Do you already have a speed rope that you love? Great! This set is the perfect addition. And now with Crossrope 2.0 it is sleeker than ever! Maybe you have improved your single under skills, but are still struggling to be consistent with your double unders. Perhaps you have improved your double unders, but not to the level that you want to be at. The Double Under Domination Set will get you to that next level. With this set you get the Stamina (5.0 oz), Explode (0.75 Lb), and Power (1.25 Lb) cables. The Stamina cable is still fast though it is two to four times the weight of most speed cables. This means that beginners will benefit from the added weight feedback for learning proper double under timing and coordination. More advanced jumpers will still be able to knock out double unders, but will benefit from the higher workload of this rope. The Explode and Power cables are perfect for developing wrist, forearm, and shoulder strength, while you refine your single under technique as you prepare for the challenge of true heavy double under training. When you compete or workout with your speed rope at the end of 8 weeks, you will be amazed at how much lighter it feels and how much faster and more efficient you are. (And if you don"t have a speed rope, pick up the CrossRope Speed rope with this set) Don"t let your skills and ability plateau. There is no secret to the effectiveness of this set and program. Your hard work with heavy rope training will give you great results. - Quick handles have stainless steel ball bearings from smooth rotational action. (Weight: 5.75 oz) - All cables are labeled with the cable name, weight and length for easy reference.
