Week 2 is done/Week 3 begins!

So, I have finished week 2 and I have some questions that I don’t know how to answer.  In my last set as compared to my first set, my rep count decreased in the 30 seconds I allotted myself, and I wonder if I should continue doing this round of exercises until I become stronger?  Or should I go to the next round and see where that takes me?  I am going to move to the next round of exercises for now and see how I progress.  If I feel like I am moving too quickly, I will continue with the same round for another week.

Also, because my rep count is decreasing and I had to downsize to the 10lb weights vs the 15lb weights which I began the week with, does this mean that I am starting too strong or is this a normal progression?

Since I have no one to discuss these questions with, I will just keep them in mind as I continue my 16-week to perfect abs journey.

On a better note, I am extremely excited for Week 3 exercises!  Below is the routine that I begin tomorrow for this week:

1A: Elevated pushups/ 1B: Plie jump w/ medicine ball

2A: Negative chin-ups/ 2B: Forward Lunges

3A: Arnold Press (15lbs)/ 3B: Step up w/ weight (10lbs each hand)

4A: Band Row/ 4B: Hamstring Curl

5A: Toe Touch w/ weight (10lbs)/ 5B: Side plank

Sprint 20 seconds / Rest 40 seconds
