l run to keep in shape for swimming (30 min a day) & today l ran for 10 minutes & then decided to try the elliptical machine. l used it for about 20 minutes & overall l was less tired than if l had run for 30 minutes like l usually do. my heartrate was about the same but my calorie burn count was twice as much as when l ran!

i tend to think running would be a better workout because its harder for me personally but is that a myth just in my head? l was talking to one of my friends who majors in personal training/fitness in college & she said it was probably due to the impact that running gives you that makes me feel that way.

do you guys know which is a better workout? should l try the elliptical machine more now or would running still keep me in better shape for swimming? & other swimmers - what machines do you use/what other training tips do you do that keep you in shape for the swim season? thanks!!

Ellipticals are always easier on your joints, so l would recommend that, even if it means having to go for a bit longer to get the same workout.

i'm a competitive swimmer too! high five :) ok so anyways, l usually swim 6 times a week, so its pretty hard on my joints, so l like using the elliptical machine. l think 10 minutes on a running machine is good, cuz it trains your breathing mostly, and is good if ur training for short distances.

l pick whichever machine is open. ;-)

If you are trying to maintain your aerobic fitness, then select whichever machine that will keep you motivated. That might mean that you alternate between the two. And to maintain base aerobic fitness, it is best to go longer -- try for closer to 60 minutes if you can.

And do not believe the calorie count given by those machines. They are notoriously inaccurate.
