Bilateral movements, which use both sides of your body, give your dominant side a chance to compensate, but with single-sided exercises, “you can’t hide or mask that,” said Vikash Sharma, the owner of Perfect Stride Physical Therapy in New York City. For that reason, performing unilateral movements can help you spot muscle imbalances or limitations in your strength and mobility. These exercises can also help improve your balance, coordination and core strength, Ms. Middlekauff said.
