If you’re in a pinch for time and want to get a good workout in, things can get difficult in a busy gym during rush hour. That’s when you turn to this total-body circuit-style workout. You’ll get the most bang for your buck and won’t have to crowd around the weights or wait in line for a machine. This workout is perfect to get in and out of the gym in under 45 minutes. It prioritizes the most important functional movement patterns (squats, lunges, deadlifts, and presses, to name a few), while ramping up the heart rate and torching fat. Remember, this is a conditioning workout and won’t act to increase strength — therefore it’s not something to use every day if that’s your goal. Still, it’s a great way to challenge yourself and get an effective workout in during tight times at the gym.
