i will offer a few opinions.

1. I think a personal trainer would definately be a big help to you. Make a list of exercises that you want to do on the CKD plan. Then if you currently cant do them ask the trainer to help you find and alternate exercise that would work the same muscle group. I suppose you could do this by posting messages here but a trainer will be able to help you much more, especially if you are a novice lifter.

2. Fruit juice usually contains fructose and fron everything i hae read fructose should be avoided. I spent about 15 minutes going through the cooler at my gym until i found a suitable post-workout carb load beverage. I do all my workouts on an empty stomach.

3. I cant be much help on the supplements except that Glutamine is recommended pre and post workout

good luck
