I'm supposed to work up to thirty minutes and right now I'm trying to make it feasible through adding on more biking - er, once I get over this bit of being bored silly, which has me shuffling around my workout. The goal is a heart rate over 150, so any exercise or combination thereof is acceptable - I just need to get through the time without giving up, then add five minutes, then another five. I'm aiming for next week for the 25 minute workout - I expect I'll get to 30 some time in June.
I did all biking on either Thursday or Friday of last week, but it was a bit of a failure as my heart rate only got up to 142. Today I did five minutes of rowing (32 strokes per minute, split in 2:25 so quite a bit faster than my time for ten minutes), which got my heart rate up to 160, then got onto a stationary bicycle (as opposed to the stationery bicycle, which isn't strong enough to support a human being and melts when sweated upon). This one actually had a working heart rate monitor, so I could see that I was perking along at 150-153 beats per minute once I got warmed up. That was quite acceptable, I think. God only knows the sweat was trickling down my forehead and arms, so I did feel like I was working.
Lunch now is cold pasta and a salad - pretty tasty, really, and cheap to boot. This gym thing, it sure is keeping my lunch bills down. And I got a look at my thighs this morning and man, I am putting on the muscle (even though I still have lots of fat to ward off the cold, I can see the sleek, powerful stuff beneath it and it is impressive).
