Tennis elbow is inflammation of the common extensor tendon in the forearm and the tendon attaches at the elbow. The muscles that extend the wrist and fingers share this common tendonous attachment and it's quite common for inflammation to occur to this tendon from overuse, bad form, improper hydration, and just plain too much weight.
Tennis elbow would be on the outside of the elbow... on the inside it is called Golfer's Elbow. I had a big bout with tennis, and a little trouble with golfer's myself. And I don't play either. LOL Anyway, what I found to help was alternating pullups and chinups, and stretching it whenever I felt it twinge.
Golfer's elbow too (the opposite side of the joint). I learned to do twisting db curls: start with a hammer curl grip then turn when the db is almost up. An ez curl bar may help. You just have to lay off the movements that bother it, ice it and take anti-inflammatories (aspiring, ibuprofen, whatever you like).
Tennis elbow is an all-too common affliction suffered by hardcore bodybuilders / strength athletes. When Science Editor Lonnie and I talked about presenting this piece to VM readers, its message took on a whole new intensity of importance: Fortress is suffering from what he believes is "tennis elbow".
Take Ibuprofen everyday and especially before a workout. I took a week and a half off, kept swelling down and returned and slowly worked back up to heavy curls. Your tendons needs to heal, also, tendons take a LOT longer than muscle to adapt to heavy lifting. 3. level 1. ramBOLO.
It provides you with everything you need to tackle both tennis and golfer's elbow, including massage techniques, stretches, and eventually strengthening exercises to utilize once you have improved enough to start with exercises. The guy that sells the program runs a forum where you can ask him any questions that arise.
