You're busy; you don't have all day to spend at the gym, but you want to get in a good workout and you want to feel accomplished after you've wiped off the sweat. So what are you supposed to do if you only have 30 minutes to spare? Jillian Michaels, celebrity trainer and creator of the comprehensive app My Fitness by Jillian Michaels, is here to save the day.
We asked Jillian what the better choice is when you're short on time — cardio or strength training? Instead of choosing one or the other, Jillian told POPSUGAR you should do "resistance training that is done in circuits combined with HIIT intervals so you get little rest between exercises."
Here's the example Jillian gave us: "30 seconds of push-ups to 30 seconds of weighted squats to 30-second mountain climbers." You can choose any number of movements that you love doing and string them together for a killer workout, like burpees, shoulder presses, box jumps, or triceps dips. If you don't know where to start, here are a few workouts for you to choose from. They're under 30 minutes, and each of them alternate between strength-training exercises and cardio moves.
