Karrueche Tran's diminutive frame means she finds it easy to stay in shape.

The 28-year-old beauty, who is best known as the ex-girlfriend of singer Chris Brown, says simplicity has always been the key to her workout plan and her 5ft 1in-build helps her to stay in good condition.

She said: ''Because I'm so small I don't need to work out super hard, I don't want to be a muscle on a stick. I really work on my abs and I'll do crunches and I work on my butt. I do tonnes of squats, jump squats and fire hydrants.''

Karrueche explained that she tends to workout at a relatively sedate pace and only does so around three times per week.

She told IBTimesUK: ''I try to work out as much as possible. I'd say on average, like, three times a week. I have a small frame so I don't do any intense workouts.''

Karrueche combines her workout regime with a healthy diet, which includes drinking ''tonnes of water'' and staying away from fastfood.

She shared: ''It's so hard because it's so easy and convenient. I choose healthier choices when I'm eating. It's not easy, it's hard to eat healthy.''
