Lee Hayward's Total Fitness Bodybuilding suggests that it takes several months to start looking buff. The key to getting there is consistency with a workout and diet plan. Hitting the gym 3-4 days a week for a good workout is better than 5-6 days a week.
How Stuff Works explains that without adequate rest periods to allow the body to recover, progress can be hampered. As muscle starts to form, one must increase his weight resistance. An athlete should incorporate aerobic exercise into the weekly routine, and remember that no amount of work combats a poor diet. A nutritionist can set up a plan according to individual body types and personal goals; this helps individuals to reach target goals in optimal time.
