I absolutely love my workout exercise ball. I did a small blog about the ball http://mysheriannblog.blogspot.com/2012/10/love-ball.html on a previous page but I have to share how much this ball is actually helping! I work from home and on the phones for hours at a time, after work I spend hours working on homework- THAT'S A LOT OF SITTING. During that time I've been finding small ways to create a calorie burn but still be productive with work and school.
Sitting on the ball automatically works the ab muscles which helps to also strengthen my back. While working I'm able to do move around on the ball, leg lifts, ab, squats, and core exercise. There's something about sitting on the ball that creates a healthy mindset to find ways to move while working. This also brings awareness to my posture unlike my executive comfy office chair (slouch!). Just sitting and working is burning calories!
I did some research and learned that 1-hour sitting on the ball can burn 100-200 calories per hour! Well this is GREAT since I'm working for hours at a time. GET MOVING EVEN WHEN YOU HAVE TO SIT TO MAKE A LIVING!!!!!
Many do not have the luxury of bringing a ball in the office to work so I recommend using the ball during television, sitting projects, and even hanging out in the living room with the fam.
