NOW The Better-Fly IS ADJUSTABLE with the innovative BUCKLE DESIGN
The buckle allows easy one hand operation to tighten The Better-Fly™️ to your desired level. However, you can still use it fully opened for any exercises. PLEASE NOTE: The buckle is not intended to make contact with your body! If it does, adjust your cable angle and tightness to avoid direct contact with the buckle.
Innovative Design, Mind-Blowing Versatility
The Better-Fly’s never-been-done-before design features a removable solid support frame, making it the first exclusively elbow-and knee designed cuff in the world. Its revolutionary elbow/knee loading capability positions the attachment above the joint, delivering true single joint isolation for tons of exercises (and you will discover new ones!) targeting your upper, mid, and lower pecs, all three heads of the delt, lats, rhomboids, traps, abs, and even glutes, abductors, and rectus femoris!
The Better-Fly Soars Above the Rest
Unlike any other cable attachment or cuff, The Better-Fly ensures reliable stability and consistent control. Its protective padding protects your arm comfortably, while a rubber non-slip grip keeps it in place during even the most extreme ranges.
NOTE: The soft rubber may create slight redness on your arm at first but this goes away very quickly and you adapt to it over time.
The unique triangle ring allows you to effortlessly adjust the line of force without worrying about shifts or slips, giving you unmatched confidence and focus. This is precision engineering for every lifter who wants the best gains and most effective reps in every workout.

Frequently Asked Questions
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 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 anchor point on your arm 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.
What is a Single Joint Movement?
A single joint movement is an exercise that engages the muscles controlling a single joint as opposed to a compound movement that engages multiple joints. The best example of a compound movement is a bench press or squat. These incorporate several joints and lots of muscles. Because The Better-Fly attaches to the elbow, it bypasses the elbow joint and wrist joint, which enables true single-joint chest, deltoid, and back exercises to be performed. Studies have proven that isolation exercises are the most effective at growing a muscle.
Why do I want additional base plates?
The base plates come in a variety of colors and can be removed and changed in order to coordinate with your apparel for the day! With multiple colors, you can mix and match to represent your favorite team or even a holiday.
