About this tool

Eleven free, evidence-based calculators that score the four pillars of healthspan: cardiorespiratory fitness, strength, stability and body composition. Estimate your VO2 max, fitness age, grip strength, sitting-rising score, waist-to-height ratio and body fat, and plan protein, heart rate zones, running pace, fat loss time and muscle kept on GLP-1 medication. Built by Catalyst Performance, a personal training studio at Manulife Tower in the Singapore CBD, where coaches measure all four pillars in person with the 4-Pillar Healthspan Assessment.
