built for people who actually lift.

Lock In Iron Log started with a simple idea:

Your workout log should make your next workout easier.

If you trained chest last week, you shouldn’t have to remember what you benched, dig through notes, or scroll through spreadsheets to figure out what you did.

Your last workout should already be there.

Lock In was built to make tracking simple — log your sets, see what you did last time, build on it, and get back to training.
