I tried Chris Freytag's idea of doing 10 minutes on various machines. I wasn't sure if I would feel like I had worked out by spending a few minutes on each. But it made my time at the gym feel shorter and it worked out different parts of my body, mostly sections of my legs (I use my at-home exercises for arms and tummy).

The treadmill was a good start to a workout. I walked on it for 10 minutes for a warm-up, gradually increasing the speed and incline, until I had to full out run (which we all know I hate doing), then I moved onto the bike. The bike burned my calves because I have not been on that machine for months! So 10 minutes was definitely enough. Then off to my favorite, the elliptical cross trainer, which I spent 15 minutes on.

This is definitely a good idea, especially for people who have a short attention span - that's me!
