Completed w3r2 yesterday and my 7 year old daughter was desperate to come along. I was sceptical, however it sort of went like this...
Daddy, come on!
Daddy, why are we walking, shouldn't we be running?
Look Daddy, I can run backwards as fast as you can run forwards
Daddy, can you fix Spotify for me?
Daddy, what's for dinner (whilst skipping round me)?
Daddy, why is your face very red?
I was so distracted I hadn't realised I'd finished and actually ran the 5 minutes warm down in error!!!!
Oh, and for the stretches at the end she can literally bend double, and still talk all the way through it all. Morale of the story. Take a 7 year old with you. Total motivator!!
