Why train one side at a time?
Unilateral exercises are those that predominantly work one limb, such as single-leg squats, step-ups, and lunges. Exercises like these will improve strength, stability, and coordination by isolating the limb(s) of one side of the body. Incorporating unilateral training can improve balance, agility, and movement symmetry in sports and everyday life.
Neuromuscular Benefits
The benefits of challenging on one side or limb of the body include:
Improved motor unit recruitment (using more of the fibers in an individual muscle) on the working side, improving coordination and control of the body outside of its usual two-sided patterns.
Improving balance by engaging the stabilizing muscles in the hip, knee and ankle more than when both feet are on the ground.
Improved proprioception (joint position awarenesswithout visual feedback), which can improve bodily awareness and reduce the likely.
Cross Education effects
Neural adaptations from training one limb can also enhance the strength in the untrained limb by activating parts of the brain that improve strength and coordination on the opposite side. This is why we often spend some sets training the uninjured limb during rehab: the stimulation that occurs in the opposite side of the body and brain can "cross over" affect both limbs.
Load Distribution and Muscle Activation
Along with the increased muscle activation, unilateral training also changes the load across the spine. Challenging one side and not the other increases the demand on pelvic and spinal control because the athlete now has to resist some element of rotational, forward/backward, or side-to-side force. Single-arm and single-leg movements are thus a key part of our rehab approach to lower back and neck problems.
Unilateral training offers a wide range of benefits: improved coordination, strength, and neuromuscular control on both sides of the body. Whether you're recovering from injury or looking to improve overall performance, unilateral exercises are a key tool for building a more balanced, resilient body.
