Make sure to tape your hands BEFORE you need to tape your hands. As for conditioning, if you can, get in the gym and work your arms, core, back and legs. Also work on cardio. If you can not get to a gym, Gordon Rathburn has a technique he recommends. Attach your handle to a post and lean into it like you are skiing. Using your arms and keeping your core tight, pull yourself in the direction of an upright position. Relax, aburptly dropping your body and catching yourself with your arms, again keeping your core tight. Repeat, ideally three sets of twenty, "skiing" in both directions. As opposed to real skiing, it is okay to let your elbows get away from your "vest" in this exercise. Make sure to get plenty of rest, drink a lot of water and wear sunscreen, especially on the tops of your feet. And pace yourself. Good luck and have fun!
