Best Bodybuilding Routine: Strength & Volume Training
Volume training is done with lighter weights, which lets you lift more reps (for example: 3 sets of 12 reps). Which puts more time under tension on your muscles and gets lots of nutrient rich blood pumping through them. You will get a great muscle pump with this style of training, which feels great.
The pump really means absolutely nothing for gaining muscle.
Time under tensions is important, but so is overall tension, which is reduced with high rep sets. You could say that the stimulus is
TUT x OT = stimulus...in arbitrary units.
Also, most increases in size will occur via sarcoplasmic hypertrophy, and will only occur to a certain point whereby to maintain fiber functionality (and keep gains going) you will need to focus on myofibril hypertrophy, which is accomplished with higher tensions (4 x 3-6 reps).
