Claudia needs to incorporate more plyometric exercises in her workout routine. What is one exercise she should add to MOST effectively increase her plyometric training?

Plyometric exercises use quick, explosive movements that stretch and then rapidly contract the muscles. Box jumps train this power by having Claudia jump explosively onto a box. Crunches and single-leg squats are strength exercises, while sprints can develop speed but are less directly suited to plyometric training.
