I remember when I was young, my brother had an exerciser that was made of spring. It has a handle on both ends that you use to pull the spring in front of the breast. I tried it once but I couldn’t pull the spring because I was still a girl then. I am thinking that maybe I can use that spring to give me energy and also to serve as my tool for exercise. What I am using now is the hand grip which is also like a spring but instead of pulling apart, the hand grip is pressed.
