As someone who trains women worldwide, I HIGHLY recommend The Better-Fly attachment. It hands down has been the best attachment to help activate my glutes over products I have bought in the past from other companies.

After a major achilles surgery, I was becoming really depressed by the decrease in strength and mobility. Luckily, I found the Better-Fly, which has been a GAME CHANGER. I can do all of my lower body work completely pain free, It's nice to know that my entire lower body doesn't have to suffer just because of a tendon injury!...10/10 would recommend The Better-Fly to anyone with an ankle injury.

The Better-Fly helps users target the glutes more effectively. Hip extension is complicated because many muscles are involved. Using The Better-Fly, you reduce the contribution of the lumbar extensors, quads, and hamstrings, shifting the load onto the glute max. As an exercise physiologist, I highly recommend The Better-Fly.

How does The Better-Fly work when it doesn’t strap tightly onto your arm?

The unique design of The Better-Fly allows it to grip onto your arm with its interior rubber lining. The innovative BUCKLE allows the strap to be tightened to increase contact with your arm, but the BUCKLE is NOT meant to make contact with your arm or leg. If it does, you need to loosen the buckle or change the angle of the cable.

The main thing to remember is that any new device takes time to learn and understand. Various cable angles and standing positions will alter the effectiveness of the grip and the stability of the device. If you are encountering movement up or down your arm, adjust the buckle or the device's position on your arm or leg first, then adjust the pulley position of your cable machine, then adjust where you stand in relation to the the pulley.

By experimenting with these variables, you will find a position where The Better-Fly is secure and remains in place throughout your range of motion.
