Cameron Diaz Gets Super Sculpted Buff Biceps By A-Rod--How About You?

Ever since Cameron Diaz started getting chummy with Yankees slugger A-Rod, we've all noticed her going sleeveless, more and more. And we've all noticed her new, super sculpted buff biceps.

Just last week on Jimmy Kimmel, the California beauty walked out on stage in a tight, white tank top and suspenders, showing off her ultra-toned triceps and biceps.

Who can blame her? Cameron has worked hard to achieve those sexy, 'bad-ass' arms, and obviously, Alex Rodriguez has been a big influence because the good-looking duo work out together at the gym.

And there's the key: You must stick to a strong weight-training routine to develops guns like hers.

But here's a thought: Has Cameron Diaz over-killed her arms?!

You either love this Madonna-Kelly Ripa-Cameron Diaz look, or you don't.

It's a bulky appearance, and might not look so great with a delicate red carpet gown. But we are sure, many others would disagree with us.

Look at the photos above. The top shows the actress following a gym work-out with A-Rod just a few weeks ago. And the bottom pic shows us her at the beach back in August of 2009.

We wrote about Cameron Diaz' already buff arms back then, and how she got them:

..."Believe it or not, this is a simple exercise routine. And you can get the 3-step plan right from the mouth of her trainer, Teddy Bass. He gave out her toning tips to People magazine.

Bass' three-step arm workout for Cameron Diaz:

Reverse flies (15-20 reps done by stepping into a lunge and raising arms parallel to shoulders), Tricep kickbacks (10 reps per arm done in a lunge, leaning forward with a flat back and extending weights behind close to the elbows)And 15-20 reps of Bicep curls.

Now to get the super sculpted buff biceps by A-Rod, well, that's a much heavier work-out. And we applaud Cameron for going the distance to attain her new toned look
