PUMPZZ vs RoundBlitz

PUMPZZ turns your lifting into one number — a Strength Score from 0 to 999 — and tells you exactly what to lift today. Exact weight. Exact reps. Log the set, and the next target is already picked. No spreadsheet math. No "add weight or add reps?" debate between sets. You show up, hit the targets, and watch the number climb from Foundation to Elite. PHYSIQUE SCORE Your physique gets a number too. Take one photo and get a 0–999 Physique Score: every visible muscle group graded, with notes pinned right on your photo showing what's developed, what's lagging, and what to train to fix it. Add back and side poses for the full analysis, rescan later, and watch the score move. Photos are stored only on your device — scans are processed securely and never saved on our servers. PROGRAM LIBRARY Start a proven program in two taps: Wendler 5/3/1, nSuns, GZCLP, 5x5, Reddit PPL, PHUL, PHAT-style, upper/lower, full body, and more. Percentage-based programs set up your training maxes for you and handle week-to-week progression automatically — no percentage math between sets.
