This fellow lady boss is the queen of arms! Let's face it ladies, no one want to walk around this summer with turkey triceps and slouchy shoulders. I love, love love this workout from Kat, she combines weight training, cardio and lower body that will just leave you tired, but wanting more. She's great to train with and makes me sweat like no other! So take some time and RAAWWWRRRR with Kat this week!
