1Body & strength
Back Squat is the reference. Trap Bar is converted conservatively to a squat-equivalent estimate.
Use a hard but controlled set of 1 to 6 reps. The calculator estimates your 1RM automatically.
2Jump profile
CMJ vs SJ helps estimate how well you use your elastic system.
3Body composition - optional
Body composition is only treated as a performance context, not as an aesthetic target. Do not chase weight loss if it reduces strength, recovery, or training quality.

This tool is an educational estimate, not a lab diagnosis. Real jump performance also depends on technique, fatigue, injury history, mobility, coordination, and sport-specific skill.
