There's 4 different gripper strengths available with the Trainer, #1, #2, and #3. After receiving all 4 grippers in the mail I rated each gripper and came up with the following results:
Trainer = 54 lbs.
#1 = 75 lbs.
#2 = 107 lbs.
#3 = 151 lbs.
I have attached some pics here for you to view. Notice the torsion springs compared to standard COC grippers and see that the spring is wound the opposite direction.
