I have recently started trying to do negative chin-ups in several occasions, but afterwards I feel a mild pain in both my left and right wrists. It is not the kind of "healthy" discomfort of sore muscles, but rather the kind of thing that, when ignored, eventually sets up as a tendonitis.
After a day or two it goes away, then I try again, and it comes back.
This means, not only I have to do negatives in order to gain strength to eventually perform chin-ups, but rather I have to strengthen my wrists first, in order to be able to do negatives...
So, I have two questions:
1) What exercises can I do to gradually and gently gain strength in my wrists?
2) Will the bodybuilding writs wraps help by pulling too? Why and how? Should I wear them always when attempting dumbbell lifting and calisthenics, or would that protect my wrists but also prevent them from becoming stronger?
I have seen this wonderful video of a man performing several chin-ups at age 89, so I am not going to give up (I am 41).
Remark: by wrist straps I mean something like that:
which (I think but it is only a guess) act by relieving some tension from the transverse carpal ligament during heavy lifting. Nothing to do with the straps used to assist the grip in heavy deadlifts.
