1.Pick a plan and stick to it.
2.Take weekly pictures identical to the one's you have posted. This will allow you to post them here and get honest feedback from those who have been there done that and have no vested interest in your feelings.
3.I agree with tossing the scale, it matters not.
4.Do not reduce cals too much too quickly and do not increase cardio to the max from the beginning as you need to be able to adjust something when you hit walls.
5.This kind of goes with 1 but once you decide on a plan or a person to listen to try not to gather information that may contradict what you are doing. Doubting your prep can be as detrimental as out right not following it. You end up changing the plan and all things can go to hell in a handbasket.
6.If it were me I would steer clear of BSN and any other company that has a large amount of ingredients in their products. I am not saying they are inherently bad it's just in prep you want to have as FEW AS POSSIBLE VARIABLES influencing your condition. With 20+ ingredients per product it can be hard to nail down what is doing what to your condition. Stick to products with one or two ingredients and proteins that are very basic, ie not loaded with carbs and fat like Syntha 6(not normally a big deal but this is contest prep where little things can be the difference between 1st2nd or 4th 5th.)
7. With all the money your proposed stack would cost you could hire someone who has coached people in the past. Ask to see pictures of their results.
8.Have fun, good luck, your starting at a good condition IMO and your legs will give some guys a reason to take pause. I wish you luck!
Very nice list here!
