SETUP: Grab a heavy dumbbell and choose which arm you’d like to work first. Hold the weight in that hand, keeping your chest up & shoulders pinned back.
REP: Keep your elbow tight to your sides, and curl the weight up towards your shoulder by squeezing your biceps hard. Lower the weight all the way down until your arm is extended – you should be able to flex your triceps at the end of each rep!
TIP: I like to start with my weak arm, get it out of the way. Also, if you’re looking for a nasty way to torch your arms this exercise can easily transition into a “Run The Rack” Dumbbell Curl (listed below).
