Just finished this one and my arms are still shaking, esp. my triceps. At around 42 mins, my whole upper body feels great. I like that the upper body bonus isn't put in at the end, she mixed each bonus exercise with the body part you are doing at the time. Some are at the end of the segment and some are at the beginning. I loved it because it was a nice added bonus. Loved the rear delt in the bonus but went a little lighter since it was my first time, I will go heavier next time. With this upper body workout, you can go very heavy since the reps are less (10 to 12 range) with exception to the bent press where you do 16 reps. I really also like the incline shoulder front raise, v raise, sit up to a lateral raise. I think next time I might try putting lifting gloves on for that just for a little more weight. My 5 lbs felt a little light but I think 8 might be too much. Not sure but I cannot wait to play around with all these new workouts. I think this might end up being my favorite series yet. Thank you so much Cathe for continuing to do the most excellent job you always do.
