I'm spending most of the day in front of the computer (10+ hours), and as expected, my wrist tendons experience strain during work. Normally, this wouldn't be much of an issue, but after I have started training more aggressively (especially with free weights), I feel slight pain and weakness in the wrists when they are at unnatural position under load.
The frequency of training is not the issue -- usually at most 3 times per week, and I do torso/arms exercises only twice per week.
Now, the questions:
Which arm exercises are known to put less strain on the wrists? I'm interested in upper-arm/chest exercises mostly, but advice for other muscle groups is appreciated as well.
Is there something else I can do to reduce the problem (training accessories, special exercises, other)?
Edit: I'm doing exercise on the weight machines and cables mostly, some free weights and stretching. No push ups whatsoever.
