how you actually train.

Every feature in CritLift is designed around the science of progressive overload and real-world training.

AI-Generated Programs

Answer a few questions about your goals, schedule, and equipment. CritLift builds a complete multi-week periodized program tailored to you.

🎯
Real-Time Auto-Regulation

Rate of Perceived Exertion (RPE) guidance adjusts your working weights between sets, so you always train at the right intensity for that day.

🔄
Weekly Adaptation

After each week, CritLift analyzes your logged sessions and updates your next block's target weights. Your program evolves as you do.

📈
1RM Progress Tracking

Track estimated one-rep maxes across all your main lifts over time. Charts, history, and trends so you can see exactly how far you've come.

From setup to
PR in four steps.
