Ok, as some of you might have seen before I do run alot and my waistline has gone down (that makes me happy)...

BUT... (insert alot of foul language here)....

Over the last two months I have started doing the aerobics with the girls in the park (yes, some of them are good looking:-)

I sweat alot, eat the same or less than before- but I have still managed to gain 6kg... YET, the stomach and my man boobs are going down??? what is happening? What am I doing wrong???

Actually, it's not unusual to gain weight with exercise. Muscle has a greater density than body fat so you can quite often get physically smaller in the stomach area etc but be heavier.

But still, 6 kgs in about 2 months??? Is that not too much???

Yes, gaining 6kg of muscle in 2 months is unlikely. Especially without weight training, with aerobics only.

Maybe your weighing scale is broken and you're actually losing weight.

Gaining so much weight but losing mass is confusing when muscle gain can probably be ruled out.
