The Aerobic Side of Fitness
For most of us, our fitness goals are modest. We want the physical capabilities, including strength and endurance, to engage in recreational sports or just to make it easier to perform daily activities. A well-balanced fitness program combines aerobic exercise three to five times per week and strength training two to three times per week.

Ask The Expert

Yesterday morning, I was hit by a baseball on the inside of my knee causing a great amount of pain. Later in the day, the knee swelled up and I iced it. I also started running a low fever (100.5 F) that was reduced by taking Advil. Now, more than 24 hours later, the swelling has not gone down. I can’t put much weight on the leg. If I stop taking Advil, the fever returns. Are my symptoms related to each other or is it just a coincidence that I became feverish at the same time I got hit?
