Polar Vantage V3 is one of the few sports GPS watches with on-demand ECG — usually only found on lifestyle smartwatches.
Running power measurement without a foot pod or chest strap — a significant training metric for pacing effort on hills and varied terrain.
The most detailed training load analysis in any sports watch: muscle groups targeted per session, recovery status per muscle, and long-term load trends.
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.
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.
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.
The right pick depends on what you optimize for.
