arc vs alpha progression
the short answer.
alpha progression is a hypertrophy-focused plan generator that recommends your next weight and reps off your history. arc does the beginner half better: a trainer-style intake, a program built from it, and a walkthrough for every set. arc is free.
feature comparison.
why arc.
alpha progression is a sharp tool once you know your way around a gym and want to squeeze more out of your training. arc is aimed a step earlier: you tell it your goal, your equipment, and how long you've been lifting, it builds the split and picks the exercises, and it walks you through every set while you learn the movements. no subscription to find out whether it fits.
how alpha progression differs.
alpha progression generates science-based plans and auto-recommends target weights and reps from your logged history, with deep volume and progression analytics. it's built for hypertrophy optimization and assumes you're already training consistently. it runs $12.99/mo or $79.99/yr.
the bottom line.
if you're already lifting regularly and want progression analytics to push further, alpha progression is built for that. if you're earlier than that and want a plan plus a walkthrough for free, start with arc.
