What are some fun exercises?
Any exercise can be fun . I really enjoy taking a yoga class and I can spend hours on the treadmill and elliptical machine in front of a TV. Just try a few different things and see what you like.
If you are into group activities, try a Tae-Bo or Zumba aerobics class. The extra motivation comes from keeping up with the pace of the class.
Crossfit it's intense but very additive
