Team SELF Challenge Day 25: Full-Body Cardio Circuit

If you've ever watched a boxer in action, you know that they have both power and stamina. Sure, they work to strengthen their arms, but boxers also rely heavily on cardio and core movements to get in shape for the ring.

Today’s full body cardio circuit will have you doing the same. Don’t worry, your arms and legs are still going to feel the burn during this circuit, but this workout will tax your abs while cranking up that heart rate. Consider it a one-two punch! And if that’s not enough, we’ve even included a signature boxing combo, the jab to uppercut, for good measure.

The workout below is for DAY 25. Don’t forget to check out the full month of workouts here, or go to the workout calendar here.

Workout Directions:

Do each move below for your selected period of time and rest. At the end of all the moves, rest for 60 seconds. That's 1 circuit. Do the entire circuit 3-5 times.

• Option 1: 30 seconds on, 30 seconds off
• Option 2: 40 seconds on, 20 seconds off
• Option 3: 50 seconds on, 10 seconds off

Bonus: 4- Minute Burnout

Do each exercise below for the indicated number of reps as fast as you can. If there's any time left over, hold a forearm plank until the clock runs out. For any move repeated on both sides (like skaters), each side equals 1 rep.

• Jumping Jack
• Bicycle Crunch
• Squat Pulse
• Inchworm
• Forearm Plank
