Super
Stacks are weighted training cups that
can be used many different ways. For most stackers,
Super Stacks operate "like a weighted baseball
bat" by loading hand and arm muscles to a
higher level. After switching back to regular Speed
Stacks, the stacker's hands feel lighter and faster.
Super
Stacks can also be used by stackers with motor
control challenges who might have difficulty handling
regular Speed Stacks because of their light weight.
The extra weight of Super Stacks often gives these
stackers more control. |
