Kate Upton's Trainer Reveals Her Workouts Are 'Not for the Faint of Heart'!

Kate Upton makes her way through the airport with her pup on Wednesday (April 13) in Los Angeles.

The 23-year-old model’s personal trainer Ben Bruno recently gushed about her in People.

“Kate trains very hard,” Ben said. “Her workouts are not for the faint of heart! She really works at it, and she’s super motivated.”

“We have travel workouts that she can do with minimal equipment at a hotel gym, and body-weight workouts,” Ben continued. “When she travels, she’ll bring her Valslides and mini bands with her, and I have workouts to go with it.”

“She’s very disciplined with her diet,” Ben added about her diet. “She doesn’t crash diet, doesn’t do fasting or cleanses. It’s just very sensible, healthy eating. She really limits sugar, gets protein with every meal, and has cut down on alcohol. It’s healthy; it’s not a starvation diet. And she sticks to it.”
