Frequently asked questions
What is the concentric phase of a lift?
It's the part of the rep where the muscle shortens as you lift the weight — for example, standing up out of a squat or curling the bar up.
What's the difference between concentric and eccentric?
Concentric is the lifting phase where the muscle shortens; eccentric is the lowering phase where it lengthens under control.
Should you lift the concentric fast or slow?
Many lifters drive the concentric with force to move the weight, then control the eccentric on the way down, though tempo depends on your goal.
