This is a video that kind of shows you what aqua jogging is like. Basically you wear a belt that helps you float so you can run. I went to the community pool today and tried it out. I jogged for about 45 minutes and could have gone longer but there were a bunch of old ladies doing aerobics at the other end of the pool and I wanted to avoid them in the locker room.
Anyway, I thought it was a pretty easy workout that got my heart-rate up and I could feel my muscles getting tired (especially when I got out of the pool). So when I got home I researched and found out I could buy the waistband at Sports Authority for about $25. Which means, for $25, I can go aqua jogging the pool at my apartment complex for the rest of the summer. Sounds like a good deal to me!
I also rode several miles on my bike. I think I'm done exercising today.
