A low-tech, low-maintenance way to get in some cardio: jump like Jack Flash and reap the rewards.
Shaped like a boa constrictor (thin in the center and thicker at the sides), with precision super-speed radial ball bearings in the non-slip foam handles; not made for jumping on asphalt or concrete (that's not good for you either).
Comes in two lengths:
- 9-ft. length for those under 6-ft. tall
- 10-ft. length for those 6-ft. tall or over
No. 1381 (.5 lb.) $24.95
