It is generally known that there are more power exercises in armwrestling than in any other kinds of sports. The problem is that athletes train their arms and body parts no more than 3-4 times a week by performing no more than 4-6 exercises per training.
The frequency with which you should train a particular muscle depends in part on how much work (volume) you're doing. Beginners who don't do a lot of sets for a given body part can train them more frequently (say every 2-3 days). More advanced lifters who do 15-20 sets for a given muscle group can follow a split in which they train each muscle group every 5-6 days.
