The key is to perform them in the same manner as the full range reps but only partially. Many lifters do partials using different angles and end up not transferimg the power over to the targeted lift. They change the way they are done so the partial no longer resembles the full lift. Keep this in mind. Do a few sets of partials to augment your training.
Full range is still the best bet.
Last July I had a grade two tear in my left pec. I had xrays done and the ortho said it would heal fine, but four months later it is still so swollen it looks like I have an implant on one side. I'm getting a little concerned about being able to bench in the future for competitions. Anything above 185 for reps feels like it's going to tear again. I would really appreciate your input.
