WHOOP 5.0

WHOOP Age — healthspan tracking

WHOOP 5.0 gives you a biological age score derived from your sleep, recovery, and training habits — showing whether your lifestyle is ageing you faster or slower than your years. Updated daily, it makes long-term health trends visible at a glance.

AI Coach — coaching, not just data

WHOOP's AI Coach learns your body's patterns and delivers personalised daily recommendations in plain language — not just what happened, but why, and what to do next. It adapts to your training load, sleep debt, and recovery trends.

Strength Trainer — weight room coverage

WHOOP 5.0 added a dedicated strength trainer that auto-detects sets, measures neuromuscular load alongside cardiovascular strain, and shows recovery demand from resistance training — a gap every previous WHOOP version had.
