Ok, this will be easy for you.
Basically for your nutrition you need to stick to about 12-14 calories per lb of BW, a relatively high( 1-1.5 G per lb BW) protien intake(no more than 1/2 from skaes) and keep the carbs roughly the same but make sure they come from sources like Quinoa and ezekial. lots of veggies are essential. th rest of your calories need to come from healthy fat sources(fish oils, mac nuts, avocados, etc.)
Your training should stay pretty basic right now with your goal being to add muscle to your weak points.
Your weak bodyparts need to be trained 2x weekly
1 day should be low rep(6-10 reps per WORK set) and moderate set volume(9-12 work sets for large bodyparts, 6-8 for smaller ones), the other day needs to be lighter(10-20 reps), with a lower total set volume(8-10 fr large bodyparts, 4-6 for smaller ones). Rep cadence should be about 1 second up, 2 seconds down and rest periods are no more than 2 minutes on heavy days, no more than 1 min on light days
Your strong points an be trained only 1 time a week utilizing half the exercises being heavy/low rep and the other half being high rep /low set volume. rest periods here are roughly 1.5 min(obviously)
Hope this helps! keep me updated and when you are ready we will take your stats and create for you a dynamite pre-contest program
