long answer:
It really all depends on how much you weigh and the type, intensity and duration of your exercise.
Ive attached a guide as to how much energy you burn per 10mins of exercise during different types of exercise.
A bottle of wine is around 500 Calories.
the calories/ 10mins /body weight during say traditional aerobics is:
Activity & Calories/10 min.
|
56kg
|
67.5kg |
|
90kg
|
Aerobics (traditional at high intensity)
|
95
|
115
|
134
|
153 |
So if your 79kg and work out for 40mins (1 hour minus warm up/cool down) you burn 540 Calories
so pretty much a bottle of wine
wine calories.htm (26.23 kb)
After looking at this stuff enough it makes sense why people throw around figures such as 'losinig weight is 70% what you eat, 30% exercise."
(you might have heard that your metabolism is boosted for hours after exercise, well unfortnately the current research does not support this popular opinon)

short answer:
one bottle of wine = one hour exercise session. more or less.
The fitness work does a whole lot more that just burn calories, so its worth keeping the fitness work up, but just really consider the impact of what you put in your mouth...
more stats:
If you get your diet working, and are able to consume less calories than you burn it is very possible to lose 0.5 a kilo per week if you get it right,
(if you are starting to lose weight after having put it on for a while)
3-4 exercise sessions a week will help you burn a whole extra days worth of resting metabolism on top
