Now that she’s engaged to basketball player Kris Humphries, Kim Kardashian is definitely kicking her workouts up a notch before her August wedding . According to Us Weekly , she’s refining her shape with the help of celebrity fitness trainers Gunnar Peterson and Tracy Anderson. To shape her arms and upper back, Kim is doing free-arm exercises, “where I’m changing the movements all the time.” Instead of doing repetitive movements in a straight line as in a triceps kickback or a shoulder press, you continuously vary the angle and direction of your movements, making them more creative. For example, instead of doing a basic bicep curl where you draw the hand weight or resistance band toward your shoulder, you pivot from your elbow and slowly move your hand in different ways (like you’re drawing in the air), which

not only targets the biceps but also tones the forearms, triceps, and shoulders. This reminds me a lot of Shiva Rea’s approach to core work . Rather than doing basic crunches, she has you explore lifting and swaying your torso and legs in creative, dance-like ways. It may seem a little weird to have such free and seemingly unintentional movements, but they’re actually really effective. It keeps your muscles guessing, and the varying movements end up targeting every part of your muscle. This technique can be used with just about any dumbbell or resistance band exercise. I recommend using a lighter weight or tension as it doesn’t take much to feel this type of movement working, and you don’t want to risk injuring yourself.
