A client came in with weak glutes causing knee instability during her runs. We focused on this specific lunge variation: driving the back knee down while keeping the front shin vertical. This isolates the gluteus maximus and quadriceps of the front leg, building stability from the hip down. 🦵 After a few sessions, her form improved dramatically. Send this to a friend who needs to strengthen their legs and glutes! #fitness #legday #lungeform #gluteworkout #kneestability #lowerbodyworkout
