I'm only on day 3, but I feel the same way. I felt like the work out was just a tad easier today. Less pauses and less gasping for air, ha ha. Today I totally blasted through most of the exercises, and I didn't seem to sweat as much and be as red as was the first day. I still have problems with the butt kicks and jump ropes as well. I'm going to try and do each level for 10 days like some suggest, but we will see how I fare when I get to level 2. Its crazy though, I actually look forward to coming home and working out! And I was super surprised that I actually did it today considering I was up at the gym at 5:30 this morning.

Go Us!! I can't wait to see what we all look like at the end!!

Keep it up!

Well I'm on day 6 tonight. Was supposed to be last night but I had my eyes dilated at the eye dr and apparently I am one out of one million that had a severe allergic reaction and got really, really sick. I'm much better today and ready to pick up where I left off. Push ups are so hard on me too, even the girlie ones I have to stop and plank it out for a few moments before I drop again. My arms are really sore as well and I think I'm going to use my 1lb weights for those arm raises/side lunges towards the end, the 3lb weights are murder and I'm afraid I'm pushing too far too soon.
SO day 6 tonight! Excited!

My husband tried to convince me to get the 5lb weights and I'm so very glad I didn't listen! The 3lb weights are so difficult and It's going to take possibly the whole 10 days just to get through the whole video using them. I was thinking that maybe I might hold onto one 3lb weight with both arms for the arm raises so that way it's still heavier then my 1 lb. weights but it won't kill me. I was also looking at my food diary here on MFP and I barely eat any protein at all so I bet that's why my arms and muscles are so weak and sore. I'm thinking about maybe getting a protein shake to take in the morning or after my work out... I don't know, still up in the air on it. Hoping to get in day 6 tonight but I promised my girls we would paint nails and its my night for dinner so busy me! But I'm sure I will find that short window of time to get in there and let Jillian have her way with my poor body hahaha....

I just finished day 5 today and feel I'm pretty much in the same spot you were on day 5. Definitely noticed most everything other then the cardio is getting better. lol
I'm bouncing around between 3lb for anything shoulder and 5lbs everything else.
I think I might need to get a set of 8lbs though because the 5lbs are like lifting nothing for the chest fly. I'm a weirdo. lol

Day 5 and it's getting easier. It's the first set of cardio that's killing me. Jumping jacks just make me so out of breath. I am still catching up from those in the warm up. It doesn't help the first set of strength exercises also cause me to be out of breath. Having said that it is getting easier.
The lunges are still hurting but getting better and also the anterior rasies are getting there. I can almost do them all with the weights! The only other things I need to work on are the push ups. I can do them, so I just now need to push myself.
