Throwback Thursday.
Here is an excerpt from my training journal 15 years ago.
Consistency is the key!
Do you do this because you genuinely find it useful or because you have OCD?
I find it useful keeping a journal log when joining a new gym for maybe 4 to 6 weeks because it's new equipment and even free weights can feel a little different.
After that you know what you need to do weights and reps wise without having to think about it too much, and the journal becomes a bit pointless.
