Abdominal muscle pain.

I initiated using the Nike training app on the 5th of July 2013.
Nike Women – Nike Training Club (NTC): “Sofia Boutella’s Fearless Workout” (2012-2013)
When I started it, I couldn’t finish the whole program because it was so difficult my abdominal muscles started to hurt. So I was keen to completely master it. It’s only a 15 minutes program but if I do it, I absolutely get muscle pain the next day. I had been doing it 2-3 times a week until I finally memorized it. Now I do it only 1-2 times a month. One day, I thought I would share it with my friends. Unfortunately, my favorite workout program does not exist anymore because it had updated. Some applications updates often disappoint me. I know I don’t have any right to argue that I don’t want to change the specification of the app and that it didn’t infringe any user’s right. (because it’s free) I gave up sharing it with my friends. I feel this program’s value has increased more than before since it is discontinued.

Title: Abdominal muscle pain
I initiated to use the apps of Nike training on the 5th July 2013.
Nike Women – Nike Training Club (NTC): “Sofia Boutella’s Fearless Workout” (2012-2013)

When I started this, I couldn’t ingest the whole program of this workout because it was so painful to my abdominal. So I had keened to completely mastered it.

It’s only 15 minutes program. but if I did it, I absolutely got muscle pain on the next day.
I had been exercised 2-3 times a week until I memorized it. Now I do it only 1-2 times a month.
One day I thought I wanted to share it with my friends.
Unfortunately, my favorite workout program does not get any more. Because it had updated. Some application’s version up often disappointed me.

I know I don’t have any right to argue don’t want to change the specification of the app and that change didn’t infringe any user’s right. (because it’s free) I gave up to share it with my friends. However, I’m curious that this program’s value has exaggerated estimate for me more than before.

words to practice: initiate, ingest, infringe
