Chris Daughtry pics prove that hard work pays off

American Idol alum Chris Daughtry has posted an inspiring picture on Twitter to reveal himself after a 23 pound weight loss and body transformation thanks to a strict diet and dedicated workouts.

Two comparison pictures are circulating on Twitter. One compares Chris to himself in 2010 when he was “significantly heavier.” To reveal the results of his 90-Day Challenge workouts, another shows the difference just three months of hard work can do.

In September of last year, Daughtry shared his inspiration to lose weight and his personal diet tips with People Magazine. "When I've gone on tour in the past, everything has gone out the window," he tells PEOPLE. "Late-night eating, junk food, pizza, donuts, beer. I gained 25 lbs. and I didn't realize it until I saw photos myself and I went, 'Oh my gosh, I can't even see my jawline. Who is that guy?' "

His four “on the road” diet tips include:

No late night eating: "I've got to be very smart about what I'm taking into my body and when I do it," he says. "So I have to stop eating late at night, which is hard. When you're on tour, you're up late, and it's tempting to eat, so I have to avoid it."

Stay away from compromising situations: "I love pizza. If it's around, I'm gonna eat it," the singer explains. "If there's a cheeseburger around, I'm going to eat it. If there are cookies, I'll eat a lot of them. So one key is not to have them around."

If you overeat, pay for it immediately: "If I do eat those things, which is going to happen, I pay for my carnivorous sins right away," he says. "I get more exercise and burn off the calories. You have to pay for them as you go, and not let them turn into 25 extra pounds. I'm not going to totally deprive myself of the things I love to eat; instead I'll eat them in moderation and then immediately deal with the fallout."

Get exercise every day: "When I'm on tour, I get exercise on stage," Daughtry says, "but on off days, I have to do circuit training or cardio. It takes a lot of work, but nothing about staying in shape is easy."

However, he says, he not only wanted to lose the excess weight, but also desired to be in better shape. He and trainer Jen Hendershott completed the Body by Vi 90 Day Challenge. “Big THANKS to @jenhendershott for being an incredible leader and helping me achieve my fitness goal," Chris writes. "You're awesome:)"

He works out in his large home gym in North Carolina “almost every day.” He also takes portable equipment such as resistance bands with him when he is away from home on tour. Chris’ challenge videos can be viewed at chrisdaughtrychallenge.com/watch.
