This shirt gives me such a powerful attitude at the gym. I love it. Tonight I rocked out to 6 rounds of 400m sprints and 20 Russian kettle bell (or a dumbbell) swings with 25lbs. I was dripping sweat by the end. That is what happens when you are late to spin class and no bikes are available. Thought about that workout on a whim and boy was it a good one!
