This ain't your grandma's workout. If you're serious about eliminating arm flab and building newsworthy muscle definition, do this INTENSE workout! Many exercises are delivered back-to-back with weighted moves followed by low-intensity bodyweight moves. Grab a pair of dumbbells or soup cans. If anything feels too intense, do child's pose.
Doe deze workout met de beste trainingsapparatuur. We raden aan om een bluetooth borstband hartslagmonitor of een smartwatch te gebruiken voor meer trainingsoptimalisatie & prestatietracking.
