Zero.
These gurus can only make changes in heavily juiced physiques. They just change up a few things and make someone "think", they are really doing wonders. It's all diet and genetics.
Exactly!
I see so many avg Joe and Jane blow buy into this extensive, overly specific and detailed diet and execise regime complete with a trainer and it makes me shake my head. Why is it considered near impossible to simply workout, eat a good diet and get a good physique. Now we have a cottage industries of self procralimed gurus on everything from diet to useing those retarded big rubber swiss balls for "core training".
I cringe when I hear some state level bodybuilder brag about their contest prep guru "brought them in on the money".
Arnold had some guys look at him before a show and keep him honest but he never seemed to need a diet guru, drug guru and special voo doo contest peaking regime.
I have been in/around bodybuilding and gyms for over 30 years now. I have judged countless contests in the NPC and before that AAU. I been in more gyms than I can count and seen thousnads of bodybuilders and fitness fanatics.
I have seen every kind of muscle building, fat burning pill and potion come and go.
In the end I have seen only 3 tried and true proven things that make any real difference in how your body looks:
1. Lose wt and sevreal pouns of body fat with sound , sensible diet and exercise.
2. A steady increase in muscle size useing good nutrition combined with hard, basic workouts with the wts.
*3. If you do 1,2 , adding some proven roids in a sensible cycle will increase what you get naturally.
Why do so many spend big bucks on gurus and oddball supplements , instead of maxing out on the basic stuff that is the reason for 90% of your progress?
?
Don't waste your valuble money and resources on gimmicks and gurus. Go to the gym , do a basic, bust ass routine of quality lifting , eat good and do some cardio...end of story.
