Trying new exercise Last Sunday i went jogging in the park near by my house. There are some exercise machines in the park to have people have more choices in doing exercises. The Park have abdominal machine for belly exercise, also it have pull-up bars, the exercise bikes... After jogging, I tried making exercise with abdominal machine and pull up bars. It is just for fun. I think jogging is engough for me. I tryied pull up bars, seems it did not work for me. I could not pulled my body up even 1 time. With abdominal machine, I blend my body 10times, then I got home. One day after that day, my belly get sore. It feels uncomfortable. I think it becAuse I made exercise with abdominal machine for the first time , and my did not adapt with this exercise yet. I think for next few times, I will get use to doing exercise with abdominal machine , and I will not get sores with my belly anymore.
