 Choosing a Zenith gripper:  use Zenith by itself or along with a CoC or IMTUG gripper, depending on your goals: 
-   Strength and conditioning :  use the same Zenith model you are using for your work sets with a Captains of Crush gripper as a starting point--so if you are doing your work sets with a CoC No. 1, try a Zenith 1, and then go up or down, depending on your preference
 -   Fitness : select a Zenith one step down for conditioning and active rest, warm-ups and cool-downs, prehab and rehab work 
 
 
Made in the USA.
Zenith 4:  If you do your work sets with a Captains of Crush No. 4, this is where we recommend you begin with Zenith grippers.  It will be easier to close than a CoC No. 4, and that's by design.
