Frequently asked questions
- How is 1RM calculated?
- KinesoScore estimates one-rep max with the Epley formula: 1RM ≈ weight × (1 + reps ÷ 30). For example, 225 lb for 5 reps estimates about 262 lb. You can also enter a tested 1RM instead of using the estimate.
- What is an SBD total?
- SBD Total is squat + bench press + deadlift one-rep maxes added together. It is a common way to summarize overall barbell strength and track progress across the three main lifts.
