Cluster
Description
The barbell cluster (also called a thruster) is a CrossFit staple combining a barbell front squat and overhead press. You squat down with the bar in the front rack, then explosively stand up and press the bar overhead in one fluid motion. It is a brutal full-body exercise.

- Sit your hips back and down into a front squat. Keep your chest tall and elbows up.
- Descend until your hip crease drops below your knees.
- Drive explosively through your full feet to stand up.
