Viaxyl Muscle : In order to design a good weight training program it's imperative to perceive the nitty-gritty of weight lifting. Stressing the muscles, resting, then increasing the stress level placed on the muscles and therefore the repetition of this process (progressive overload) is the fundamental philosophy behind weight training designed for building muscles. The beauty of solely coaching with weights every few days is that the times in between full-body workouts can be used to add some cardio sessions instead of looking forward to ineffective cardio added on at the tip of a workout.
