This first challenge is a good place to start. It's all about body locomotion.
Try to do a walk and a run. For extra challenge do a walk to run then back to walk.
Like all weekly challenges, topics are introduced every Wednesday and are over the following Wednesday when a new topic is introduced.
For posting work that all can see, Vimeo is a great way to do that. Join
