Building up a lean body muscle is an integral part of our life. It requires you to have a regular exercising routine and a good gym schedule. You will have to do weight lifts and with time increase the weights or do more repetitions. You must try and set a new PR (personal record) on the lifts you do and gradually see the difference in your muscles.
To ensure building lean body muscle, you should always keep changing your PR. Increasing your PR makes you achieve a new target and have a lean body with all body tissues except the storage fat. You will have broad shoulders, toned muscles and chiseled abs.
