The core of the matter...

...I'm so easily pleased..although some may not agree :) I walked into the gym today and squealed when I saw these huge fab posters suspended from the ceiling...
5 of them in a row and what they were telling us is coming to our gym.

I'm a huge fan of core training.  It's a good part of the reason I'm in the shape I'm in today. To build a strong core you need to exercise a variety of muscles from your hips to your shoulders. Full planks, side planks, press-ups, contracting your abdomen while Spinning and of course...'the' best... Kettlebells!  I'm looking forward to participating in the above

LesMills CX Worx '30 minute Revolutionary Core Training'. 

LesMills Bodypump is another fantastic class for an all over body work-out AND to burn fat. Not only do you get to tone your full body through resistance training with weights but for us ladies, this training helps to prevent Osteoporosis in later years.

Just have a read of what the experts say

Though cardio burns more calories than strength training during those 30 sweaty minutes, pumping iron slashes more overall. A study in The Journal of Strength and Conditioning Research found that women who completed an hour-long strength-training workout burned an average of 100 more calories in the 24 hours afterwards than they did when they hadn't lifted weights. At three sessions a week, that's 15,600 calories a year, or about four and a half pounds of fat—without having to move a muscle.

What's more, increasing that after burn is as easy as upping the weight on your bar. In a study in the journal Medicine & Science in Sports & Exercise, women burned nearly twice as many calories in the two hours after their workout when they lifted 85 percent of their max load for eight reps than when they did more reps (15) at a lower weight (45 percent of their max).

There's a longer-term benefit to all that lifting, too: Muscle accounts for about a third of the average woman's weight, so it has a profound effect on her metabolism, says Kenneth Walsh, director of Boston University School of Medicine's Whitaker Cardiovascular Institute. Specifically, that effect is to burn extra calories, because muscle, unlike fat, is metabolically active. In English: Muscle chews up calories even when you're not in the gym. Replace 10 pounds of fat with 10 pounds of lean muscle and you'll burn an additional 25 to 50 calories a day without even trying.
This is how I did it. What do you think?
