Vanessa Hudgens has been hitting the gym. The results are obvious.

The former "High School Musical" star went into hardcore training for her bad girls action flick, "Sucker Punch," and she shows the results to Shape Magazine. They're impressive -- especially the six pack abs -- but they came with hard work. She now lifts weights, does pilates, practices yoga and spins. Thanks to her friends and cast mates.

"I wouldn't have been able to do it if it weren't for the other girls [co-stars Abbie Cornish, Emily Browning, Jena Malone and Jamie Chung]. It's because of them that I got so strong," Hudgens told the magazine. "In the beginning, I could dead lift 135 pounds. By the end, I lifted 180. I was a monster!"

She's also had to summon a different kind of strength: the emotional kind. Having broken up with longtime boyfriend Zac Efron, she looks back fondly on their five years together.

"We grew up together," Hudgens said. "It was nice to have someone to share all of those experiences with."

Unfortunately, the experiences were become fewer and farther between.

"Long-distance relationships are hard no matter what," says Hudgens. "When you don't have face-to-face time, it's just different. Having an iPhone helped, but it just wasn't the same."
