Programming that adapts to your training, not the calendar.
Most powerlifting programs are written once and followed rigidly, like a spreadsheet that assumes every session goes as planned. LiftNlog was built on a simpler idea: your program should react to what happens under the bar.
Every RPE and technique rating you log feeds into your next session. Top sets, back-off weights, accessory volume, and the taper into your peak week all adjust automatically. There is no manual math, and no need to rewrite your program when a session does not go to plan. The Features page explains how the engine handles loading, tapering, and accessories.
Who builds it
Enrique and Collin build LiftNlog. Both are competitive powerlifters. It started from one shared frustration: they rebuilt the same periodization spreadsheet by hand every training block, then fixed it by hand every time a session did not go to plan.
The app is opinionated by design. We are a small team, and our focus is the LiftNlog app for iOS and Android, ahead of launch.
The methodology
LiftNlog's engine uses RPE-based autoregulation from the RTS (Reactive Training Systems) methodology, the approach associated with Mike Tuchscherer. Here is the short version. You rate how hard each set felt on a 1–10 RPE scale. LiftNlog compares that rating with the target for the set. The difference updates your estimated 1RM and the weights for your next session. It is the same model we wanted for our own training, not a generic percentage table bolted onto a workout logger.
We claim no affiliation with RTS. We think the method is sound, and we built software that applies it consistently. You do not run the RPE-to-percentage math by hand. The RPE chart explainer shows what that math involves.
How we write about training
On the blog we write about RPE, autoregulation, and powerlifting programming the way an experienced lifter explains it. That means direct language, no filler, and no invented statistics or studies. If something is a rule of thumb and not settled science, we say so.
