"I think I try to promote self-growth and reflection for myself every day.”
Although she is an Academy Award winning actress with a rock star husband, Gwyneth insisted they are no different to any other family.
She said: "We have a scrimmage soccer game in our yard every day after school. It's so fun. Though Moses prefers soccer, Apple has been really loving gymnastics.
"I feel that mental happiness and physical happiness are so closely related, and especially for kids, because they have so much energy."
