London: Singer-actress Jessica Simpson is back in shape after she employed fitness trainer Danny Musico, who created an exercise regime just for her.

"It`s a 60-minute, interval-based workout. The best part is the punching, it gets a lot of aggression out!" quoted Simpson as saying.

Musico, who was a professional boxer, also trains Hollywood actor Leonardo DiCaprio, singer Justin Bieber and Simpson`s dad, Joe Simpson.

"She`s getting leaner and told me she went down three dress sizes. She`s pushing herself to new levels. She`ll run for three minutes as fast as she can, then rest for 30 seconds, then box for three minutes and so on," Musico said.

The 29-year-old actress, who is fronting her own show "The Price of Beauty", faced challenges in meeting Musico four times a week.

"With her clothing line getting ready for another season of `The Price of Beauty`, it`s hard to find the time. But when she`s at the gym, she always gives 100 percent," he added.
