Your ultimate BF goal should not be what your short-term goals are.
When I work with my clients, the type of goals we set are:
- I will go to the gym a minimum of 4 times a week, and aim for 5 times a week;
- I will allow myself to cheat on the diet no more than 4 meals out of a week;
- I will keep a log of my workout and dieting plans.
These action-based goals work a whole lot better than a blanket statement of, “I want to be 15% bf” because it is something you can check off and say you have done within the time limit you are given.
I definitely agree with reading up on diet. Check out Berardi’s precision nutrition system. It’s more expensive than the book alone, but it is worth it.
I’d recommend getting a trainer if you can afford it - someone to be accountable to and to keep you motivated. Even if you only see them once a month.
Also, the health of your skin has nothing to do with how saggy it will be after you lose a ton of weight. Please listen to me on this one - I have had a lot of clients say, “I lost 35 lbs quickly, but what can I do about my triceps? The skin makes me look fat!” After all that success, they feel discouraged.
Sadly, there isn’t anything I can do. I can try to get them stronger to fill in the skin a little, but it takes awhile for skin to adjust. At your age, you’re beginning to lose elasticity in the skin. This is a fact of life, nothing to do with genetics. Slower (not slow, but balanced) progress will make you look thinner in the long run because your skin will shrink with you.
This is not to say that I don’t think you should keep your goals and enter the competition. Everyone’s first competition is quite a learning experience. Going there slightly out of shape and expecting not to do well will free you from a lot of the stress of the “first time” and give you a ton of experience you need for the next comp. There’s nothing better than to get used to the process with a practice run before all the performance stress kicks in.
