Bodybuilding not like personal training, is a workout specifically with weights and fitness machines. It’s aim is the quality muscle mass gaining, proportionality, symmetry and the definitive form.
We train specifically for each muscle group too, we isolate it from the others. The training is made up from basic and isolation exercises. It’s specific is to increase the performance and using even heavier weights.
We place an even greater connection between exercise and nutrition. Rest days will also be more decisive because of the development.
Beside that i suggest natural food supplements which help the muscle gaining.
