Speed Box Squat
Muscles worked
Instructions
- 1Attach bands to the bar that are securely anchored near the ground. You may need to choke the bands to get adequate tension.
- 2Use a box of an appropriate height for this exercise. Load the bar to a weight that still requires effort, but isn't so heavy that speed is compromised. Typically, that will be between 50-70% of your one rep max.
- 3Position the bar on your upper back, shoulder blades retracted, back arched and everything tight head to toe. This will be the starting position.
- 4Unrack the bar and position yourself in front of the box. Sit back with your hips until you are seated on the box, ensuring that you descend under control and don't crash onto the surface.
- 5Pause briefly, and explode off of the box, extending through the hips and knees.

About Speed Box Squat
The speed box squat is a dynamic-effort training method popularized in powerlifting, where you briefly sit down onto a box before exploding back up, with elastic bands adding accommodating resistance. Unlike a classic squat trained for maximal strength, this method uses submaximal loads (50-70% of max) moved as fast as possible, developing power and rate of force production rather than raw strength. The pause on the box eliminates the stretch-reflex bounce, forcing the muscles to generate all the needed force from a static position. It's an advanced training method, typically built into a strength-sport competition prep cycle. Reserved for lifters who already have a solid squat strength base.

lightbulbExecution tips
- lightbulbChoose a load between 50 and 70% of your max to preserve speed
- lightbulbDescend under control but explode upward without hesitation
- lightbulbDon't bounce off the box, pause clearly
- lightbulbCheck band tension before every set
warningCommon mistakes
- warningLoading too heavy, compromising execution speed
- warningBouncing off the box instead of a real pause
- warningNeglecting band tension before starting
- warningSacrificing technique in the pursuit of speed
helpFrequently asked questions
Why use a light load if the goal is strength?expand_more
Because the goal here is speed and rate of force production, not maximal strength, which requires a submaximal load.
Do I really need to sit on the box?expand_more
Yes, a brief but real pause eliminates the bounce and forces the muscles to generate all the force from a static position.
