There is no denying Halle Berry's beauty. She was a Bond Girl for heaven's sake! She shares a few basic tips for how she stays fit, including a basic pilates move, for which I attached a video :) 1. Uphill walking is the best cardio exercise. (Do it outside or on a treadmill's highest incline.) It's easy on your knees while tightening your butt, thighs, and lower legs. 2. Dumbbells are better for muscle toning than weight machines, because they require no adjusting, they allow the body to move naturally, and they can be used for dozens of different exercises (while machines have a limited repertoire). 3. MUST-DO MOVE: Upper-body twist TARGETS: Obliques (sides of stomach) HOW TO DO IT: Sit on a mat or rug with your knees bent and your feet flexed. Lean back slightly (at a 45-degree angle). Now reach across your body with your right hand, as though you're grabbing something on your left, then reach to the right with your left hand. Do 10 reps (five on each side), rest for 30 seconds, then do two more sets.
