The “circuit” in circuit training comes from the fact that you do a sequence of exercises back to back to back, and then you repeat the sequence.
And then again.
You cycle through the planned sequence of exercises, or circuit, multiple times.
That’s circuit training.
Generally you hit each major muscle group during one full circuit. You may do lower body for one exercise. Then upper body the next.
You’ll find all sorts of difference circuit training sequences. Here’s some things most will have in common:
Several different exercises. A normal circuit will have five to ten different movements per circuit. You’ll often hear these referred to as “stations.” Overhead press station, squat station, etc.
Little to no rest in between. The goal of circuit training is to keep your heart rate up. Ideally, if you’re physically able, you go from one exercise to another without stopping. Maybe you rest after the whole circuit. Maybe.
Rinse and repeat. Generally you’ll run through your circuit a few times. Three rounds is common.
