Hello,
I own Tony Little's Gazelle, the very basic one with nothing to make it glide harder or easier.
Anyway, people have been telling me that this machine is not sufficient enough for fat loss.
So anyway, I tested it out with my heart rate monitor and did a 30 minute cardio workout on it and I easily met 150 beats per minute and I could have easily have gone higher. That is well above my elevated heart rate for fat burning, so in my opinion, it is sufficient enough for fat loss as it has proven to elevate the heart to the proper zone. professionals say all we need to do for proper cardio is elevate our heart rate fast enough to meet our personal fat burning zone, and this machine past the test. To tell you the truth, I think almost anything that helps us move fast will do the trick. A lot of people believe it has to be a machine where you can make it really hard to move and so on, but if that is what they want, there not trying to burn fat, they are wanting to tone and build muscle or work on endurance, not fat loss. We just need to elevate our heart for proper fat loss.
Any opinions regarding this machine and other comments are welcome. Thank you.

The only way to know for sure is to test it out. It sounds like it might work, although when you gain more endurance, it might be harder to keep a high heart rate. Only time will tell really. Keep working hard and let us know your results.
