Anybody else feel like they can do so much more if their body would just behave?! I've been really ready to increase my exercise intensity but every time I try either my knee gets out of whack, or I get shin splints, or have an asthma attack. Am I going to be stuck doing low-intensity forever?
If I increase the intensity/frequency too quickly, then my arthritis acts up. Try increasing the intensity just a little and work at that level until your body is accustomed to it. Or try increasing the duration by a few minutes at a time, depending on what kind of exercise you are doing.
It takes longer to progress this way, but it's better than having to take breaks in between.
