So I've been doing barbell rollups and pinching (from the beginner FAQ program) to build up a bit of strength base and have just been haphazardly squeezing an Ivanko super gripper adjustable gripper to start with grippers, basically doing something like 3x10 3x/week like the instruction sheet recommended. I'd like to start on a formal gripper program and was looking at maybe RRBT which seems to be well liked here. I'm not interested in closing TSG's at this point, just building up a strength base particularly for weightlifting grip and getting my tendons strong, though I'd like to get as high as I can with my ISG closes. Based on my goal and me using an adjustable gripper instead of TSG's which most programs seem to be based on I have a few questions on what I should do regarding a program:
1) I assume RRBT and most gripper programs mentioned here were designed for fixed torsion spring grippers like COC's where there are big jumps between resistances (and variable resistance in the close). Since my ISG has small increments (and a flatter resistance curve) would a fixed gripper based program like RRBT make any sense for someone like me with an adjustable extension spring Ivanko gripper (or similarly a Vulcan or other adjustable gripper)? Would it make sense to follow some kind of simpler more linear program because of the small increments available and pick up RRBT later only after I start hitting plateaus and need more complex programming? And if so what would you recommend?
2) Has anyone come out with a gripper program specifically for Vulcan/Ivanko adjustable style grippers? What are those of you training mainly with Vulcans or ISG's doing?
3) Are the exercises in RRBT all done on the gripper? Or does it lay out thumb/pinch/extensor/block/thickbar/other accessory training to do alongside with the grippers? Am I responsible for continuing to do other training to round out my gripper training or am I supposed to only focus on grippers while running the program? In other words is it something that replaces my entire grip routine or something I plug in just for the gripper portion?
