What is the easiest way to get Muscles?!

Muscle growth requires consistent muscle damage, protein with which to fix damaged muscle and glycogen to fuel the repair.

Eating a healthy diet full of carbohydrate (for glycogen) and protein (for repair) combined with regular strength training to work all muscle groups equally (to damage the fibers and require them to grow back larger). Remember to take into account the need for muscles to recover for at least a day between workouts.

Various magazines can give you pointers on the best combination of strength training to provide maximum results.

if you already have low body-fat then you can focus solely on increasing muscle volume remembering to consume your muscle requirements on top of your daily activity requirements.

Stick to real protein (not shakes) and don't go crazy as it can tax your kidneys if you consume too much. There are scientific sources online that will provide you with the exact amount of protein you require, if you're an America you're probably there already.

Genius and muscly gym regular.
