Tap into the secret weapon responsible for the world's most coveted and sculpted bodies - from Hollywood A-leisters to pro athletes - and let fitness guru Gunnar Peterson map out your optimal get-in-shape strategy. In his groundbreaking book, "G-Force", Peterson - whose clients include Angelina Jolie, Jennifer Lopez, Penelope Cruz, Pete Sampras, Lucy Liu, Ben Affleck, Sylvester Stallone, Matthew McConaughey and more - reveals sure-fire techniques to help you achieve the rock-hard body you've always wanted. His proven exercise system will not only get you into the best shape of your life, it will encourage you to stay in shape by doing something truly remarkable - keeping work-outs fun, upbeat, and interesting! After years as "the fat kid" relegated to shopping in the husky section, Peterson got serious about fitness as a student at Duke University, where he concentrated in physical fitness and psychology. Once whetted, his appetite for learning about fitness and exercise became insatiable - and soon so did his desire to share his newfound knowledge with those struggling to get in shape. Through his 16-plus years as a personal trainer, Peterson began to recognize the four crucial ingredients of any fitness success story: consistency, motivation, information, and variety. Now, for the first time in book form, he charts the life-changing fitness formulas that have made him a favourite of the stars.
