Query: Great, but could be more intense :-)

Jen is a favourite instructor of mine. Her routines are fun and energetic and this is the same. It's an intermediate workout with basic choreography and lowish impact. It does get your heart rate up a bit and you do sweat a little, but it isn't quite challenging enough for me.It's a combination of classic aerobics and fun latin moves. You learn a basic aerobic move, and then she adds the latin flare to it. I personally have only done this twice but never felt sore or tired as a result of it. I'd use this on a day where I can't be bothered doing much else but still want to do something. It's certainly going to burn off some calories, but advanced exercisers won't be overly impressed with this. Jennifer is motivating and personable like usual, but I hope her next workout will be a little harder and more challenging.
