Looking lean! Emma Watson shows off her toned midriff in stomach-baring crop top as she hits the gym

As Hermione Granger in Harry Potter,  rarely has an occasion to show off her figure.
But, clearly proud of her toned physique, the 21-year-old actress decided to wear a pink sports bra and very low-slung leggings to display her toned midriff as she hit the gym.
Emma teamed her exercise clothes with a grey jumper tied around her waist and a headband to keep her hair out of her eyes.

Since she is clearly in great physical shape, she can now devote her attentions to more spiritual matters.
She was clutching a book said to ‘offer a potent possibility to transform your life’.
The U.S. best-seller A 3rd Helping of Chicken Soup For The Soul features 101 ‘heart-warming stories to inspire and motivate you to love unconditionally; live more passionately and pursue your heart-felt dreams with more conviction’, according to the publishers.

However, talking about her figure recently, Emma said staying slim isn't something she constantly worries about - she is more concerned about staying healthy.
In a recent inerview, Emma said: 'It's just not something that I aspire to, to be super-skinny. It's not inspirational at all for me.
'I'm lucky that I'm this size naturally. I don't diet...I love chocolate and pasta and I love baking. I make a great raspberry amaretto cake!

'There is so much pressure on girls our age to be smart and pretty and funny and skinny - they have to be everything.

'I definitely know what that pressure is like, but my philosophy is to eat what you like and be healthy and exercise.'
