Yep it def helped mine! I do 4-5 classes a week - spinning, circuits, pilates and bums and tums. However just being more active within your lifestyle will make a huge difference. For example, if something needs to go upstairs - take it up, rather than leaving it until you are going up anyway - if you see what I mean. Go for a walk during your breaks at work, walk the school run or at least park further away from the school, park far from the supermarket door, spring clean the house, wash the car, etc etc.
