Kris has checked in to reply to Peggy's question about shin splints:

Putting some ice/cold packs on the shins after exercise is also a good idea to calm things down from the exercise completed. For everyone, it is more the idea that you are lifting the toes/front of foot off of the floor to work the muscles in the front of the calf area. A good exercise to continue is walking a certain distance on your toes/balls of feet and then turn around and walk on your heels back to your starting position. During the day, a person can stand and raise their heels off the floor for a particular number and then raise their toes/balls of feet off the floor for the same number of repetitions as their heel raises. Anyone that has issues with the so-called shin splint problem, we need to check your ability to balance and also leg/hip and core strength. Weakness in any of those areas can cause excess stress in numerous areas. Anyone that is having any sort of issues, please talk with me so we can stop things before they get worse/more serious.
