sharapova cant handle power and serena has lots of it
You don't say? Yeah Serena must eat a lot of Spinach. Probably has a high protein diet and supplements with Glutamine a Creatine.
Sharapova probably isn't using the right form when she lifts, probably not in the correct rep range. Probably not spacing her meals properly. Now that I think of it maybe she is overtrained and is experiencing some muscle atrophy. That's a shame.
