I have such specific hobbies that I list here tailored training for each muscle group, many of them are hardly known within practioners. I am working on this and trying to find proper anatomic names to each muscle(s).
Also I use wrist supports (you can find in MMA shops) when my wrist may get irritated, this has helped me to train my arms and fingers and not injuring wrists!
Sports
Golf
Back-swing muscle training
- behind-back traditional-tricep-training bar-over-head with inverse grip: does not train tricep but the small twisting muscle (use
very small weights!)
....... I fixed a backhand pain with this exercise.
....... TRAINS: grip, little muscle used in backswing/forearm.
Tennis
Forearm strengthening for forehand: barber curl (thumbs up/down) and general forearm training.
........ I alleviated my Ulnar Nerve by this.
Fencing, Hockey, Boxing -- sports where pain easily in the top of the hand
String tensions for hands
String tensions for fingers.
........ before starting training, they remove pain by increasing the blood flow and make sure you are not injured. There are very very
small string tensions for fingers that I like a lot!
