2. Swap your chair for a fitness ball 用減肥球代替你的椅子
You might feel silly but sitting on a fitness ball instead of a chair when you watch telly will help tone up your belly. You have to use your muscles, especially your stomach muscles to balance and stay on the ball.
也許你覺得這樣做有點(diǎn)傻,竟然坐在一個(gè)減肥球上而不是日常坐慣的椅子上來(lái)看電視;然而這非常有利于強(qiáng)健你的腹部,當(dāng)你不得不用你的肌肉,尤其是您的肚子上的肌肉來(lái)平衡坐在球上的身體時(shí)。
