Circuit training is one of my favorite workouts because you can burn a lot of calories and fat while doing a challenging workout with plenty of variety. Circuit training combines high-intensity cardio exercise with strength training exercises to give you a vigorous workout that improves your strength, endurance and cardiovascular fitness.
Here’s a sample 30-minute circuit training workout for runners:
5-minute slow jog to warm up
3 minutes of fast-paced running, at about 85 percent exertion level
2 minutes of push-ups, modifying to do push-ups on your knees if needed
3 minutes of fast-paced running
2 minutes of squats, using dumbbells if you want to add difficulty
3 minutes of fast-paced running
2 minutes of crunches
3 minutes of fast-paced running
2 minutes of lunges, alternating legs
5-minute slow jog to cool down
