I got bored with going from swimming to biking and to running on the treadmill (which I regret doing because running on treadmill has given me hip pain) . I set up 5 stations in my gym today and spent about 5 to 10 minutes at each station for two rounds. These are my stations:

1. Stationary bike
2. Stretch cord*
3. Elliptical machine
4. Shuttle sprints
5. Jump rope

* At stretch cord station, I spent 1 minute focusing on major upper body muscle groups - chest, shoulders, and back, each round. For chest, I did standing flies. Shoulders, I did standing shoulder press. And for back, I did three variations of swimmers.

Circuit training kept my workout interesting and intense at the same time. I was constantly challenging different parts of my body. I highly recommend you setting up your own stations in the gym and be a creative guinea pig for your workout.
