Why?

Have you ever thought about your workout routine?  Why do you work one body part during one session? (which is totally ridiculous unless it's legs) Why do you spend an hour on the treadmill? Why are you using weight machines and not free weights? Are you exercising or are you training? Anyone can exercise even kids. Training is doing specific exercises with a purpose to achieve a goal. Do you have a goal? Why have you not achieved your goal. Let's say you want to increase muscle definition & you give yourself an hour to workout 5 days a week. You run on the treadmill for 40 minutes & hit the weights for 20 minutes. I would suggest spending the bulk of your time on the weights & cut down the time that you spend on the treadmill. If you have done the same routine for years & can't see a change in your appearance or performance, it's time for a change.
