Big Brother's Josie Gibson is more of a little sister now! She's dropped 5 dress sizes and 3 stone using 30-Second Slim. Personal trainer James Stark created this Short Sharp Slim workout based on the latest science of High Intensity Interval Training. It's just 30 seconds of sweat, followed by an active rest. "Laboratory tests show it burns fat faster than any other form of exercise," says James. Plus, Josie reckons, "it's great if you're a bit lazy like me 'cos the hard bit only lasts 30 seconds at a time!" Three 20-minute workouts build in intensity from Level 1 to Level 3. In each there's… WARM-UP: 4 minutes of easy calorie-burning moves. MAIN WORKOUT: 12 minutes of fat-burning intervals & moves to tone up the bum, arms and belly. COOL DOWN: 4 minutes of stretches to lengthen the muscles. "Let's face it I was a real porker," says Josie. "But this did it for me--so go for it. All you've got to lose is your love handles!
