The 90-90 hip hinge starts in the 90-90 hip position—one leg bent 90 degrees in front of you, the other 90 degrees behind—then hinges forward over the front leg to stretch the front hamstring under load. This combines hip mobility work with hamstring stretching in a unique ground-based position that also opens the hips.
When to use it
Use for warm-up, mobility work, or active recovery.
Who it's for
Those seeking hip mobility and hamstring flexibility.
Set up in the 90-90 position with your front shin perpendicular to your body. Hinge forward from your hips, not your spine, reaching your chest toward your front shin. Feel the stretch in your front leg hamstring. Return upright and repeat before switching sides.

Focus on feeling stretch in front leg hamstring.
Keep back leg position stable during movement.
Use hands on floor for balance if needed.
Program 90-90 hip hinges for warm-up, mobility work, or active recovery sessions. They combine hip mobility with hamstring flexibility in one movement. Use them for moderate reps per side. They pair well with standing hip hinge movements.
Rounding the spine instead of hinging at hips.
Changing your back position during the 90-90 Hip Hinge can alter the movement and make the load harder to control. Brace your midsection and keep the torso position called for by the exercise.
Losing the 90-90 leg position during movement.
Hip hinge movements like the 90-90 Hip Hinge depend on a consistent hip path. Keep the load controlled, maintain your brace, and let your Hamstrings guide the movement.
Not engaging core before initiating hinge.
Losing your brace during the 90-90 Hip Hinge can make the rest of your position less stable. Tighten your midsection before the rep and maintain steady tension while the load moves.
Rushing through the movement pattern.
Rushing through the 90-90 Hip Hinge makes it easier to lose position and harder to keep tension on your Hamstrings. Slow down enough to control both the lifting and lowering portions of each rep.
Those seeking hip mobility and hamstring flexibility.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 10-12 reps per side. Rest 45 seconds.
