Whether you are looking to tone and sculpt your body, lose weight, gain a sporting edge, support bone strength, or improve posture, strength training can help you to achieve your goals. This book anatomises more than 100 exercises to identify the muscles worked and how they engage at each stage, so you can feel you're getting it right. Over half the exercises can be performed at home, and, where possible, at-home variations are given for those using gym machinery. Understand the hard science behind how best to build and maintain muscle mass, raise metabolism, and reduce body fat.
