I used to run on the treadmill, but that stopped working for me after a while. My husband told me to try some kettlebell workout exercises out. I was afraid to try it at first, but after giving it a try, I am glad that I did. I am toning up more each day and I feel great. I have introduced some others to these exercises and they all like the results that they are getting too, so I know they can work for others.
