Most of us have trained at one part in our lives. Chances are if youíve ever taken your training seriously youíve used a training journal or a training log.
The main difference between training journals and training logs, is what you document in them after each workout or day, etc. Training journals are just that. They are more of a journal rather than a log. They will normally include things like mental health and how you felt during day or your workout. They can reach a bit into some statistical information but this is normally saved for a training log.
Training logs are generally created of off some kind of a template. For example. Everyday you fill out a form that has same fields. Things like current weight, daily workout, diet information, are all things that can be put in a training Logon a day to day basis.
I wouldnít recommend going all one route or all other, both journaling and logging are important to keep an effective history of your past. Iíve found out through experience and that for convenience sake itís nice to have two combined together in some way. This way itís always easy to remember to do both.
