I've always used a logbook for the gym, usually whatever notebook I had laying around the house when I needed it. The problem was writing out what my workout plan was before I go to the gym was just another blocker, something that I need to do before I can just go and work out.
This resistance is the last thing I want! So I decided to fix that by creating Logbook Forge! Generate a completely custom logbook based on your actual workout plan, ready to go.
