Free fitness tools

Small, free tools that each do one thing. There is no sign-up and no email box, every figure is worked out in your browser rather than sent to us, and the sources behind the numbers are named on each page. Built by the team behind Trael, the UK AI fitness and diet coach.

Trael provides general fitness guidance only and is not a substitute for professional medical advice. Always consult a doctor before starting any exercise or diet programme.
