In my Cardio on Elliptical Trainers I mentioned that I had joined a gym to get more variety in my cardio workouts. The way that is has turned out I am now doing my cardio exclusively on the elliptical trainers in the gym. My waterrower is now only used for a quick warm-up before my weight training sessions in my home gym. This has come about for three reasons.

1. The motion of exercising on the ellipticals seems to be a lot more gentle on my knees than rowing.

2. On the elliptical you can control your work rate by setting the resistance or pedalling faster. On the rowing machine it's a case of pulling harder or pulling faster. Somehow on the elliptical it seems to be easier to get my heart rate up to the target zone and to keep it there.

3. Doing cardio for 30 minutes at a stretch is pretty boring. In the gym there is more going on to distract you, so the time seems to pass a bit more easily.
