I have made up a binder somewhat like Susan's. It has 3 sections. I open it up to today's log (4 weeks on one page, 3-hole-punched, 2-sided) that records which workout I did, and has check-spaces for cardio, chest, back, biceps, triceps, shoulders, lower body, and abs.
So I can tell at a glance how many of each of the above I have done so far that week.
The second section has Excel spreadsheets for each relevant Cathe workout. Most of the cardio ones have no spreadsheet, but IMax 1 does, and Bootcamp. The rest of the worksheets are strength workouts, with spaces for how much weight I used, and some spaces for comments.
The third section is "Times," how long each workout is, how long the sections are, and 30 minute cardios, and groups of workouts that fulfill certain requirements such as "lower and cardio in less than 1 hour," Upper and abs," etc.
I have each workout indexed so I can turn straight to it. Each index is labeled with a Dymo hand label maker so I can read it.
Otherwise I don't really keep track
By the way most of my forms are available free on the web.
