In strength training, what does variable resistance aim to achieve?

Variable resistance in strength training is designed to adapt the load applied to the muscles throughout the range of motion of an exercise. This concept allows individuals to experience different levels of resistance depending on their strength at various points during the lifting movement.

When lifting weights, certain muscle groups may be stronger at specific angles or positions in an exercise; variable resistance training adjusts the resistance to match these strength levels, helping to maximize muscle engagement throughout the entire motion. This adaptability is particularly useful because it can lead to improved strength gains and muscle development while reducing the risk of injury.

Options such as constant muscle activation, standardized weight lifting, and selective muscle targeting do not capture the primary function and benefit of variable resistance training, emphasizing why adaptability to different muscle strengths stands out as the correct choice.
