A woman in Grand Rapids, Michigan got a different kind of workout in a Planet Fitness the other day when she flew into a fit of rage and wrecked the place up.

Cellphone video shows the 20-year-old ripping various items off the front desk, including the credit card machine and a computer monitor. She also throws some punches at the man behind the counter while yelling, “I’ll come back, and I’ll kill you!”

She was charged with malicious destruction of property.
