If you're fit, jumping jacks won't give you much of a cardio workout.

Rowing.

It's fine, but it has the same problem as the elliptical trainer where the legs end up taking all of the load. Rowing is perfectly balanced, if the technique is good.

Rowers have the highest absolute VO2max of any athletes.
