Calculators and tools
Training Calculators and Tools for Lifters
Use transparent training, plate-loading, and calorie-estimate tools with visible assumptions and conservative limits.
Use a calculator to organize a decision, not to outsource judgment.
Each tool exposes its formula, assumptions, rounding, and limits. Use the output as a starting point, confirm technique and equipment, and stop when symptoms or control worsen.
Working load and warm-up
- 1RM, RIR, and working-weight planner for a recent comparable set.
- Starting-weight guide for ramp sets and conservative decisions.
- RPE and RIR guide for adjusting effort when readiness changes.
Equipment and plate loading
- Barbell plate-loading calculator for equal per-side setups.
- Microloading guide when the next normal increment is too large.
- Dumbbell-versus-barbell guide for choosing the tool before loading it.
Session context and cutting
- Lifting-calorie range calculator with MET assumptions.
- Resting-calorie equation guide so RMR is not confused with workout calories.
- Muscle-retention cutting guide for the larger training and nutrition decision.
