I'm not doing a TA rotation since I like mixing up my workouts. However, I did borrow my sister's Omni and Glute sets. So I did each of those workouts once. I did one Omni and One Glute workout per week untile I tried all the workouts. I didn't take measurements but I noticed that my abs were getting flatter. At this time, I was also doing one Rip:60 workout a week. So I think it was a combination of both.
I liked the results so much that I ordered Abcentrics from QVC. Last month, I weighed and measure myself so I can do a comparison. This past month, I did two Abcentric workouts (I change it every two weeks) a week and one Rip:60 a week. Yesterday (Sunday), I weighed and measured myself. I actually gained a half pound this month
. But I was happy to notice that I lost 1 1/2 inches in my waist and 1 inch in my lower abs. This proved to me that TA abs with suspension training is working for me. I didn't lose any inches in the hips or legs. But I did lose last year when I was mixing barre, Tonique, lots of kbs swings, and plyos. I'm doing the same thing this year so no change there. I also haven't really changed my eating except I was trying to eat dessert only once a week but I'm not very good at keeping that goal.
ETA - I skip abs in barre workouts since I felt they weren't helping me. I only do arms if it's Squeeze or Booty Barre since the weights that are used are heavier. Otherwise, I don't do arm sections in barre workouts either.
