During some down time on the set of James Wan's Fast & Furious 7, Vin Diesel took advantage of his free time to get in some training for James Gunn's Guardians of the Galaxy.  Diesel may be pretty imposing on screen, but he needs a bit of help in the height department in order to play the tree-like Groot.  He posted a fun behind-the-scenes video featuring his training, along with a few words on both films.  As a special bonus, Diesel's co-star Djimon Hounsou, who will appear in both films, also makes a special appearance in the short video.  Hit the jump to check it out.  Fast & Furious 7 is due out July 11, 2014, and Guardians of the Galaxy will follow less than a month later on August 1, 2014.
