While most workouts will definitely challenge you, few will really put your strength, endurance, and overall fitness to the test.

This circuit is one of those few.

Even though it has just four moves—single-arm squat and presses, elbow planks, dumbbell rows, and controlled mountain climbers—it's going to attack almost every single muscle in your body. Get through six rounds of this in just 30 minutes without stopping for longer than the allotted rest periods, and you're in ridiculous shape. If you can't (and hey, no shame), then incorporate it into your fitness routine until you're able to crush it.

Directions

You'll do this workout as a circuit, meaning you'll complete each exercise consecutively without rest. Once you've finished all exercises, rest for 30 to 60 seconds. Repeat the entire circuit for four to six rounds.

Depending upon your ability, you may shorten or lengthen the rest periods between circuits. You may also complete more or fewer rounds.
