1. High Knees
    High knees give us flashbacks to high school gym class or varsity lacrosse. Those were the days; now we feel a bit more ridiculous doing this move, but it’s a small price to pay for results. Start with your feet hip width apart and your arms in front of you. Engage your core, then lift one knee up to your hand, then switch to the other side. Do this quickly, so you’re basically running in place, for 1 minute without stopping, and keep your abs active and you arms outstretched for a full body workout.
