The Key to Building Unstoppable Strength: Why Unilateral Training is the key

Uniateral Strength Development example
In strength training, the usual approach after mastering bodyweight exercises is to jump straight into bilateral movements like barbell squats and deadlifts. However, an often overlooked step in this progression is unilateral training, where you train one side of the body at a time. This crucial phase helps prevent muscle imbalances, improves coordination, and builds functional strength. And kettlebells—a tool that has been around for centuries—play a central role in effective unilateral training.
Why favouring Bilateral Training over Unilateral training initially is putting your progress at risk:
When you jump from bodyweight exercises directly into bilateral lifts like squats or deadlifts, one side of your body often compensates for the other. This creates compensation patterns, which can lead to overuse injuries, poor performance, and long-term muscle imbalances.
Research Insight: A 2014 study from the Journal of Biomechanics found that many athletes show weight shifts toward their dominant side during bilateral lifts, leading to muscle imbalances and an increased risk of injury. The study suggested incorporating unilateral exercises to fix these imbalances and improve performance.
Benefits of Unilateral Training Before Bilateral Lifts
1. Corrects Muscle Imbalances
Unilateral training ensures that each limb carries its own load, allowing you to identify and correct any imbalances. Movements like single-leg deadlifts or lunges force the weaker side of your body to work as hard as the stronger side, ensuring balanced muscle development.
2. Improves Coordination and Balance
Unilateral movements challenge your body’s stability. Exercises like single-leg squats or kettlebell swings require core activation and coordination, which not only improve your balance but also carry over into more efficient bilateral lifting.
3. Prevents Injury
By addressing muscle imbalances early on, you reduce the risk of injury when you progress to heavier bilateral lifts. Overuse injuries are common when one side of your body overcompensates for a weaker side, but unilateral exercises can help reduce this risk.
Research Insight: According to a 2016 study published in the International Journal of Sports Physical Therapy, unilateral training significantly decreases injury risks related to muscle imbalances, particularly in the knees and lower back.

Kettlebells ideal for unilateral training
Kettlebells: A Key Tool for Unilateral Training
Kettlebells, which have been used since the 18th century in Russia, are particularly useful for unilateral training. Exercises like kettlebell swings, cleans, and presses focus on one side of the body at a time, making them ideal for building balanced strength and stability. Unlike barbells, kettlebells allow for a greater range of motion, which enhances mobility and strengthens stabilizer muscles.
Core Engagement: Kettlebell movements, especially unilateral ones like Turkish get-ups or single-arm swings, activate your core muscles to stabilize your body. This enhanced core engagement helps build a stronger foundation for bilateral lifts.
Mobility and Flexibility: Kettlebell exercises improve flexibility, especially in the hips and shoulders, key areas for effective lifting. As noted in a 2013 study published in the Journal of Strength and Conditioning Research, kettlebell training improved hip mobility and unilateral strength in athletes .
Example Unilateral Exercises to Add After Bodyweight Training
Here are a few key unilateral exercises to include in your routine before moving on to heavy bilateral lifts:
• Lower Body: Bulgarian split squats, single-leg deadlifts (with or without kettlebells), step-ups.
• Upper Body: Single-arm kettlebell swings, Turkish get-ups, single-arm presses, and rows.
“ Balance Is the Foundation of Strength”
Skipping unilateral training and moving directly to barbell lifts can lead to muscle imbalances, poor coordination, and increased risk of injury. By incorporating unilateral movements into your routine—especially with kettlebells—you create a balanced, strong foundation. This prepares your body for the heavy lifting to come and minimizes the risk of injury.
Kettlebells, in particular, are invaluable in developing unilateral strength, core stability, and mobility, making them an essential tool in any well-rounded strength program.
So, before you pick up that barbell, remember that building unstoppable strength starts with balancing your body. Take the time to master unilateral exercises, and you’ll set yourself up for better performance and long-term gains.
