What kind of results? Weight loss? 'Toning?'
Weight loss is calories in, calories out. You have to eat less that what you burn (through exercise and day to day living). I can't see the Ab Glider burning a whole heap of calories, so you will probably have to supplement it with other exercise, like good quality strength training and some cardio.
'Toning' will only come once the extra fat is gone. You should ST before then so you have nice muscles to show off when the time comes. Also, muscle burns more calories than fat while at rest, so that is a nice side benefit of ST.
