 1x8

Goal: Enhance ER on the right

Feel: Right glute, left-side obliques

Step 3: Main Strength Training (45–60 minutes)

These lifts maintain pelvic neutrality while challenging the legs evenly.

1. Seated Leg Curl – 3x10–12

Goal: Target left posterior hamstrings

Cue: Shift left knee back slightly, stay stacked

2. Hyperextension with Band Hold – 3x10

Goal: Even out hamstring recruitment and ribs

Cue: Left arm down, right band pull with abs on

3. Single-Leg Leg Press – 3x10–12 each side

Goal: Stabilize pelvis in unilateral movement

Cue: Left side = IR bias; Right side = ER control

4. Hat Squat – 3x8–10

Goal: Encourage bilateral loading

Cue: Slight left knee pullback, even SI pressure

5. Bulgarian Split Squat – 3x10 per side

Goal: Reinforce IR on left, ER on right

Cue: Left heel heavy; Right glute dominant

6. Offset Stiff-Leg Deadlift (Optional) – 3x8–10

Goal: Balance hamstring/glute activation

Cue: Small plate under left foot

7. Walking Lunges (Optional) – 2x12 steps

Goal: Smooth left IR transition

Cue: Left = slow and stable; Right = controlled drive

Pro Tips for Symmetry Gains Focus on Feel: Prioritize activation of the correct muscles over heavy loads. Don’t Chase Perfection: Minor asymmetries are fine—this routine targets dysfunctional extremes. Test & Retest: Use ROM assessments every few weeks to track your progress. Off-Gym Habits Matter: Don’t slouch or lean right when driving or standing—your gym work starts with awareness. Final Word

Whether you’re chasing a pro card or just want to train pain-free, addressing asymmetries like Left AIC and right lateralization is a game changer. Follow this program 1–2x a week alongside your regular split, and you’ll not only perform better—you’ll look better too.
