Wow! You have already made it to Week 3 of my Summer Challenge Fitplan, and by now you should really be feeling a bounce in your step after two weeks of solid hard work. We are going to keep the intensity high, starting the week off with some new moves, including a few great combos. You're going to love the single leg pulsing glute bridge - they are killer for both the glutes and hamstrings. Now go out there and sweat it out!
