How do you execute this type of training into your program?
First, you should be strength training already—doing squats, deadlifts, shoulder presses and chin-ups or pull-ups. These types of exercises increase your force production and will improve your ability to perform explosive exercises.
The best way to integrate explosive training into your program is by doing a four-to-six-week block before your next big race. After you complete the training block and the race is over, immediately start strength training again. It is imperative that you maintain your strength over the long season to stay healthy and injury free.
