Ok, so I absolutely love all the videos! Fromo, your T-rex arms are my fav.
Here's an older video of Zing's sit up, it was free shaped. My hands are close to her after giving the cue so that I can reward quickly, but they do not need to be there to get her into position. We are working on balance, she is a bit better now than this video but I think it's going to be a gradual thing for her. I'll post a new video tonight of both girls.
Sit up is at the 6 minute mark (this was a homework video for Trkman's puppy class)
