PROGRAMMING THAT WORKS. RESULTS THAT SPEAK.

Every feature in G.R.I.T. is built around one goal: helping you add muscle smarter, not just harder.

ADAPTIVE

EVERY WEEK

EVERYTHING YOU NEED

BUILT FOR HYPERTROPHY. NOTHING ELSE.

Muscle Priority System

Tag each muscle as Emphasize, Grow, or Maintain. G.R.I.T. auto-adjusts volume and exercise selection so every session drives the right adaptations.

Auto-Generated Programs

Set your schedule, select your exercises, and G.R.I.T. builds a full multi-week program — complete with progressive overload built in from week one.

Week-Over-Week Progression

Track sets, reps, and weight across weeks. G.R.I.T. surfaces your progress so you always know when to push harder and when to deload.

In-Workout Feedback Loop

Rate pump, soreness, and effort after each session. Over time, G.R.I.T. learns what works for your body and refines its recommendations accordingly.

Personal Record Tracking

Every PR is automatically detected and logged. Watch your strength milestones stack up across every exercise in your library.

Quick Workouts

No program? No problem. Log a free workout on the fly with full exercise history and set tracking — no setup required.

THE G.R.I.T. METHOD

Train, log, rate. Over time G.R.I.T. builds a picture of how your body responds — which muscles grow from what volume, which exercises deliver the best pump — and feeds that back into your next week's program.
