Bio - Stretch before you run and make sure you have the correct shoes. As in if you overpronate when you walk etc. I used to get shin splints when I ran, then I found out that when I walk I overpronate, so swapped out shoes and stretched more and that took care of the problem.
Muscle confusion to build/define muscle and to lose weight. I work out every other day cardio and lift weights..moderate weight until muscle exhaustion. 4 sets fo 12 reps.
