Philadelphia police are on the hunt for a suspect who was seen on camera getting in a good stretch before robbing a Dunkin Donuts last weekend.

According to reports, the unidentified man wore all black with latex gloves and a ski mask and just before 7 a.m. when he entered the coffee chain restaurant, he was seen stretching out his hamstrings, and lower back.

Police say the suspect jumped over the counter and pointed a gun at the employee and demanded money. "You have 20 seconds to give me the money from the registers.” The assailant was then seen leaving the Dunkin Donuts and jogging through the parking lot.

Fitness experts say it's important to warm up your muscles before committing all crimes. (Sarcasm)
