The Sunny Health & Fitness OB-20 Olympic Dumbbell with Locking Ring Collars will help take your strength training to the next level! It has a weight capacity of up to 150 lb to allow for linear progressive strength gains. The rotating sleeves release torque created by the weight and movement making it safer on the joints. The locking ring collars will secure the weights in place to make working out safer. Get two and perform dumbbell chest presses, shoulder presses, and use just one to perform triceps kickbacks and single arm bicep curls. Increase the intensity of your arm workout with the Olympic Dumbbell for all fitness enthusiasts. Rotating sleeves allow the weight plates to rotate as you move the bar. This provides a more secure grip and reduces stress on your wrists and elbows. Locking ring collars keep everything secured and in place for stability and safety. Diamond knurled handles are comfortable so you won’t shred up your hands while lifting heavier weights. Knurling is optimal for supplementing your own grip strength and helping correct hand placement.
