Frequently Asked Questions
Should beginners test their 1RM?
▼
No. Beginners lack the technique and body awareness for safe maximal attempts. Calculate 1RM from 8-12 rep sets and use it for programming only.
How accurate is 1RM for beginners?
▼
Less accurate than for experienced lifters. Your technique improves rapidly, so calculated 1RM may underestimate true potential. That's fine - be conservative.
How often should I recalculate as a beginner?
▼
Every 2-4 weeks. Beginners gain strength rapidly, so estimates become outdated quickly. Recalculate when you exceed your programmed reps.
What percentage of 1RM should beginners use?
▼
Start at 60-70% for sets of 8-12. Focus on form. As technique improves, gradually increase to 70-80% of 1RM.
When can I test my actual 1RM?
▼
After 6-12 months of consistent training when your form is solid. Even then, work up gradually - don't jump straight to max attempts.
