How can I get stronger legs without getting too bulky?

Having strong lower extremities is advantageous for baseball and softball players. Almost all the strength and power to hit farther or throw faster begins in the legs. It is important to remember that getting stronger does not have to mean getting bigger as well. Understanding the acute variables that allow for strength adaptation versus those that optimize hypertrophy (muscle size increase) will help guide your workout program. When performing a strength exercise, perform 8-12 repetitions for 3-5 sets using a moderate weight (about 75-85% of your 1 repetition maximum). The weight you choose should make the exercise difficult to finish on the last repetition.
