Kicking is the classic mechanism

Kicking is the classic quadriceps mechanism — so it is rehearsed in stages, slowly, before it happens at speed.
Quadriceps strains most often happen in kicking and sprint acceleration, when the muscle is lengthening under high force.
It bends the hip and straightens the knee, so it is stretched at both ends during a sprint or a kick — which is where it tears.
Building strength in a lengthened position transfers better to sprinting and kicking than strength in a shortened one.
Three couplets · two rounds · twelve minutes · a thigh that holds
Knees to hip height with a fast turnover, landing under the hips.
Easier marching · Harder faster
Hand on a wall; swing the leg forward to hip height and control it back — no snap.
Easier smaller swing · Harder higher swing
Hands on a wall, body leaning; hold one knee up at hip height, then swap.
Easier shorter holds · Harder lower lean
In the same lean, switch the legs fast and hold the new position one second.
Easier slower switch · Harder faster switch
Hand on a wall; swing the straight leg forward and back through a free range.
Easier smaller swing · Harder bigger swing
Swing the leg across the body and out, hips square, through a controlled range.
Easier smaller swing · Harder bigger swing
