WATCH: Ronda Rousey's Intense New Bag Drill

UFC champ Ronda Rousey shows mad punching skills with this video of her brutalizing the heavy bag.

Ronda Rousey is arguably the most dominant female athlete in the world right now. The UFC Women's Bantamweight champion and with numerous other titles to her name, Rousey is undefeated, securing her last fight this past February in 14 seconds, the fastest finish in UFC history.

Right now, in addition to pursuing an acting career and showing assumptive reporters how its done, she's looking ahead to face Bethe Correia in August.

Rousey recently shared a "new bag drill" on Instagram and challenged coaches and trainers to guess its purpose. She performs the drill with freakish intensity, but you can bet that this is just a warm-up for whatever's next.
