Dispositif d'exercice physique à porter sur soi comprenant un harnais (16) constitué d'une pluralité de sangles (10, 12 et 14) pour recouvrir une région de torse supérieure (20) d'un utilisateur, une pluralité de câblages reliant une pluralité de capteurs, comprenant des capteurs de photopléthysmographie (24), des capteurs de pléthysmographie d'inductance (26), des capteurs d'électrocardiographie (28) pour une dérivation unique ; des positions non indiquées pour 6 dérivations, des capteurs d'électromyographie (30), des capteurs de mesure inertielle (32) intégrés dans des sangles (10, 12, 14), avec une unité de commande (22) pour analyser divers paramètres physiologiques de l'utilisateur. Un module de communication (40) établit une connexion sans fil entre un dispositif utilisateur et l'unité de commande (22) pour transmettre un résultat de l'analyse des paramètres au dispositif utilisateur. Une source d'alimentation (42) alimente le dispositif d'exercice physique. Un moyen d'extension est configuré entre les capteurs (24, 26, 28, 30 et 32) et l'unité de commande (22) pour permettre l'ajout/l'extension de capteurs/modules (24, 26, 28, 30 et 32) vers une ou plusieurs parties du corps de l'utilisateur.
