Of the three hamstring muscles, the biceps femoris is injured far more often than the other two.
Most hamstring rehabilitation fails because it never reaches high speed. The muscle must meet the demand it will face.
In a randomised trial of gluteal tendinopathy, education plus exercise outperformed a corticosteroid injection at eight weeks and still led at a year.
Three couplets · two rounds · twelve minutes · hips that drive you
Knees to hip height with a fast turnover, landing under the hips; count the left leg.
Easier marching · Harder faster
Heel snapping to the back of the thigh, knee staying under the hip.
Easier walking version · Harder faster
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 for one second.
Easier slower switch · Harder faster switch
Up the stairs one at a time as fast as control allows; walk down.
Easier walk up · Harder two at a time
Drive off the step to a soft landing on top; step down under control.
