Watch as 5X Mr. Olympia Phil Heath trains biceps after finishing off his back routine. Phil posted on his official Instagram page how much he enjoys doing preacher curls.

“Had a great back session tonight at @armbrustprogym that I had to throw in some biceps since I haven’t given them love lately. I always enjoy this preacher curl machine as it isolates my muscle in that perfect spot.”

From the amateur to the pro bodybuilder it all comes down to the same thing. There is no magic. It is asked a million times if you can train biceps with back. Well you your not going to get a better answer than this.
