Sounds like my first week. Nope, you won't be like this. Day 1 is rough, and usually an easy warm-up/stretch before starting day 2 will help a lot (my first week, I started day 2 and the first round was rough, every other one was better). I usually find a wall or chair and do some standing push-ups, just to get my muscles use to the motion. With pull-ups, I hang from the bar (with feet on the ground) to stretch the arm muscles. Squats is just doing 1 or 2 every minute or so and some other leg stretches.
So.... long and short, it will be better starting next week and definitely by week 3. :D
