Progression style upper body baby! All you'll need are a pair of weights (preferably 5lbs+ or light weights with mods) and a resistance band. WARNING: YOUR ARMS MAY FALL OFF. Hope we can still be friends after this one!
Apologies in advance because this upper body sweaty sculpt is NASTYYY!! Three dynamic circuits mixed with tabata sequences in between. Want to go even harder? Take it up a notch with your heavier weights (I'm using 12.5s)
