@dr.lisa.dpt: For a full contraction, improve your hip internal rotation since the glute max contracts into external rotation. I like to think of it as a swinging door- for the full contraction it needs the full range as rotates from internal rotation to external rotation coupled with hip extension #runtok #runningtips #runningtipsdaily #glutestrength #glutemaximus #runningformtips #marathontraining #marathonrunner #itbsyndrome #hippain #hipmobilityexercise
