Your video clip on how to handle a shoulder injury was spot on and I'm hoping you have some advice on tendentious elbow. I'm pushing my way through some discomfort but definitely I'm avoiding pull ups some curls are an issue but I've been able to handle it.
"Pushing through" any injury is counter productive.
I have been injured MANY times, and if I did not take the time off to heal (you can always work legs when the tendonitis is flaring up), and rethought my technique, I would not still be in top shape.
The basis of my video is NOT over extending on any exercise, as that's what causes most joint problems. The stress and focus in every exercise has to be on the target muscle itself, and never the joints, or surrounding muscles. They call it the "mind-muscle connection".
I realize from experience that it is hard to step back, rethink and relearn how to do exercises, but pain and injury such as tendonitis is our body's way of saying we are not focused on doing the exercise correctly.
There are a lot of exercises in the DVD but keep in mind that the MECHANICS of all exercise is the same: you have to focus completely on what the target muscle is doing, and not overextend.
Whenever I do any single arm exercise, I always pick up the weight/handle/with BOTH hands, even when I don't have any tenderness or injury, in order to AVOID injury. I want all my effort to go into the exercise, not picking up a dumbbell or barbell plate. All your energy should go into the muscle that is being targeted by any given exercise.
Give the injury a week's rest, ice it, and take ibuprofen 4X a day to keep the inflammation down.
