Summer = Get fit!

So, I have wanted to get back into running. I haven't really run since 7th grade track, but only because my knees and feet are really bad. I also need to strengthen my core muscles to improve my posture and help me be able carry the snare drum during drumline this fall. Not to mention the good ab workouts that double as core workouts! =)
Here's the plan that I came up with. All plans are subject to change without notice! =)
I hope to be able to stick to this throughout the summer!
