A training log built around the one lift you care about.
This started as a program for me and my bench press: one lift, a block of sessions, a number that had to go up. Then a friend asked to use it, so it got sign-in. Then more friends asked, and most of them didn't want to live on bench alone, so it grew a Balanced mode for general training. Now you pick: a balanced routine, or one main lift you want to push as far as it goes. Either way Dot, the little mascot, plans your next session, nags you about the weigh-in, and falls asleep if you don't show up for five days.
Try it: workout.codesaif.dev. Sign in with Google, add it to your home screen.
- Main Lift mode: block periodization for one lift. The main lift is always first in the session; the next load is prescribed from how the last one went, and e1RM (Brzycki) tracks the trend. Feeling strong? Tap any later session in the block view to jump straight to it.
- Balanced mode: training days, muscle groups and exercises of your own, logged the same way.
- Plan with Dot: answer five questions and an LLM rewrites your routine, previewed before it's applied and undoable for a week. Or copy the prompt into your own chatbot and paste the plan back.
- Gym bros: add friends, see their sessions, react and comment.
- Bodyweight check-ins with streaks, and push reminders when you've gone quiet.

Next.js (App Router) on Vercel, Auth.js with Google, Vercel KV for everything synced, and one
cron job for reminders. The Vercel integration deploys main on every push.
