In my past 20 years of interaction with girls across the world I have found that girls live in fear and anxiety while growing up.

If we don't think that men and boys are part of the solution in this battle for gender equality for the balance between who we are as humans, we're undermining their minds and their spirits. They need to be part of the equation.

So, obviously, on International Women's Day, we are honoring the achievements of women, but gender equality and feminism cannot evolve in our humanity if we're not bringing our boys and men along.

Women's empowerment for me means knowing your rights, having the facts, knowing the truth about what is happening out there, here in our own country and the condition of women throughout the world.

For me, the way I go about training all of my clients is by using short bursts of interval training - it's the most effective for burning calories as well as for cardiovascular health and making you stronger.

If you're a coach and your team doesn't win, at some point you've got to change the coach.

I am sorry for causing anyone to lose faith in sport.

When I was younger, I avoided exercise or anything strenuous. I didn't even enjoy walking. As I got older, I spent so much time marking books or sitting at a desk writing that there was no room for exercise - not that I would have bothered anyway.
