Fitness Equipment!

I agree on the elliptical because it's so versatile and there's almost no chance of an injury to your joints (vs. treadmill) since it's virtually impact-free. Smooth as buttah! You'll be more inclined to stick with it if you don't get injured and it's tailor made for fat burning. If you incorporate interval training with steady-state cardio, you'll see that weight drip right off. Always do a warm-up/cool-down but do a steady pace for a longer period (e.g., 30-50 min) one day, then do intervals the next day, like the equivalent of a sprint (70-85% HR) for 1 min, followed by 2 min of normal pace (i.e., ~50-65% HR) for 20-30 min. Intervals are for no more than 3x/week because they're so challenging to the body and you need recovery time. Besides really working your heart with the arm movements, you can get a better workout by occasionally going backwards on it, too. Your thighs, glutes, calves, hamstrings, and abs will burn right into shape. There's many variations of those workouts so you'll keep your body guessing, too. Your gym should have good machines that keep your posture straight so you're not leaning forward or backward during your workout (very important) and the foot rest pedals are close together.
