This clipboard is a tool familiar to my clients. This is where I keep track of workouts. For clients, it gives me a place to write down record-breaking lifts or thoughts for the next workout or exercises that would be good to add to the repertoire.
When I use the clipboard on myself, I use it a little differently because I make myself work out with myself more than once or twice a week. This is where I write down my goals for the week and where I track what actually happened. The point is, I keep a record. I know that Thursdays are the hardest days to work out. I know I tend to shirk the mat exercises when I do Pilates (so you notice that all the exercises on my Pilates list for the week are mat exercises this time out; I am sneaky like that.).
Set some goals. Track what happens. Learn stuff. Do it again.
