Forearm Tendonitis caused by P90X and riding a bicycle trainer?

I am experiencing tendonitis in the outside of my forearm near the elbow. It seems to have started at the same time I started riding my bicycle on an indoor trainer. Given that there is no impact or repetetive motion for the arm in this activity, is it possible to get tendonitis just from holding the handlebars while riding?

My other fitness routine is P90X, which I have been regularly doing for the last 18 months. I did experience the same tendonitis last winter, but associated it with P90X. I was riding the bike last year as well.

Hi Andy.

Well, that's the funny thing with Tendonitis. You had Tendonitis with P90X, and you STILL had it afterwards when there was not pain, and you still had the same Tendonitis dynamic which is what you were irritating with, assumably, the grip on the stationary bike.

And depending on what you've done with your hands/forarms/arms in the past, it's likely that you already had a Pain Causing Dynamic in place even before P90X which just took it over a particular threshold.
