This summer Lee and I posted a lot on the idea of improving your grip strength and I strongly believe that it is one of the best things you can do for recoil management and it is very important for grappling and generally being “manly”.
However… I trained very hard with some great grip trainers and seem to have some damage to some joints. Now my knuckles crack constantly and times I have trouble opening jars due to pain and weakness. (For the record I over-trained, it wasn’t the tool… never blame the tool).
Jess’s most recent post GET A GRIP: THE PROGRAM shows 2 super-sets that use common gym equipment to build grip strength that don’t seem to work directly against your joints. If this is a fear for you, or you have the same issues with traditional grip strengthener that I have had, this could be a good option for you.
