You can't not exercise and expect to lose weight. Everything counts, if something seems to small to me like walking home for 5 minutes I always think 'hey your still burning calories' it helps when I feel like crap LOL
Anyway every second day is gym day. 30 mins -1 hour cardio work (bike, treadmill, rowing machine and sometimes cross trainer) then an hour of circuit weight training. After that if I don't feel like enough is done it's back to the cardio room.
On no gym days it's my aerobics dvd that goes 40 mins - 1 hour. It's called ultimate challenge ultimate results, works everything. Cardio, hand weights, abs, squats, stretching, push ups, everything lol. I often feel more out of that than the gym!
On lazy days or when I want to do more it's off for a run along the beach or a power walk.
It's really working I've lost 4 kg in the past month
