Have you been measuring your RHR in the mornings? If so what was it before famine and what are you at now? How much weight have you lost since starting famine? If you are down roughly 1lb/day you're on track, and based on some of your other comments I'd say you are there and don't need to do workout 3. Finish your famine though.
1) I haven't taken creatine for some months, if I will take it together with the formula do I need the charge phase 20g per day also?
What brand/type of creatine are you using? Do you mean a loading phase? Others will weigh in, and this has been controversial in the past, but generally loading phases for creatine mono are considered a waste of powder/money. Just dose as normal. If it's PH balanced like found in
Kre-Alkalyn or
Kre-Anabolyn then definitely no loading is required.
2) When and how should I take the "Burn it up"?
Burn it Up is a perfect fit for cruise. Each to their own though. Sometimes I just use it when I need some extra jam in the morning. I like to take 1 or 2 a half hour before I go for a new 1RM. Helps me concentrate when I'm breaking PR's.
3) I know the calorie intake is not the same during the whole feast but I dont remember where I saw it, can somebody clear this for me?
I need some help on this one guys. I think for the first 2 weeks it's 120% maintenance on workout days and 100% on off days. After 2 weeks it's 100% on days, 80% off days. No less than 20% of your calories should come from "The Formula" on workout days.
For dumbbells vs barbells, my take on it is that with a barbell you can increase your total tonnage which is good for 1rm, alpha strength movements. Use the barbell for your loading patterns or static holds. Dumbbells are good for strength of the stabilizers. I use dumbbells allot for my EDTs (beta). Everyone's different, you'll find what works for you shortly.
Be careful with your back. I broke mine and moved my L5 vertebrae 1 cm. Check pg 35 of BP2.0 for a sweet hip belt and loading pin that will let you pile on the weight for squats without stressing your back.
Lastly, have you read through Rob's sticky?

The hard part is almost over. When you finish famine, the first thing you have to do (it's now mandatory) on your first day of feast, go find your favorite buffet. Your mission is to earn a lifetime ban from the fine establishment of your choice
