Can circuit training replace cardio?

Yes, it can, as long as you’re training with high intensity. If your circuit includes exercises that elevate your heart rate (burpees, fast-paced squats, mountain climbers, or jump lunges) and minimal rest periods between exercises, you can get a solid cardio workout while still building strength. However, if your goal is to improve on a specific type of cardio, such as running longer distances or swimming for a specific duration, it’s still important to frequently run or swim. You’ll still want to train for the sport or individual goals that you may have. However, for general fitness enthusiasts, circuit training can definitely cover most of your cardio needs.

What is an example of a circuit training session?

A simple example looks like this: 45 seconds of squats 10-second rest/next up 45 seconds of push-ups 10-second rest/next up 45 seconds of lunges 10-second rest/next up 45 seconds of planks 10-second rest/next up 45 seconds of mountain climbers Rest for 1 minute, then repeat the whole thing 2-3 times. This is a full-body circuit. You’ll move from one exercise to the next with minimal rest, so your muscles and heart rate stay engaged the whole time.

Is weight circuit training effective?

Yes, it can be. Using weights in a circuit can boost both strength and cardio benefits at the same time. You can get the muscle-building stimulus of resistance training and the heart-pumping effect of moving quickly between exercises.

Is 20 minutes of circuit training enough?

For most people, yes. A well-planned 20-minute circuit can be surprisingly intense. You can improve your strength, endurance, and body composition with short, high-effort sessions.
