What type of training focuses on exercising one side of the body at a time?

The correct answer highlights a specific approach to strength and conditioning where exercises are performed on one side of the body at a time. This training method, known as isolateral or unilateral training, emphasizes balance, stabilization, and strength development of each side independently. This can lead to improved muscle symmetry and reduced risk of muscle imbalances, which are common when performing exercises bilaterally (using both sides simultaneously).

In this type of training, exercises such as single-arm rows, single-leg deadlifts, or single-arm presses allow for targeted strength development and can also enhance coordination and core stability. Unilateral training can be particularly beneficial for correcting weaknesses and improving performance in sports and everyday activities.

Other training methods mentioned do not focus on one side of the body at a time. Bilateral training involves simultaneous movements of both sides of the body, functional training emphasizes exercises that improve daily movements without the specific focus on unilateral strength, and circuit training consists of a series of exercises performed in succession with little rest, which can involve both unilateral and bilateral movements.
