How tight are your hip flexors?

Hip flexors stabilize and support your lower back, while at the same time letting you lift your legs. Most exercises strengthen your hip flexors in a shortened, flexed position without building strength during extension.

This leaves them tight, which causes injury and discomfort. If you sit a lot, your hip flexors will get tight and then your back will hurt. When the hip flexors are tight, you'll start feeling pain in your joints and sluggishness in your movement.

Hear from our friends:

“With two bulging discs and a job that keeps me bending and lifting, my hip flexors invariably tighten which rotates my pelvis and compress the disc. That’s when I get the classic duck walk and the pain sets in. It used to take therapy to stretch my flexors and align my back. Now I do it at home with the Gravity Flexor, my back is happy and so is my wallet.”
-Mark, Mechanic


“I spend a lot of time in a crouched position so my hip flexors can get really tight. Gravity Flexor does a great job of releasing the tension. I have it attached to my bed so I use it every night!”
-Donasia, Jujitsu



Hear from Professionals:

“I’m always looking for techniques or products that will help my clients deal with tight hips. I was skeptical at first but once I tried it I really saw the potential. I recommend Gravity Flexor to all my clients with hip problems now.”
-Jim, Physical Therapist

“It’s so easy to attach this to my massage table! I use it in between sessions and recommend it to clients with tight hips.”
-Neill, Massage Therapist


Will it attach to my table?

Gravity Flexor attaches to lots of things! Many folks use their metal bed frames as long as their knee can get below their hips.

Some people use a weight bench at the gym. As long as it can support your weight and there are two anchor points, Gravity Flexor will work for you.

The black handles have a circumference of about 13.75 inches (35 cm) and a diameter of about 6.5 inches (17 cm). Carabiners may also be used by they MUST be rated strong enough for rock climbing.

If you can't find anything that works, contact us for help or send it back within 30 days for a refund.

Why not use a resistance band?

A resistance band could help you hold your leg down, but it can't help you do isometric holds (which is where the real magic happens). You have to use something that doesn't stretch.

You also won't get the the knee flexion you need to stretch your rectus femoris muscle (that runs along your quads) so you won't be helping your knee pain at all.

Only Gravity Flexor does both. :)

I think I'm too heavy.

Gravity Flexor attaches to many anchor points! One of our original backers is 6'3" and over 200 lbs! He attaches Gravity Flexor to his bed frame and feels secure. If you are having trouble finding anchor points, send us a message and we'll help you out, or send it back within 30 days for a refund. :)
