I've previously owned a Wii and had Wii Fit...whilst it was fun, I didn't think it pushed me hard enough. Also I found that sometimes it wouldn't track movements well. I also played Just Dance on the Wii, and again I found it wasn't good at tracking your movement...I would actually work hard and try and follow the routines, often with the console not picking it up but my DH would often just wave the remote around and it would say 'Perfect! Great work!' etc. I found it was more fun than a workout that had me sweating.
We now have Xbox Kinect, and its fantastic. My favourite game is Your Shape Fitness Evolved 2012. Its great, really gets you sweating, and is very precise at tracking your movements etc. And you don't need to hold a remote! Also have Zumba Fitness which again is fun and gets me sweating. xxx
