“We are doing the samba next week and so far, it’s really hard!” Amber wrote in her Parade blog. “It’s a lot of bouncing and it’s really quick and very energy driven, which I’m excited about because my cardio and my stamina have been getting a lot better. It’s going to be fun to push myself in this dance and see what I can do.”
