Years ago, 405 lbs was my one-rep goal on the deadlift. Now, I use it differently. Rule I follow: If I can deadlift a weight for 10 clean reps, I’m likely ready to pull +90 lbs more for a single. That’s how 405 × 10 reps became my green light for 495 in 2025. Find Your 10-Rep Number (No Math Needed) If your goal 1RM is ⬇️ Use this weight for 10 reps ⬇️ - 225 goal → 135 × 10 - 275 goal → 185 × 10 - 315 goal → 225 × 10 - 365 goal → 275 × 10 - 405 goal → 315 × 10 - 455 goal → 365 × 10 - 495 goal → 405 × 10 If you can own the reps, the max is predictable. Why This Works (Simple Version) - Reps build capacity - Capacity protects joints + nervous system - Strength becomes available, not fragile One-rep maxes should be earned, not attempted. A Better Annual Fitness Plan Instead of asking: “Can I lift this once?” Ask: “What weight can I dominate for reps?” That answer tells you exactly what your 2026 year of training should focus on if you’re planning for PRs.
