Simple slip on connection strap. Keeps arms connected during the swing. Say goodbye to flying elbow and chicken wing! An elastic golf training armband shaped like a figure 8 that is one of the simplest yet most effective learning tools ever developed to teach a connected, torso controlled swing. Simply slip the Figure 8 golf swing strap over your arms above the elbows, and you will immediately feel a connectedness of arms and body. When you swing the club, the left arm will feel like it is leading the downswing while the right elbow is being pulled in toward your swing center. The Figure 8 Strap encourages good timing, or proper sequential motion, while helping to prevent over swinging and excessive looseness and teaches the importance of keeping elbows together during your golf swing. These actions tend to help eliminate unwanted casting of the hands while encouraging a strong "big muscle" controlled swing. Practicing at home, or hitting balls at the range, the Figure 8 training aid will quickly and easily help you to build a solid swinging motion. The Figure 8 golf swing strap is available in 2 sizes: Standard and Extra Large As a general guideline, if you are under 200 lbs., order a standard, over 200 lbs., order extra large.
