Previously, I was using a resistance band that I can place one of my knees in to assist with pull-ups. However, I did not like the balance too much. The new equipment has two separate rest areas for both feet or both knees.....whatever is preferable. I like using my feet because I feel safer with that method. I wish I knew this equipment existed earlier....oh well. I completed my requirements. I do not have all day since I am working the next two nights. Enjoy the rest of your Sunday!!
