try pleasuring two women at the same time manually, while reading Tolstoy, and doing a headstand =D. Wait am I allowed to go past PG-13 on the forums? If not, yes shadowboxing, focus mitt work with someone who knows how to feed the mitts *check out Duane Ludwigs numbering system for mitt work, really amazing* ladder footwork drills with the medicine ball I'm going to try *thank you Thomas J*, and if you're interested in any sort of cross training, handball will help develop eye/hand/footwork coordination as well.
