Just recently purchased No.1 Captains of Crush® Gripper, Expand-Your-Hand Bands™, The new "Blueprint for Grip Strength DVD" from Ironmind. COC are great products. They are simple and effective. Someone at my gym stole my COC 1 but it was my fault was leaving it out there alone. I hope the thief is getting better at his grip strength. The extend-your-hand rubber bands seem fun and just what I needed because I do alot of clubbell work. I will you guys the 411 on the DVD. Happy holidays, folks.
