Cable Weight Variations
Zeus 8.6 – IDEAL FOR INTERMEDIATE TO ADVANCED LOOKING FOR A GOOD PUMP
The Zeus cable weighing 1/2 pound per 9ft section was developed to add intensity to your double unders. When exercises become easy they're proven to no longer affect the body. Adding resistance to double unders can completely change a work out as demonstrated in the 2016 CrossFit Games when heavy double unders with a rope inspired by the Zeus rope were first performed. The Zeus cable will develop stabilizer muscles while still provide a cardio based workout infused with the resistance training of weight lifting. This cable was carefully selected to ensure the user can still perform fluid double unders yet not alter the jumper's technique or mechanics. Can you tame the Gods? This rope comes in limited cable colors and is only available with Black Handles with Zeus logo tape.
Kronos 16.2 – IDEAL FOR ATHLETES LOOKING AT UPPING WORKOUT INTENSITY
Move over kids, Big Daddy Kronos is ready to dominate with his 1 pound cable per 9 foot section. Kronos will undoubtedly push your high intensity work outs to the max with as much resistance as you can handle. Double unders with a 1 pound cable will not only develop grip strength and muscular stamina but will also force you to develop efficient technique and mechanics or suffer the wrath of the gods. Can you tame the Father of the Gods? This rope comes in limited cable colors and is only available with Black Handles and Kronos logo tape. Only sold in sizes 8'0", 8'4", 8'8" and 9'0". Please refer to our sizing recommendations for the best fit.
