The 3-part active dynamic warmup you'll see here is a great way to start any practice or pre-competition routine. It warms the body, reduces injury risk and improves performance.
Taught by Joseph Virga of Parisi Speed School of San Diego, this warmup has 3 phases: stationary, movement and then ground exercises, which activate muscles that are often neglected.
Demonstrating the moves are Serena Mueller, a freshman middle blocker at the University of New Hampshire, and Gavin Graff, an eighth-grader at Muirlands Middle School in San Diego.
