Maybe you are resistant to exercise. Or maybe you have a friend that is resistant to exercise. Try this one though, how about using your friend to make the resistance in resistance training.
I found this great partner workout for you to check out. It has exercises for all parts of the body to be done with a partner supplying resistance for you to work against. Both people are working in each exercise.
Try it with a friend or your boyfriend. The benefits of this routine are no equipment is necessary.
