Which of the following is NOT a benefit of flexibility training?

Flexibility training primarily focuses on improving the range of motion of joints and muscles, which directly contributes to enhanced flexibility. While it offers numerous advantages, such as increasing circulation and relieving stress, improving strength is not a direct benefit of flexibility training.

Flexibility exercises, such as stretching, primarily target the muscles' elasticity and the tendons rather than significantly enhancing muscle strength. Strength training typically involves resistance exercises that engage the muscles more intensely to increase their overall power and size. Therefore, while some forms of stretching might indirectly help with muscle recovery and can complement a strength training program, flexibility training itself does not inherently improve strength as its primary goal.
