TESTIMONIALS "The Kinetic Arm has been a lifesaver for some of my athletes, especially if they were experiencing discomfort when throwing. They lit up after using the K2 Sleeve because they said they did not have pain and throwing felt more effortless. I noticed an improvement in throwing consistency and less fatigue in practice. I highly recommend this for quarterbacks." Charley Loeb Quarterback Coach "My son was diagnosed with little league elbow and doesn't play baseball but he does play football. He was struggling with his form breaking down when fatigued and protecting his elbow while throwing. So I researched this device ALOT. My son said it felt "weird" when he first tried it but he didn't have pain or feel stressed with throwing for the first time in weeks. He now carry's it in his backpack and never throws without it. This device is amazing and keeps his arm and the tendons/muscles protected in the proper position." Jonathon Muszynski Football Parent "This has really helped support my son's shoulder so he can continue to play and do what he loves." Lorna Alvarado Football parent
