7 Circuit Workouts for Endurance Athletes

Written by
Over the past few years, the number of bootcamps and CrossFit gyms offering high-intensity workouts has grown dramatically. If you're short on time, then circuit training is a perfect way to knock out a quick—but effective—workout.

Almost all circuit workouts will engage the entire body, and it's not all about strength training. Even though it's short, expect some tough moments throughout the workout when your lungs are on fire and your muscles are quivering from fatigue.

Besides feeling fit, there are some nice side benefits as well. Circuit training, when done right, will throw your metabolism into overdrive and burn tons of calories. Also, if you're bored with your current workout routine, circuit training can provide some fun and challenging variety.
Circuit Training Defined

Typically these workouts can combine three to 10 exercises that target just about every muscle group in your body. At each station, do 5-10 reps of each exercise using about 40-60 percent of your max capability.

If you're a novice, use lighter weights to allow for proper technique on each exercise. If you're a veteran, push towards the upper limits of ability while making sure you practice a flawless technique.

After you complete all stations (one round) take a quick 30 second to two minute break and repeat the same sequence all over again. You can do anywhere from 3-6 rounds, depending on your level of fitness and the difficulty of the circuit.

Always include a proper warm-up--3-5 minutes of jogging, jump roping or stationary bike--and follow with 2-5 minutes of dynamic stretching. Jump rope and kettlebell swings are included with some of the workouts below--if you're not comfortable with these exercises you can substitute jumping jacks instead.
