hyperextension
Beyond normal range
Hyperextension is the extension of a joint beyond its normal range of motion—bending a limb backward or straightening it past straight.
It usually describes injuries: She suffered a hyperextension of the knee.
In fitness, hyperextensions are exercises that strengthen the lower back by extending the spine while lying face-down on a specialized bench.
