Programming
Advanced programming, built in.
You have full control of the exercises’ periodization, progression, units, and composition. Simple program editing and generation, with every tool you need to author anything from a straightforward block to a complex training regimen.
Click a curve and the canvas re-periodizes every lift in its own unit.
Deloads
Recovery, written into the block.
Program recurring deloads per lift, every few sessions, by a percent or a fixed amount. Miss a lift and Feldt catches it before you save, so you can pull the next deload forward or restart lighter.
Authoring
From workout logging

AI generation
Describe the block. Get the canvas.
Write out a plan or just a goal. Feldt drafts the weeks, lifts, curves and deloads into the editor, matched to your exercise catalog and ready to refine.
Describe the block, or just the goal.
Program library
Featured programs for every discipline.
Proven blocks written by coaches. Run one as written, or copy it and make it yours.
Author it your way
Model the program the way you would write it.
No fixed templates. Any discipline, any unit: contacts, seconds, watts, bar speed or percent. Run as many plans as your season needs.
