It's easiest to do nothing at all.
If you learn how to take care of your joints and how to exercise with good
technique, you can use any of these machines safely and with good results.
If you learn how to strength train as a separate item from aerobic training,
you will likely benefit in many ways. I see so many people with big bellies
spending an hour a day on a treadmill, bicycle, or elliptical trainer - such
training does not seem to help them.
Obviously "people with big bellies" could stand to lose some weight,
but to say that an hour's worth of cardiovascular work a day is not
helping them seems a little negative.
