Fat Gripz EXTREME are insane. If you haven't mastered your lifts with
the original Fat Gripz then you won't be able to handle the EXTREMES.
With a full 3/4 inch increase in
diameter the EXTREMES push your grip and arm strength to the limit.
Which means that they are not for everyone, only for those who want to
get jackt arms and are willing to work seriously hard for it.
Please don't buy Fat Gripz Extremes (orange) unless you have been
training with Fat Gripz Original (blue) for at least a few months OR are
purchasing both together as a planned progression.
