Core Strength Test Calculator

Evaluate your core strength with plank holds, curl-ups, or push-ups and track your progress.

Introduction to Core Strength Testing

Core strength tests measure the endurance and stability of your abdominal, back, and pelvic muscles using exercises like plank holds, curl-ups, or push-ups, as recommended by the American College of Sports Medicine. This calculator provides performance scores based on age and gender norms, suggests progressive training plans (e.g., plank 30→60→120 sec), and allows tracking over time.

Ideal for beginners, athletes, or seniors, this tool integrates with our BMI Calculator, RMR Calculator, Lean Body Mass Calculator, and Senior Fitness Test. Export data for coaches or personal records.

How the Core Strength Test Works

Test Types

This calculator uses three tests (ACSM):
- Plank Hold: Time (seconds) held in proper form.
- Curl-Ups: Number of repetitions in 1 minute.
- Push-Ups: Number of standard or modified reps.
Scores are compared to age/gender norms for categorization.

Performance Categories

Based on norms (Mayo Clinic):
- Below Average: Below 25th percentile.
- Average: 25th–75th percentile.
- Above Average: Above 75th percentile.

Training Plans

Progressive plans adjust based on your score (CDC):
- Plank: Increase hold time (e.g., 30→60→120 sec).
- Curl-Ups: Add 5–10 reps/week.
- Push-Ups: Progress from knee to standard reps.
