FAQ
- Why not just test a max?
- A true 1RM needs a spotter and a good day. Epley is for programming from a 5-rep set.
- High reps?
- The formula gets sloppy past ~10 reps. Use a heavier set.
- Do you store what I type?
- Browser tools stay in this tab. Refreshing the page clears the form. Nothing is saved to a Pulse account.
- Is this free?
- Yes. Pulse stays free because of advertising. Ads may appear when you copy, download, or run the main action.
